getBarIndexAt

Just been looking at the getFirstBarIndexOfDay() function and some other "index" functions such as getCurrentBarIndex() etc.

I'm trying to get the bar's index value from a Date() object that I've created. Say I've created a date object with the value of "7/7/2010 02:00:00 PM" and now is "7/8/2010 10:00:00 AM". I want to find the bar index that corresponds with my date object "7/7/2010 02:00:00 PM".

How would I do that?

Just thinking out aloud I should be able to find that myself by iterating backwards through the bars and doing a comparison on that bar's Date object with the one I've created right?

If that would work, then how would I get the Date object for bar index (say) -20?

That is correct. You can use a while statement to loop back through the bars

Retrieve the rawtime from your Date object using the .getTime() method and then evaluate that against each bar's rawtime() as you loop back. Note that the .getTime() method returns milliseconds whereas rawtime() returns seconds so you will need to adjust for that
