SystemPerformance when Strategy not attached to a Chart

[pmaglio]

Hi,

Following a customer issue I noticed that SystemPerformance is always empty if the Strategy is attached to Control Center instead of a Chart.

Using the example #1 from the help ;

http://ninjatrader.com/support/helpGuides/nt8/en-us/tradecollection.htm

and adding a line to Enter Long on each up bar ( see example attached )

If the Strategy is Enabled on a Chart it prints correctly the results of each trade.
If it is attached on Control Center without using a Chart, then there are no results

If there is another way to calculate the trade results, just let me know

Thanks
Pablo

Hello pmaglio,

Thank you for your post.

Please use SystemPerformance.AllTrades.TradesCount and advise if the TradesCount is 0 as well.

You can find information on TradesCount at the following link: http://ninjatrader.com/support/helpG...radescount.htm

Please let me know if you have any questions.

Thanks for your help,
I see that SystemPerformance.AllTrades.TradesCount has the correct number of trades
while SystemPerformance.AllTrades.Count is zero ( only when not attached to a chart )

The problem now is that
Trade lastTrade = SystemPerformance.AllTrades[SystemPerformance.AllTrades.TradesCount - 1]; tries to access a null array

May be Im doing something wrong ?
Im stuck here :

Hello pmaglio,

Thank you for your patience.

I was incorrect, you do not replace Count with TradesCount. You would still use Count but would include the following in the Configure State of your strategy:

IncludeTradeHistoryInBacktest = true;

For information on IncludeTradeHistoryInBacktest please visit the following link: http://ninjatrader.com/support/helpG...inbacktest.htm

Please let me know if you have any questions.
