Summation of previous bars

[jmflukeiii]

Can someone point me in the right direction to learn how to create a loop (or whatever is necessary) to do the following:

While a certain condition is met, add the result of an indicator (such as volume) on each successive bar and store it as a double or int that can be plotted.

Thank you for any tips.

Though you could use a loop, that looks like a straight accumulation scheme is what you need: loops are generally inefficient, and I avoid them if I can find another method.

 
private double TotalSum = 0;

 
bool ConditionMet = false;
 
// code to evaluate and set ConditionMet goes here
 
if (ConditionMet)  TotalSum += Volume[0];
else TotalSum = 0;

For Volume, you probably do want to use int: double is just a more general illustration of the principle.

koganam, as always, thank you for your help

If I have an indicator that plots both in a separate indicator panel (using plots) and then places lines on the chart, how do I set this up in the script?

Thank you

EDIT: With a quick search, it looks like that is not possible. I'll create two indicators

Look up DrawOnPricePanel.
