So at this time theres no way to see the function conditionally. 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. It is versatile and can plot different styles of lines, histograms, areas, columns (like volume columns), fills, circles or crosses. It is evaluated at each iteration of the loop.

In the script's pane, whether your script is a chart overlay or in a separate pane. We can choose between those values we use the conditional operator or iff() function. I'm not sure how to reference array values when plotting. We cannot toggle those arrows with an if statement. When that argument has a colour value, the bar gets coloured. How do you get out of a corner when plotting yourself into a corner. 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 Pine Script's runtime and its built-in functions make loops unnecessary in many situations.

To count the number of up bars in the last 10 bars, they will use: The efficient way to write this in Pine Script (for the programmer because it saves time, This, for instance, plots a diamond only when the bars close is above the 10-bar exponential moving average: Its not impossible to use plotshape() with an if statement. Here, we use a function to create a label that only appears on the charts last bar. is an example of a script causing this problem: In order to help Pine with detection, you should add the max_bars_back We thus need another mechanism to pull that variables value from inside the functions local scope, while still being able to use the functions result. place. For example: Same as no viable alternative, but it is known what should be at that So we cannot use this function conditionally. 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. // Method #2: Plot a character in the bottom region of the display. If the box is checked, the plot the line. in an overlay script: This script shows other uses of plot() in a pane: plot() which means it is known at compile time, e.g. But neither can we set this functions argument with the conditional operator (? it makes for more readable code when you assign a condition to a variable name that will remind you and your readers of what it represents. Youll get but they can be controlled by varying their plotted values, or their color. The if statement doesnt accept the bgcolor() function. subsequent bar.
