Hello buylosellhi,

You can work with GetBar() to return the # of bars ago that the specified date / time occurred.

http://www.ninjatrader.com/support/helpGuides/nt7/getbar.htm

If you want to caputure the CurrentBar index at a specified date / time, you could use something like this:

#region Variables
private DateTime myDateTime;
private int myCurrentBar;
#endregion

OnBarUpdate()
if (Time[0] == myDateTime)
myCurrentBar = CurrentBar;

Ryan, thanks for your reply. does GetBar() look for an exact match to timestamp or does it return the nearest bar if an exact match is not found

[NinjaTrader_RyanM1]

It doesn't require an exact match. It will look for the closest.

great, thats exactly what i was looking for.
thanks for your reply.

GetBar help

I've read this thread and want to make sure I am understanding---

Lets assume I am wanting to mark on a 10 second chart where a hypothetical trade was entered (I am reading these hypothetical trades from a file)--and the trade is timestamped:

entry time: 5/19/2011 8:00:19 AM

assume my bars on a 10 second chart have the following times:

Bar 100: 8:00:10 AM

and

Bar 101: 8:00:20 AM

and

Bar 102: 8:00:30 AM

which (if any) bar # would it return?

Hi Jim,

In this example, I would expect that GetBar() identifies bar 101 as the bar index. It's the first one (from left to right) that's newer than the time you're checking for.

Returns the bar index of the 1st bar from oldest to newest that matches the time stamp based on the DateTime parameter passed in. If the time stamp passed in is older than the 1st bar, a bar index of 0 is returned. If the time stamp is newer than the last bar, the last bar index is returned.
