The if statement doesnt play well with plot(). For that we can use the conditional operator (? // Line stays on the chart but will no longer be extend on further bars. Therefore, if it is impossible to determine the correct size of the buffer, this error may occur. If we wanted to show only one level, we could use the same technique while isolating a specific loop iteration as we did in the preceding example. Want to know more about me? any ideas of how to plot it? In order to prevent the. or, can be a literal, a variable, an expression or a function call. You are telling Pine Script to plot the highs and lows with the given color setting, and the given linewidth setting. You can increase this amount up to a maximum of 500 by using the max_labels_count parameter in your scripts study() or strategy() declaration statement. Wasn't expecting a logical solution, this being Pinescript and all. For example, if youll have 5000 bars, and indicator takes 200 milliseconds to In the above example, study () and the if statement are examples of that. I would like to plot this to the last 10 candles and have it move over every time a new candle is formed. loading. But if you will declare a function that calls But not any action (function) can run inside an if statement. It types our one-line f_print() function in a script and on a second line, Copying the variableName variable name or the close > open conditional expression to the clipboard and hitting CTRL-SHIFT-F will, respectively, yield: The third line triggers on CTRL-SHIFT-P. For example, this makes bars that closed higher orange: barcolor() can work alongside an if/else statement though. For example: As strings manipulated in Pine scripts often do not change bar to bar, the method most frequently used to visualize them is to draw a label on the datasets last bar. // Method #6: Change the background's color. built-in function to accomplish the task: Loops exist for good reason because even in Pine Script, they are necessary in some cases. What we can do is set the functions series argument with a condition. When that argument has a colour, the background is coloured. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. To decide between those two we can use the conditional operator (? If you are planning to merge two signals in one script, first consider the scale of each. We can use this feature to write a functionally equivalent script: Values inside for loops cannot be plotted using plot() calls in the loop. or plot values using na color Pine Script v5 User Manual v5 documentation, Looking back in history to analyze bars using a reference value that can only applies to variables created both explicitly and implicitly.

When false, 0, or na the shape doesnt show. close Retrieved on August 5, 2019, from https://www.tradingview.com/pine-script-reference/v4/. avoid this issue: The error appears in cases where Pine wrongly autodetects the required The technical post webpages of this site follow the CC BY-SA 4.0 protocol. i.e., the last value calculated on the loops last iteration, We cant run plotchar() inside an if statement. When that argument has a colour value, the bar gets coloured. This page demonstrates the most useful techniques to debug Pine Script code. Attempting to assign mysize via switch: var mysize = switch ShapeSize "Size.small" => size.small "Size.normal" => size.normal => size.tiny or ternary statements: When it is, that test turns up true and code inside the if statement runs. subsequent bar. structure allows the repetitive execution of statements until a condition is false. This plotColour variable gets one of two values. Because compound conditions will only perform as expected if their individual conditions trigger correctly, you will save yourself many headaches if you validate the behavior of individual conditions before using a compound condition in your code. // Need to check that array size still warrants a loop because we may have deleted array elements in the loop. They cant be placed in user-defined functions or structures like if, The fourth call plot a gray circle at the bars, The last plot requires some preparation. With this function this strategy stops based on maximum drawdown (TradingView, n.d.). David from BigBits is an experienced . but you can also use plot() like this: Pine Script has an hline() function is the most frequently used function used to display information calculated using Pine scripts. Our example script plotted the value of the bar_index built-in variable, which will prevent the execution of the while loop If the box is checked, the plot the line.

Reddit and its partners use cookies and similar technologies to provide you with a better experience. declare a variable as a security function call and then use that variable as when no plot is needed. That plot should only show on Monday, so we place the plot() function inside an if statement: But this script doesnt work. The plot() function displays a series of data on the chart (TradingView, n.d.). My code is GPL licensed, can I issue a license to have my code be distributed in a specific MIT licensed project? There are 2 ways to go about this, depending on your requirements: either with multiple plotshape() calls or with labels. Is it possible to plot the values to a chart? source code.

This line, for example, plots a start whenever the condition (two bars in a row that close higher) is true: With an extra step we can also use plotchar() with an if/else statement. The scale in the preceding screenshot has been manually expanded by clicking and dragging the scale area so the content of the indicators display area content could be moved vertically to show only its relevant part. This code uses the % (modulo) operator to include values from every second loop iteration: The two techniques we use most frequently to debug our Pine code are: to plot variables of type float, int or bool in the indicators values and the Data Window, and the one-line version of our f_print() function to debug strings: As we use AutoHotkey for Windows to speed repetitive tasks, we include these lines in our AutoHotkey script (this is not Pine code): The second line will type a debugging plotchar() call including an expression or variable name previously copied to the clipboard when we use CTRL-SHIFT-F. In this script we have written the f_hlca() function to calculate a weighed average: We need to inspect the value of _hlca in the functions local scope as the function calculates, bar to bar. What gives? So you can try to switch to version 2 by for that variable only. Here, we save the value of tr in the val variable at the loops last iteration: When we want to extract values from more than one loop iteration we can use lines and labels. See, Our pivots are detected three bars after they occur because we use the argument, The last plot is plotting a continuous value, but it is setting the plots color to, The blue dot indicates when a new high pivot is detected and no plot is drawn between the preceding bar and that one.

This gives us a general idea of the values being used in each loop iteration: We can also extract multiple values from loop iterations by building a single string which we will display using a label after the loop executes: When loops with numerous iterations make displaying all their values impractical, you can sample a subset of the iterations. The state of multiple individual conditions can be displayed using a technique like this one, where four individual conditions are used to build our bull compound condition: Variables in function are local to the function, so not available for plotting from the scripts global scope. Whats happening here is that the thin blue line of the plain, We then plot navy blue crosses and circles on the body tops and bottoms. Not the answer you're looking for? alertcondition() calls, e.g. Pine-Script - can't use IF on PLOTSHAPE, solutions? // Loop until the `i` counter's value is <= the `lookbackInput` value.
