How to know the index of the last bar on chart?

Hi, what I want is to know the index of the bar (which is its number since the most recent bar) so I can extract its date.

Any clue?

The latest bar is always 0 and the indices increase moving to the left of the chart. Time[0] will contain the date of the latest bar on any chart. Time[1] will have the date of the previous bar and so on.

Yes the problem is that my chart is from the most recent date (since today) and I'm seeing bars of 2001. Time[0] will just give me the time of the most recent bar.

I want the date of the last bar shown in the part of the chart I'm seeing, not the last bar on the whole chart.

You have to know something about the bar to determine its index such the latest, the bar 2 weeks ago or the last bar (on the left). If you know the time of the bar, use iBarFind() to determine its index. But of course you want the opposite which isn't possible.

I found how to do it.
This is it.
