    Most recently when running a WFM test, and the process just ultimately never finishes.

     

    Any ideas?

    Do you know what setup leads to this error or do you get it just randomly?

    Hi Tomas,

     

    Seems random…doesn’t always happen.

    I have sent Mark 4 emails since Thursday in regards to the same Error that Is mentioned above when I try to use the WFO Forward Matrix. I HAVE RECEIVED NOT ONE RESPONSE BACK??? I’m also a potential new customer as I’m considering buying SQ which baffles me as I would think as a potential buyer I would be a priority especially when I’m testing out the product which I might buy that I’m receiving a major error???

    As a business your most valuable asset isn’t your software or product’ you develop but instead are your clients, as with out clients especially potentially new ones(such as myself) you wont have a business to operate. Can you please advise as to the error below.

    I’m using settings that I previously used with WFO which I didn’t receive the error back then but for some reason now I get the error when it’s done running it’s tests. Out Of Sample% 20/30 step by 5. Walk Forward Runs 4/15 step by 5 Parameter settings are fine, previously used with no error, optimizing two indicator settings and then Sl, TP,Time Ranges ect.. Instead of using the “Simulated” option which gives me the error. I’m going to try and use the “Exact” option and see if I get an error at the end again.

    I’ve had the same problem in WF run with Out of Sample (20 / 50 / 10) and run (5 /14 /3) do you have any solution?
