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. ), and Pine cannot automatically detect how far back the series is referenced.

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. structure allows the repetitive execution of statements until a condition is false. A script can only plot in its own visual space, whether it is in a pane or on the chart as an overlay. plot() // Retrieve the value of the array's only element which was set from inside the function. We cannot access the _hlca variable used inside the function from the scripts global scope. You can't use plot statements in for loops or any other local block in a script. The root cause of the issue is that input.string returns a type of 'input string' which given that all the string options are 'const strings' seems like a rather odd choice. which contains the bars number, a value beginning at zero on the datasets first bar and increased by one on each A To subscribe to this RSS feed, copy and paste this URL into your RSS reader.

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. In this example it would be a straight line. When it is, that test turns up true and code inside the if statement runs. limitation of 1000 variables is applied to each function individually. But the conditional operator or iff() function neither help; this functions arguments cannot be set conditionally.
