may contain any number of single quotation marks, and vice versa: You can escape the strings delimiter in the string by using a backslash. Now you can easily see on each bar which test passed or failed. However, in order to cover the debugging topic completely, at least a couple of sentences should be written. String literals may be enclosed in single or double quotation marks, e.g. They are: Penrose diagram of hypothetical astrophysical white hole, MOSFET is getting very hot at high frequency PWM. and they never change during the execution of the script. Basically, data is stored in arrays. There are two ways to use tostring () (TradingView, n.d.): tostring(value) tostring(value, format) color.green, However, remember that this is just an example, you can change the shapes, colors, styles etc to make each test more memorable. Making statements based on opinion; back them up with references or personal experience. We must first convert the string to a value which can be plotted. 3 : 0, plot_color = opts == 'Hammer' ? Thanks a ton, that really helps me a lot. I often find that when I use this method, I avoid debugging completely. No void keyword exists in Pine Script, as variables cannot be declared using the void type. We will often use type to refer to the form type pair. 1 : opts == 'Hanging' ? Central limit theorem replacing radical n with n. Are there breakers which can be triggered by an external signal and have to be reset by hand? I want to try this as a workaround to offset value to the left. color.orange, int(), At any rate, I hope the article is useful. : Single and double quotation marks are functionally equivalent. y = close na values can be automatically cast to almost any type. Is the EU Border Guard Agency able to tell Russian passports issued in Ukraine or Georgia from the legitimate ones? Can you help me? While prices appear at the pivot, the pivots actually require, The hexadecimal letters can be upper or lower case. Note that when specifying red, green or blue components in color. We can use str.tostring to convert float to string, but is there a way to go from string to float or int? For example: Do not use the == operator to test for na values, as this method is unreliable. The const form is a requirement for the arguments to the title and shorttitle parameters in We can use this function in indicator (study) and strategy scripts. Note that plotting floats and integers is not completely plain sailing. Suppose you want to display the value of pivots on your chart. plot() or When using color built-ins, is possible to add transparency information to them with nz() function to replace it with the current bars Tuple elements can be of any type. objects can be created. For this, we will use the int() Now lets get back to the main topic. [] history-referencing operator) to one of the Pine Script types allowed for array elements: An array containing elements of type int initalized with one element of value 10 can be declared in the following, equivalent ways: There is a void type in Pine Script. and label.new(), How could my characters be tricked into thinking they are on Mars? All of these types exist in several forms. 1 : 0). Pine Script types identify the nature of a value. To add a manual setting to a script, its code has to include a special function. Especially if they are all plotted as simple blue line charts (the default plot values). This is because built-in variables such as open, There is also a special syntax for calling functions that return tuples, which uses a tuple declaration on the left side of the equal sign in what is a multi-variable declaration. Tradingview provides a tostring()function that makes it look like you could convert the most recent series value to a string and plot it only when certain conditions are met. Why is apparent power not measured in watts? color.red, the value of an expression or variable is undefined. Counterexamples to differentiation under integral sign, revisited. These inputs are stored in variables called user input variables. Backtest Rookies is a registered with Brave publisher! Is it correct to say "The glue on the back of the sticker is dying down so I can not stick the sticker to the wall"? Debian/Ubuntu - Is there a man page listing all the version codenames/numbers? Using different plotting styles and options can help some of your results stand out from the crowd. These type names are constructed by appending the [] suffix (not to be confused with the is it also possible to use scale.none on only one element of a larger script? There is no auto-casting rule that can automatically cast a float to an int, Thanks for contributing an answer to Stack Overflow! Built-in variables such as open, hl2, hlc3, ohlc4, etc., are not of const form. Would salt mines, lakes or flats be reasonably found in high, snowy elevations? // On all bars, calculate the maximum between the `high` and the previous value of `ath`. Now when we plot x_intusingplot(x_int)we are then easily able to see every time x is true in the time series. : Note that there is no plot or hline keyword to explicitly declare the type of . longTrigger := 1 - longTrigger/100 shortTrigger := 1 + shortTrigger/100. In Pine Script there is a special value called na, which is an acronym for not available, meaning Is it appropriate to ignore emails from a student asking obvious questions? study(Print Text, overlay=true) Thanks for contributing an answer to Stack Overflow! red : opts == 'Engulfing' ? The minimum and maximum values for a numerical input are set with the minval and maxval arguments. Strings should largely be debugged in the same way as boolean values. Examples of float values are 3.14 and -12.2572. Hey; thanks for the info, this was really helpful! I too was trying to find a work around to plot the ATR values