BackTest Time Frame

[kenb2004]

I trying to BackTest 1 day and can only backtest 2 days. Why is that? I am putting From 2/11/2011 to 2/11/2011, 1 day, but NinjaTrader gives me From 2/10/2011 to 2/11/2011. How can I backtest only 1 day?
Thanks

Hello,

THanks for your note.

What time frame and instrument are you doing this on?

Also what data feed provider are you connected too?

Hello,

This is determained by your session template.

What session template are you using. You will need to use a session template that is like the Default 24/7 session template that doesnt end at the end of trading for example instead ends at Midnight. However for the Default 24/7 to work 100 percent as you epect you would need to chang the session template to your time zone so that no time offset occurs.

Let me know if I can be of further assistance.

Hello,

Can you please give me the EXACT start time and date and end time and date please.

I look forward to assisting you further.

Session Template is Default 24/7 so it should start at 00:00 on 2/11/2011 and ends at 17:15 2/11/2011, (Friday) but the backtest brings back data from 00:00 on 2/10/2011 and ends at 17:15 2/11/2011, 2 days not 1 day.

Hello,

Was able to duplicate when I use your exact day.

I used the 14th for today and when you use 2/14/2010 as the test date it works correctly which is what I originally saw.

When using your date this occurs. I'm checking into development to see why this is the case.

Thanks for your patience.

Thank you for your acknowledgement that there is a problem. Let me know if there is a work-around..
thanks

Hello,

I have checked into development and this occurs due to the Default 24/7 session template.

Here is the information I got back from development:

When we request a bar series, we do that:
- including the session, which spans into 'from'-date
- including the session, which spans out from 'to'-date

in that very special case below, the minute session starting at 02/10/11 12:00 AM spans to 02/11/11 12:00 AM, which is the first timestamp of the from-date. And for that is according to our definition included into the request.

Therefor this is expected with the Default 24/7 session template. If you would like this not to occur you would need to use an ETH(Extended trading hours) template for example.

Let me know if I can be of further assistance.

"Starting at 02/10/11 12:00 AM" shouldn't even exist when you are setting "From" 02/11/2011 to 02/11/2011. This is really flawed! You guys are over complicating it. It should be From 0001 02/11/2011 to 2400 02/11/2011.

Hello,

Heres the non complicated version.

To get this to work as you expect, Do not use the Default 24/7 session template. If you backtesting CL use the Nymex Metals/Energy ETH session template.
