Strategy Analyzer

[designer01]

Is there a way to preview the number of iterations to optimize a strategy in Strategy Analyzer prior to click the Run button? Sometimes if it comes to too many NT crashes and have to restart everything. Thanks.

Hello designer01,

Thank you for your note.

There is not a way to preview the number of iterations before running an optimization, however this is not the only item that affects the performance and resource usage of the Strategy Analyzer. I recommend reviewing the following information in our help guide about factors that affect optimization performance:

The following post also includes additional information regarding optimization performance and ways to improve the performance:

Please let us know if we may be of further assistance.

Hello Emily,
It is good to know how many iterations the optimization will take in order to have an idea of the time it will take to perform the optimization. I try to keep it under certain number which I would like to know before clicking Run. Could this feature be added in future updates? Thanks

Hello designer01,

Thank you for the suggestion.

I have submitted this as a feature request to the Development Team. I will follow up with an internal tracking number for your reference as soon as it is created.

Thanks in advance for your patience.

I made that request some time back. Is "SFT-4476" a new feature request for this same issue ?

Hello spottysallrite,

Thank you for your note.

I advised to designer01 that their vote was added to an existing feature request, so no SFT-4476 is not a new feature request. That being said, I looked at the votes for SFT-4476 and found that your vote is being tracked under the same number. Please see your thread with NinjaTrader_Kate from 2/15/2022 here where she advised that your vote was also added to SFT-4476:

In the future, I recommend taking note of the tracking numbers provided to you for feature requests you have opened or had a vote added to. This can help to prevent confusion and you can always reference the tracking number when contacting support about the feature requests you have expressed interest in.

Thank you for your patience.

Sorry, I must not have seen your note to designer01 on 1/17, "Your vote has been added to an existing feature request."

Anyway, as an extension on this idea, would it be possible to include the number of processors being used to calc the optimization time? That is, the current display / calc time assumes only one processor. I would think most of us have several processors. eg, if you have 3 variables, and want each to use a range of 4 values, that would be 12 combinations (ie, 3 x 4). If your machine has 2 cores, then there would be 6 "blocks" of iterations (ie, 12 / 2). Multiplying the number of blocks by the individual backtest time (eg, 4 minutes) would then produce the actual, overall optimization time (eg, 6 x 4 = 24 minutes).