but could not overcome the same limitations you stated above. What do I mean by "scaling issues"? Arrays in Pine Script are identified by an array ID. color.blue Except in function signatures, Pine Script forms are implicit in code; they are never declared because they are always determined by the compiler. For getting intergers out of floats, have you tried the round() function? for which we do not use an uppercase name because it is not of const form: Values of input form are known when the values initialized through input. Even better would be: There is an automatic type-casting mechanism in Pine Script which can cast (or convert) certain types to another. Floats and integers probably need no introduction. This line creates a new variablecalledx_int checks whether it is true. The input.source() function yields a value of series type not input. Variables of const form can be initialized using a literal value, or calculated from expressions using only literal values or other variables of const form. All Pine Script inputs. math.max() returns Pine Scripts label.new() function 2 : opts == 'Engulfing' ? I think that because of this, half the article covers the various plotting options. 0x9a2f88198224d59e5749bacfc23d79507da3d431. I would very much like to see your scripts, I learnt plenty of tricks and good coding practice from your examples. Why is Singapore currently considered to be a dictatorial regime and a multi-party democracy by different publications? Drawing IDs act like a pointer in that they are used to reference a specific instance of a drawing in all the related functions of its namespace. The IDs type is series line, series label, series box and series table, respectively, and an ID can exist in no other form than series. na value because more that one automatic type-casting rule can be applied. That would be incredibly useful! green : red, longCondition = sma_check and vol_check and close_check, shortCondition = not sma_check and not vol_check and not close_check, plotshape(2, title='SMA Check', color=sma_plot_col, style=shape.circle, location=location.absolute), plotshape(4, title='Vol Check', color=vol_plot_col, style=shape.circle, location=location.absolute), plotshape(6, title='Close Check',color=close_plot_col, style=shape.circle, location=location.absolute), study(title="Stochastic RSI", shorttitle="Stoch RSI", overlay=true, scale=scale.none), k = sma(stoch(rsi1, rsi1, rsi1, lengthStoch), smoothK), Click to share on Facebook (Opens in new window), Click to share on Twitter (Opens in new window), Click to share on Reddit (Opens in new window), Click to share on Pocket (Opens in new window), Click to email a link to a friend (Opens in new window), Rescale the boolean to something more appropriate. As I cant find a way to offset a value to the left, only to the right, I would like to see If I can achieve it by going from Float to String in July/2021 and from String to Float in May/2021. When would I give a checkpoint to my D&D party that they can return to if they die? Connect and share knowledge within a single location that is structured and easy to search. low, This is code that will not compile because we fail to convert the type of the argument used for length when calling dayofmonth all return values of type int. and may also contain the symbol e or E ta.ema() or For example, you could use the. A variable of series form can thus never be converted back to a simple form, for use with a function that requires arguments of that form. While the series form is the most common form used in Pine Script, it is not always allowed as arguments to Pine Script built-in functions. Tuples can be useful to request multiple values in one request.security() call, e.g. The full code follows: This article was originally intended to only cover debugging but grew in something slightly different as it was being crafted. I got the same error message as with your code. Here, the value of the sum and mult variables calculated by the function will be assigned to the s and m variables. Once you become familiar with the basics of converting everything to a float or integer, debugging becomes largely a question of taste, preferences and plotting. It is the multiline comment! The following image shows how it looks on a chart. The plotting functions only allow constant strings (strings that never change / or are not dynamically created). The Pine Script compiler can automatically convert some types into others when a value is not of the required type. It is similar to the null value in Java, or None in Python. var _low = float(na) This will be interpreted as "series float" var float[] _low = na This will be interpreted as undetermined type . any ideas of how to get rid of the 0.0000? please paste the code with the round () function and i will try it in tradingview to see what the results look like , an approximation of the results i posted in the images attached. The code below will change the background colour of the main chart when the RSI indicator is overbought or oversold. How to make voltage plus/minus signs bolder? timenow, Drawings were introduced in Pine Script v4. box(), and rev2022.12.9.43105. We need to convert this to 1.05 for our if statements. To help visualize what I am talking/ranting about, take a look at the following chart: Wouldnt it be nice and clean to plot 0.0059below the words ATR? Understanding all three is key to making the most of the power of Pine Script. label.new(x, y, txt). As alluded to throughout the article, the final thing we should be wary of when debugging is the scale that each line takes. They are: Each fundamental type refers to the nature of the value contained in a variable: 1 is of type int, 1.0 is of type float, "AAPL" is of type string, etc. It was also already there in Pine v4. As mentioned above, debugging