Optimizer always same results

[bbucha_stk]

I run the optimizer for lets say Nov 2010 to Dec 2010 and I get 55 total results
I then change the start date to Jan 2010 same end date still get 55 total results.

I then hit the back test got something like 167 results (Same Han to Dec)
Then ran Optimizer and now it had this 167 result count???

bbucha_stk, with which NT release version are you working here (you can check under Help > About) ?

Which strategy and market were you testing on as those results were displayed?

[bbucha_stk]

I am using NT7 and running the 6E.
I am getting different results with backtest vs Optimizer on same data setting.

[NinjaTrader_Bertrand]

Ok, which strategy are you using? Please the default SampleMACrossOver strategy we ship with NT7.

When I for example run this setup and backtest on a minute chart using default sessions and paramters of 10 and 25 I get identical results for backtest vs optimize. If you optimize you may use different settings as 'best' settings, so this would explain a deviation from the results the backtest would show then.

I will try the SampleMACrossOver strategy as requested
By the way I was very careful to make sure I was using the same strategy and parameter settings in my strategy. Stay tuned.....

I did a reload historical data and it seems to work ok now. Thanks
