    Help!Test result total different from the same strategy.


    I met a very weird issue.I built strategy yesterday,by strategy builder,and it test well yesterday and this morning.And I have saved it in strategy builder.

    But just now,while I load the same strategy,it give very different result!!!

    My test period is from 6.23-7.23 2019 2018 2017 2016.

    Do any body else met this issue before?

    Please help!!!

    Hello williamzz,

    Thank you for the post.

    It is certainly possible that a strategy will perform differently from day to day depending on the logic you are using. There is not really enough information here to provide any kind of more detailed answer other than this is possible. To know why the result was different would require you to look at the executions and also may require that you explore how your logic was executed in each situation. Looking at the executions should be a first step to see where the two tests deviate. After this you may need to look at how the conditions occurred in each test to understand the problem in more detail.


    I look forward to being of further assistance.

        Hello williamzz,

        What data are you trying to retrieve? There is no backup of your NinjaScript data unless you make a backup of it yourself. If you made changes to your strategy, you would need to remember what changes you made and then undo them.

        If you are trying to look at the past backtests, you can look in the log in the analyzer for those by right clicking and selecting view log.



        I look forward to being of further assistance.