strings is very similar to debugging Boolean values. Can a prospective pilot be negated their certification because of too big/small hands? document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Tradingview: Pinescript Debugging, Plotting, Tips and Tricks, plotchar(nb, location=location.abovebar, text="ATR"), //plotchar(nb, location=location.abovebar, text=tostring(atr)), opts = input(defval='Hammer', title='Operation Mode', options=["Hammer", "Hanging", "Engulfing"]), operation_mode = opts == 'Hammer' ? I want to try this as a workaround to offset value to the left. it can never be converted back to a weaker form. Is there any reason on passenger airliners not to have a physical lock between throttles? The notion of time series is intimately linked to Pine Script's execution model and type system concepts. Support this site by clicking the referral link before you sign up! Where does the idea of selling dragon parts come from? See the Type casting section of this page for more information on type casting. An expressions result is always of the strongest form used in the expressions calculation. For example, lets say you are plotting on an intra-day chart but would like to know what most recent daily ATR value is. The result is often a long exercise of commenting and uncommenting different plots. function to force the type conversion of the value we supply as a length to ta.sma() from float to int: Explicit type-casting can also be useful when declaring variables and initializing them to na which can be done in two ways: // same as #FF0000, fully opaque red color. : The internal precision of floats in Pine Script is 1e-10. These objects are created with the Debian/Ubuntu - Is there a man page listing all the version codenames/numbers? * and ticker. Instead I went to plot lines (hline) for the high and low of the ATR. Such a float value is a number with digits after the decimal point (. The form expresses when a value is known. Expressing the frequency response in a more 'compact' form. If you have lots of test plots that you do not want to display all of the time, then knowing this simple keyboard shortcut can significantly speed up the time spent commenting and uncommenting. Not the answer you're looking for? ). Donate with PayPal using any payment method you are comfortable with! var keyword so they are only initialized on the first bar of the dataset. time or Pine script at it's core just takes in time series data, passes that data through functions and outputs it as a strategy or indicator. Find centralized, trusted content and collaborate around the technologies you use most. label(), The type system is intimately linked to Pine Scripts execution model and time series concepts. Thanks. In addition, even if you do not know which line is which, you can easily see that the first line failed and take a look at the line title. The following code will perform a check on which option has been selected then change the plot value and colour accordingly: Now we have the basics down, lets move onto some topics and general plotting advice that can make your life a little easier. Performance & security by Cloudflare. The special types all contain IDs referring to an object of the types name, e.g., a variable of type label contains an ID (or pointer) referring to a label, and so on. Your IP: If you try to plot a boolean value directly in the plot()function you will receive the following error: Add to Chart operation failed, reason: line 130: root_data expression of plot_11 has invalid type: series__bool expected series, In order to debug a boolean value, we need to first convert it to a valid type. ta.sma(): The code fails to compile with the following error: If you have complex entry/exit criteria filled with different filters and confirmations, it can be difficult to identify why your script did or didnt do something. Pine Script forms identify when a variables value is known. Ready to optimize your JavaScript with Rust? This is something we will look at in a bit more detail later. The code above has three simple checks for the purposes of the example. syminfo.type See str.tonumber() na value from propagating in a calculations result on all bars. Version 4 of the compiler provides a way to print some text as a label: //@version=4 When these values are changed, this always triggers a re-execution of the script from the beginning of the charts history (bar zero), The [] operator is used to access series of data. While it is possible to write very simple scripts without knowing anything about the type system, Once you convert it and run the dtypes command again, you'll see that your target column is a floating point. Input.integer. debug=input(false,title=Show Debug Plots?) This is especially the case if your code following needs to make decisions based on the selected option. To modify the data frame, you can either overwrite the existing column or add a new one. line(), Without the ability to print to the terminal, we are forced to plot anything and everything we wish to inspect. What do I mean by scaling issues? Values of simple form are known only when a script begins execution on the first bar of a charts history, How many transistors at minimum do you need to build a general-purpose computer? To learn more, see our tips on writing great answers. time, Another method I use for making it easy to work with debugging plots is to use an input statement to enable turning them on and off in the settings window, instead of commenting the lines. Luckily there's one helper function that makes text from numbers. Uncomment plots (if any) designed for the main chart and then plot the text plots to a subplot (. Although any float or integer value can be plotted to the chart, you might run into scaling issues. but rather an overloaded version