Then we make a custom script setting with the input () function. :) or the iff() function. And neither can functions that affect every script calculation, like the risk management rules and the alertcondition() function. plotted values will not affect the scale of the scripts visual space. and how no plot is drawn. 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. Pine Scripts runtime and its built-in functions make loops unnecessary in many situations. in an overlay script: This script shows other uses of plot() in a pane: plot() To avoid this, you need to use max_bars_back(time, n). The result should look like this: All from six lines of code!
