SA not changing date

[ATI user]

I ran 3 nov in SA Optimizer...no problem

I then changed date to 11 nov and it ran 3 nov again....does not matter which date I put in, it still runs 3 nov

only way to get it to change is to change instruments from YM 12-08 YM to YM 09-08 to run 8 aug...no problem

then try to change back to YM 12-08 to run 11 nov and I still get 3 nov.....

I can run 29oct and it plots the chart and list the data...however the date in the title bar still says 3 nov

I can not run any of the other days in nov without getting the chart and data for 3 nov

Hello,

Is this the from or the to date?

I can't reproduce this. I am able to change the from and to dates in the optimizer and they save the last date I ran each time. This is the expected behavior.

[ATI user]

from and to dates are both set to the same date...i.e. only running one day

i traced the problem to having MarketReplay open in another workspace...it was set to 3 nov and so every time i tried to run a nov date, SA was giving me 3 nov

so...with MR off...I can run all dates (one at a time) except 11 nov... <-- problem 1

problem 2 --> i can only get SA to run the first day if I try for a whole week...for instance running 3 nov thru 7 nov it only executes for 3 nov...this could be my strategy...will try with sampleatmstrategy and report

sampleatmstrategy does not optimize without adding some parameters

question: does SA not work with AtmStrategyCreate etc.?

I had to add code :

SetTrailStop(CalculationMode.Ticks, StrategyAnalyzerTrail );
entryOrder = EnterShort();

etc..in order to get SA to make trades

Hello,


For post #4 please provide the exact steps you are taking so I can reproduce this behavior. Please do it with SampleMACrossOver.

For post #5, this is because this strategy has if(Historical) return; in OnBarUpdate(). This strategy is not meant for backtesting or optimizing.

Hello,


For post #4 please provide the exact steps you are taking so I can reproduce this behavior. Please do it with SampleMACrossOver.

1. start NT...open a workspace with 2 charts....start MarketReplay for 3 nov

2. close workspace but not MR

3. open workspace for strategy analyzer (nothing running but SA...ie. no charts)

4. optimize YM 12-08 contract for 3 nov to 3 nov...change one parameter in SampleMACrossover

5. optimize for 11 nov to 11 nov....SA still gives you 3 nov chart and results

6. optimize for 29oct to 29oct ....SA still gives you 29oct AND 3 nov chart and combined results

7. optimize for 11 nov to 11 nov....SA still gives you 3 nov chart and results only

8. disconnect MR

9. optimize for 11 nov to 11 nov....SA still gives you 3 nov chart and results only

10. optimize for 10 nov to 10nov....SA still gives you 10 nov chart and results

11. optimize for 11 nov to 11 nov....SA now works properly

12. optimize for 3 nov to 7 nov....SA works properly

bottom line....MR overrides SA if MR is on (when I switched workspaces I did not realize I had left MR on)

Hello,



For post #5, this is because this strategy has if(Historical) return; in OnBarUpdate(). This strategy is not meant for backtesting or optimizing.

by 'this strategy' I assume you mean SampleAtmStrategy....historical is not the problem

to test my theory that AtmStrategyCreate code does not work in SA

1. save SampleAtmStrategy as SampleAtmStrategymod....comment out

// if (Historical)
// return;

add code to plot a dot...

if ( Close[0] < Open[0] )
DrawDot("cross"+CurrentBar, true, 0, Open[0]+2,Color.Red);

optimize and chart plots dots....however does not make trades

2. create a parameter called offset...

private int offset = 0;

[Description("parameter to test cs in strategy analyzer ")]
[Category("Parameters")]
public int Offset
{
get { return offset; }
set { offset = value; }
}

3. amend code to use Offset parameter...

if (orderId.Length == 0 && atmStrategyId.Length == 0
&& Close[0] > Open[0]+Offset )//test offset parameter in SA

4. optimize Offset parameter 1:2:1

5. SA does not make trades....because it does not process AtmStrategyCreate code

..............
in the case of my strategy, I had to add code to place trades in SA

such as ...

private IOrder entryOrder = null;

if ( StrategyAnalyzer == "on" ) { // Sets a trail stop of x ticks
SetTrailStop(CalculationMode.Ticks, StrategyAnalyzerTrail );
}

if ( StrategyAnalyzer == "on" && entryOrder == null )
entryOrder = EnterShort();


protected override void OnOrderUpdate(IOrder order)
{
if ( StrategyAnalyzer == "on" && entryOrder != null && entryOrder.Token == order.Token)
{
if (order.OrderState == OrderState.Filled)
entryOrder = null;
}
}

with this code I am able to place trades to test my entry triggers etc....I would be much happier if I could just use the AtmStrategyCreate code and also trail stops from my code...SA is very limited in this way

ATI User,

That is correct. SampleAtmStrategy and its concepts are not meant for backtesting and as such are not usable in the Strategy Analyzer. Here is a snippet from the AtmStrategyCreate() help guide article: "This method is not back testable and will not execute on historical data".

If you could mail in your replay files that would be great. josh [dot] peng [at] ninjatrader [dot] com. Thanks.

Thanks for reporting this issue. We will add it to the list of future considerations.
