lookup bar index?

[michaelmakuch]

Is there any way to lookup a bar index given a date and time?

For instance I need to draw a line between the current bar (0) and back to a known date/time bar, but how does one determine the bar index? Or I need to lookup price for a known date/time.

As my script is called what do I need to do to record any interesting or critical data points? I.e. I can't record the bar index since it changes with every new bar.

Thanks,
Mike

Record the bar count when the historical point occurs by using histBarCount = getCurrentBarCount(). Then, to refer to the historical point in terms of barIndex, subtract the present barcount from the historical barcount to get the relative barIndex, e.g. relBarIndex = histBarCount - getCurrentBarCount()