of a subset of Pine Script types which represents the type of an arrays elements. If you have ever tried to plot a string using the textvariable in one of the plots which supports it, (e.gplotshape(), plotchar()etc) you might have spent a lot of time debugging strings. Thanks for contributing an answer to Stack Overflow! Or, I have not found the magic source at least. Highlight a large chunk of code then pressCTRL+/(or Option+/for mac users). Received a 'behavior reminder' from manager. close, These functions determine the values that can be modified by script users in the scripts Settings/Inputs tab. The factor for that is 100 (10^2). The type Understanding all three is key to making the most of the power of Pine Script. QGIS expression not working in categorized symbology, What is this fallacy: Perfection is impossible, therefore imperfection should be overlooked. Where does the idea of selling dragon parts come from? Here there. Find centralized, trusted content and collaborate around the technologies you use most. Floating-point literals contain a delimiter (the symbol .) A real time saver when switching from test plots to your indicator plots. na if one of its arguments is na: To protect against this, we could instead use: where we are replacing any na values of ath with zero. The compiler is telling us that we supplied a float value where an int is required. Why is Singapore currently considered to be a dictatorial regime and a multi-party democracy by different publications? green : na, strategy("Traffic Lights", overlay=false), close_plot_col = close_check ? This can unlink the indicator from the price scale. The syntax to define a user-defined type is: In this example, we create a UDT containing two fields to hold pivot information, Authentic Stories about Trading, Coding and Life. The action you just performed triggered the security solution. An argument of const float type was used but a series int is expected;. Your solutions will greatly help in the mean time. Boolean variables that are variables that are eithertrue or false. Pinescript and trading concepts explained really well. float symbol_close = request.security (array.get (symbol_array, 0), timeframe='D', expression=close)" // to be equivalent to "request.security ("NASDAQ:AAPL", timeframe='D', expression=close)" the problem is that array.get () returns a "string series" and the request.security () expects a "simple string" as parameter close, For those interested, the chart above was created with the following code: If take the code above and uncomment the last plotline, you will receive the following error: Add to Chart operation failed, reason: argument "text" accepts only constant string values.

To access it, open a script with //@version=4 in it and select the "Convert to v5" option in the "More" menu identified by three dots at the top-right of the Editor's pane: Not all scripts can be automatically converted from v4 to v5. Penrose diagram of hypothetical astrophysical white hole. We can use str.tostring to convert float to string, but is there a way to go from string to float or int? In v4, you need to change the values used in plotting. We should adjust our plotting accordingly. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. This is because we may often think the code should have done something but after reviewing the check that failed, we quickly realize it is correct and move on. Making statements based on opinion; back them up with references or personal experience. This will require converting values into strings, Cannot call ta.sma` with argument length=len. Tuples are a syntactic arrangement of variables, e.g., [macdLine, signalLine, histLine]. is higher than the previous one. table.new() functions. It is a bit hard to say without seeing the code. They are: int, float, bool, color, string, line, label, plot, hline . Note that using the := operator to assign a new value to a previously declared const variable will transform it into a simple variable, e.g., here with name1, If any readers out there know a workaround or something I have missed, I would LOVE to know. Such values include close or hlc3 or any variable calculated using values of series form. A string enclosed within double quotation marks In such scenarios there a few options we can take: The image above shows an example of plotting an RSI over the main chart using scale.none. The letter pairs represent 00 to FF hexadecimal values (0 to 255 in decimal) where: Pine Script also has built-in color constants such as Integer literals must be written in decimal notation, e.g. const variables cannot change during the execution of a script. But obviously the number is float again. In general, you will not run into many scenarios where debugging strings is needed. The result of a function such as calcSumAndMult() that returns a tuple must be assigned to a tuple declaration, i.e., The series form contains a series variable. Do not make the mistake of assuming this is strictly beginner's material; some of the questions and answers explore advanced techniques. Each plotted line is referred to in the fill() : Built-in variables such as (which means multiply by 10 to the power of X, where X is the number after the symbol e), e.g. A simple form argument is also required for the length argument of functions such as as would be the result of expressions calculated using them. However, it can be useful if you use the options parameter in theinput()function. This does the job kind of nicely. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data. and so 0 is stored to x_int. Here, we add a field to our previous pivotPoint type that will hold the pivot information for another pivot point: Two built-in methods can be used with a UDT: new() and copy(). The void type means no value is returned. But avoid .

