I noticed some interesting behavior in the indicator. It updates the highs and lows ( DrawText labels) as you scroll the chart and re positions them as you scroll. So the calculation and display are dynamic and keep the calculations in Sync with the last bar on the chart. In other words if you scroll backwards they reverse/undo themselves. I can see that the underlying calculations are all stored in custom data series, but the Labeled highs and lows that migrate are stored in a list which has only 1 value for each High or low and it only adds an element when its done migrating so I don't understand how they can undo themselves in an orderly fashion. Is there any examples of producing this type of display that you can point me to that might offer some explanation.
Thanks
Jerry
