Thanks geektrader and footon for your input, I think I have an idea how to resolve this issue.
If Mr. Popov can add custom time frame for instruments, we can use data of 10seconds bar, as the matter of fact we do trade ticks not even 1 minute bars, this is complicity different approach, compare to MT4, as MT4 indicators attached to specific TF, but here in FSB you can adjust time frame in indicator itself (i know, it doesn't make sense if you read it only once , lol) , technically you can trade any time frame from tick data, in this case 10 sec TF (this won't be a big lug), just calculate MA taking into account that it is not 15M,30M, but 10Sec (multiple x-times, parameters).
Surely, it should be some adjustments made to accommodate this kind of accuracy, but if we do that, we are not limited by only last bar close.
there are some more sugestions, but I am not sure if MR. Popov, is willing to progress with this feedback.
1. Miti threading.
2. Cross validation
And a lot more.... Don't want to spend time if it is not taking into account.
I'll post strategy here , let's see if you think this will be FSB=FST. Much appreciated your feedback.