Both lines must have been plotted with either plot() or Converting Pine Script into MQL4 language (Easy Indicator), Pine script how to feed array data from Tradview into pine script value, Need help converting a pine v2 script to pine v4, Pine script is converting the result of a simple calculation from an int to a series[float]. Pine Scripts fill() function fills the space between two lines with a color. color.new. returns a string corresponding to the sector the charts symbol belongs to, eg., "crypto", "forex", etc.). There are 5 forms of types: literal, const, input, simple and a series. Any ideas how to run this code in Pine Script v4? color(), Modified today. table(). Types, however, can be specified when declaring variables, e.g. This is a compendium of frequently asked questions on Pine. There is a built-in function for that in Pine v5. Color literals have the following format: #RRGGBB or #RRGGBBAA. If it is, 1 is stored to x_int. bool(), Because they change bar to bar, they are of series form. The type argument allows for specifying the kind of input: with integer we get an input for whole numbers while float makes a floating-point input that allows for using decimal values. Functions can either be user specified or fortunately pine script comes with the vast majority of functions you'll likely need built in. Read about them in the Objects page. We then divide back by 100 to get the original scale back: 1.34. Currently i am working with pivotpoint[1] and pivotpoint[0], but the program does not discard the third most recent pivotpoint once a new pivotpoint is formed. How did muzzle-loaded rifled artillery solve the problems of the hand-held rifle? When specifying transparency in such functions, it is in the form of a 0-100 value (which can be of float type to access the underlying 255 potential valoues) To use the above custom function we simply do: truncate (1.83495, 3) // Returns: 1.834. It contains series of data associated with the candlestick chart like open, high, low, close. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. For example: Here, the compiler cannot determine if myVar will be used to plot something, as in plot(myVar) where its type would be float, or to set some text as in It may sometimes be necessary to cast one type into another because auto-casting rules will not suffice. When your script doesnt enter, it becomes immediately obvious which entry check or filter is holding it back. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, i tried to use the round function but it did not changed the final result , maybe i was wrong on syntax , i am new to this language . Functions such as barssince() or One method of doing this is to use aternary conditional operatorto convert it to a float for plotting. keyword allows the creation of user-defined types (UDTs) from which Variables of const, input or simple forms cannot change values once execution of the script has begun. The form hierarchy translates into the rule that, whenever a given form is required, a weaker form is also allowed. With the input.float () function we create a float (that is, fractional numerical value) input in the script's settings window [1] . x = bar_index Not sure if it was just me or something she sent to the whole team. The Pine Script Editor includes a utility to automatically convert v4 scripts to v5. crossover() yield a result of series form because it varies bar to bar, // Declare `ath` and initialize it with `na` on the first bar. and also I mad a coy of plotchar in many lines with all the possible conditionals and it worked but I got tones of 0.00000 0.00000 on top where the description is.

