We also use a label to display, for each line, the loops index and the lines value. 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. Wicked local police scanner plymouth ma - pbuk.vida-brautatelier.de Displayed below are two scripts of the same indicator output..the first is the attempt to modify the script to MTF using the security () function, and the second is the script without MTF that works perfectly using global scope resolution="" defined in the study header.
