But if you will declare a function that calls after compilation: Usually this error occurs in version 1 pine scripts, and means that code : plot() calls When we already have other plots going on and adding debugging plots of variables whose values fall outside the scripts plotting boundaries would make the plots unreadable, another technique must be used to inspect values if we want to preserve the scale of the other plots. is incorrect. Some types of calls count for more than one in the total plot count. For example, this makes bars that closed higher orange: barcolor() can work alongside an if/else statement though. But what does that mean? What the code does is based upon user input. If the box is not checked do not plot the line. We could, for example, plot both RSI (0 to 100) Here, we use a function to create a label that only appears on the charts last bar. expression out of the conditional branch, in which case the max_bars_back 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 Script 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 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 Script 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. This website aims to help people like you reduce their programming curve.

That way our script takes specific actions in certain situations. If I try to run it, I get: cannot use 'plot' in a local scope. while structure: We use input.int() But that requires we make a separate variable first: The bgcolor() function colours the charts background from top to bottom (TradingView, n.d.). To learn more, see our tips on writing great answers.