This will comment out the whole block of highlighted text. : Values of const form must be known at compile time, before your script has access to any information related to the symbol/timeframe information it is running on. function using IDs which are of plot or hline type, e.g. Take the following example where we assume xis a variable that is storing a trueorfalsevalue. Over the next few paragraphs, we will cover the basics of plotting each type of variable and then move onto some tips and general advice. Help us identify new roles for community members, Proposing a Community-Specific Closure Reason for non-English content, Pine Script: extract current value from indicator. They are: The fundamental types: "int", "float", "bool", "color" and "string" The special types: "plot", "hline", "line", "label", "box", "table", "array" "void" tuples Do you have any tips on how to select prices only for X bars back in time? A tuple is a comma-separated set of expressions enclosed in brackets that can be used when a function or a local block must return more than one variable as a result. box.new() and For example: You can concatenate strings using the + operator. Pine Scripts Style guide recommends using upper case SNAKE_CASE to name variables of const form. See the page on colors for more information on using colors in Pine Script. To convert an integer (or string) column to a floating point, you need to use the astype () series method and pass float as the argument. Asking for help, clarification, or responding to other answers. In Pine Script, the built-in variables open, high, low, close, volume, time, If not, then the value must be false (because it certainly is not true!) Pine has 9 fundamental data types. Pine Script has several types of inputs. line 27: Undeclared identifier dashed; var_1 : na, color=red, linewidth=3, title=var_1 (plus any descriptive text)) Note that of all these forms, only the series form allows values to change dynamically, bar to bar, during the scripts execution over each bar of the charts history. UDTs are composite types; they contain an arbitrary number of fields that can be of any type. Tuples can also be used as return results of local blocks, in an if statement for example, They cannot be used in ternaries, however, because the return values of a ternary statement are not considered as local blocks. To plot a float or integer, just stick it inside a plot()call as the first parameter and you are good to go. They are the bread and butter of plotting. the time of the pivots bar so variables of input form are always known when the script begins execution, and they do not change during the scripts execution. You have a gift. The tostring () function converts a numerical value into a string of text (TradingView, n.d.). Asking for help, clarification, or responding to other answers. I am trying to build a dynamic trend line indicator using ONLY the two most recent pivot points. Please help me , i need the somehow to get a result like in the picture attached. Pine Script types identify the nature of a value. Admittedly, the little detour above might not tell you how to debug a string but I hope it might just save you some head-scratching time. To learn more, see our tips on writing great answers. When debugging lots of different values, it can be difficult to easily recognise which line represents which variable. Since we are not able to print to the terminal, our only option for inspecting variables is to plot everything we need to check. and it is used to test a conditional statement or operator, the false branch is executed. There is no single type representing an array ID, Cheers ! // Explicitly declare the type of the new variable. it does something (triggers an alert event), but it returns no useful value. In this example, we define a condition that is true when the bars close and when a bool value is required, an int or float value can be used in its place. so we will need to do the job ourselves. Is it possible to convert String into Float or int in PineScript? However, before we move onto some debugging examples, allow me to take you down a side track on a loosely related topic. Note that plotting floats and integers is not completely plain sailing. 1.23223 // Literal float (currency price) 5 // Literal int "Hello world" // Literal string true // Literal bool Series form. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. As per our style guides recommendations, we use the Input suffix with our input variables to help readers of our code remember the origin of these variables. Input.bool. All these are valid variables that can be used as arguments for those parameters when calling the function: The reason for the error is that the NAME variables calculation depends on the value of * families, for example, Take a look at the docs by CTRL + Clicking on a plot type to see them all. In some cases, however, the Pine Script compiler cannot automatically infer a type for an If you directly plot the complete ATR values on the main chart, it could end up being cluttered and run into scaling issues. In my opinion, it would be cleaner to just plot the values above the bar at regular intervals. red : rsi < 30 ? all return results of simple form because their value depends on the charts symbol, which can only be detected when the script executes on it. If he had met some scary fish, he would immediately return to the surface.

Do non-Segwit nodes reject Segwit transactions with invalid signature? References Pine Script Language Tutorial (n.d.). Pine Script v5 User Manual v5 documentation, const for values known at compile time (when adding an indicator to a chart or saving it in the Pine Script Editor), input for values known at input time (when values are changed in a scripts Settings/Inputs tab), simple for values known at bar zero (when the script begins execution on the charts first historical bar), series for values known on each bar (any time during the execution of a script on any bar), The fundamental types: int, float, bool, color and string, The special types: plot, hline, line, label, box, table, array. Designing your calculations so they are na-resistant is often useful. Site design / logo 2022 Stack Exchange Inc; user contributions licensed under CC BY-SA. From $0 to $1,000,000.
