Strategy Analyzer Stoppped Working

[sdauteuil]

The strategy analyzer stopped returning results - related to date ranges

example

If I run an optimization from 9/27/2018 to 1/31/2019 no results are returned. If I change the dates to 9/24/18 to 1/30/19 results are produced. It is an intraday strategy with same exact entry so changing the dates shouldn't affect the results certainly not causing it to create no results.

This has happened in the past on 2 different computers. Usually I can close and re-open the strategy analyzer and or restart the computer and that fixes the problem but that is not working now.

I see this error in the log file I do not know if this has any relation. Log attached

2019-08-23 08:38:28:075|3|4|Strategy 'TweezerTopTrailSE': Error on calling 'OnBarUpdate' method on bar 19: You are accessing an index with a value that is invalid since it is out-of-range. I.E. accessing a series [barsAgo] with a value of 5 when there are only 4 bars on the chart.

I have a lifetime license but this is on a second computer with the free license. It has happened on both computers.

Thank you for any help Stefan

Hello sdauteuil,

The error would be related if that is being presented when you see this 0 result test. Any error your script encounters will completely stop the test, if it is seeing an OnBarUpdate error that needs to be corrected before the test will produce results.

Based on the situation it sounds like this could relate to data, are you adding any secondary series in the script?

You very likely need a CurrentBar check in the script but that will depend on what series were used and what BarsAgo have been used.


I look forward to being of further assistance.

Primary time frame is 50 ticks there is a secondary time frame referencing previous days high.

However this has happened in the past on scripts without secondary time frame references. Is it possible something is getting trapped in the computer memory or cache? I am not a computer guy just wondering because of the previous fixes when restarting the computer and or strategy analyzer.

The strategy is built from the strategy builder.

I see this code in the script

** Secondary data series defined
AddDataSeries(Data.BarsPeriodType.Day, 1
**

protected override void OnBarUpdate()
{
if (BarsInProgress != 0)
return;

if (CurrentBars[0] < 1)
return;

I also tried changing the bars required to trade in the strategy analyzer, that had no effect.

Hello

[I]However this has happened in the past on scripts without secondary time frame references.[/I]

Correct, when adding multiple series you can run into this error if the script is programmed in a way which allows for that to happen. This can also happen for single series scripts depending on the syntax.

Can you provide more detail on how the secondary series is being used in your conditions?

[I] Is it possible something is getting trapped in the computer memory or cache? I am not a computer guy just wondering because of the previous fixes when restarting the computer and or strategy analyzer.[/I]

Based on the error presented that would relate to your logic not memory or cache. It is very likely some way that the scripts logic is formed which is contributing to this. I would need to see the conditions created to better understand why you might see this error. Can you provide an image of the conditions where you used the secondary series?

Also, you provided syntax but noted you are using the builder, have you unlocked the code or was this just to show the second series being used? if you unlocked the code, I would just need to see the code and we can ignore the builder images.


I look forward to being of further assistance.

Here is the code. I also attached a locked and unlocked file. I would like to keep it in the locked strategy builder if possible but if it needs to be unlocked to be fixed... Whatever works

Thanks again

I tried to post the code in the text and attach the strategy files but the post gets stuck "pending".

Here are the script files locked an unlocked. I would like to keep it in the strategy builder if possible but whatever works.

I can try to repost the code in the text if you would like.

[NinjaTrader_Jesse]

Hello sdauteuil ,

Thank you for providing the files,

From what I can tell, it is related the following line:

&& (Close[0] < Highs[1][0])

This syntax is using the secondary series, we need a CurrentBars check because of this to make sure that series has data. I see that the locked strategy has the check but your unlocked version does not have the full check so that is one item to change.

Can you test the following from your end? I was getting the error but no longer seem to be able to hit it after trying some changes, reverting back I am still not seeing it so this may be quicker for you to also test this.

Make a new duplicate of the builder strategy and unlock it so all code is identical again

Change the following:

if (CurrentBars[0] < 1
            || CurrentBars[1] < 0)

to

if (CurrentBars[0] < 1
            || CurrentBars[1] [B]< 1[/B])

Then retest, do you still see the error?

The only difference is that this makes sure both series have 1 bar before processing and not that the primary has a bar and secondary is loaded.


I look forward to being of further assistance.

[sdauteuil]

I only saw the code

if (CurrentBars[0] < 1 ** I did not see that second line of code

I did change it to

if (CurrentBars[0] < 1
|| CurrentBars[1]<1)

That seems to be working... I will give it some additional testing as I have seen this correct itself and start causing the same error.

What does the double vertical line stand for?

[NinjaTrader_Jesse]

Hello sdauteuil,

Yes in one of your scripts that syntax is not present, if you duplicated the script before adding the second series that would have been added later. The double pipes || means OR, if CurrentBars[0] < 1 OR CurrentBars[1] < 1

I will provide this information to development as well, if you created the strategy with the builder this type of error is not generally expected and is not something you should need to manually edit.
