In experimenting with a custom price index indicator, I can get it to plot in real time, but only in real time. As soon as the window is closed or chart time frame is changed, the indicator resets to zero and starts over. I can only get it to show history by keeping the chart window with indicator continuously opened and unedited.
How do I need to modify the code so that I can use it offline and have it plot history as well as update in real time.
Here is the complete code as is. I'd like to modify it so that it calculates history upon adding it to the chart and so that it also updates in real time. I understand that with a lot of history it would take much longer to calculate and load, so the best solution would be to add a variable number of historical bars to calculate and plot from.
