How to reference a bar by time?

[Billy Valentine]

Is there a way to reference a bar by its time, not by bars ago?

For instance, how would I reference the Open of the one minute bar that closed at 9:31 am?

Problem:
I wish to plot the 9:30 Open a horizontal line on a 1 minute chart on YM, but I am running a premarket session and CurrentOpen[0] plots the first opening price that appears on my chart and not the opening price of the regular session and I it is important to keep the premarket session.

This is what I have now:

DrawHorizontalLine("CurrentOpen", CurrentDayOHL().CurrentOpen[0], Color.White, DashStyle.Dot, 2);

Any solutions?

Thanks Ray, I'm still new at this. This is what I came up with and works just the way I intended:

if (ToTime(Time[0]) > 093000 &&
ToTime(Time[0]) < 160000)
{
//set the time of 9:30 bar
int barsAgo = CurrentBar - Bars.GetBar(new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 9, 30, 0, 0));
DrawHorizontalLine("CurrentOpen", Open[barsAgo], Color.Magenta, DashStyle.Dot, 2);DrawText("TodaysOpen", "Today's Open", 2, Open[barsAgo]+1, Color.Magenta);}
