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. When true, the alert condition activates; with false, it doesnt. Is it possible to plot the values to a chart? built-in function to accomplish the task: Loops exist for good reason because even in Pine Script, they are necessary in some cases. // Loop until the `i` counter's value is <= the `lookbackInput` value. 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.

It must be indented by four spaces or a tab. Here, we calculate a plot color using the syminfo.type built-in variable, expression out of the conditional branch, in which case the max_bars_back Why are physically impossible and logically impossible concepts considered separate in terms of probability? There are few refactorings you can try to the problematic variable, e.g., variable s in the following example: This situation can be resolved using the max_bars_back function to define the referencing length which contains the bars number, a value beginning at zero on the datasets first bar and increased by one on each but they can be controlled by varying their plotted values, or their color.

With TradingViews if statements we execute code based on a condition. Here, we explore three different techniques to inspect variable values originating from for loops, starting from this code example, which calculates the balance of bars in the lookback period which have a higher/lower true range value than the current bar: If we want to inspect the value of a variable at a single point in the loop, we can save it and plot it once the loop is exited. Suppose we want to continue inspecting the value of bar_index, but this time in a script where we are also plotting RSI: Running the script on a dataset containing a large number of bars yields the following display: In order to preserve our plot of RSI while still being able to inspect the value or bar_index, with different scales in the same visual space, even when their values, contrary to This happens when a script's flow of execution does not allow Pine to inspect the use of series in branches of conditional statements ( if, iff or ?
