comment How to find optimal look back in quant trading models
@user2763361 The OP is not referring to indicators as such but to lookback lenghts of indicators (this is even the title of the question). Furthermore he is not talking about models that work for multiple lookbacks (you made this up) but about optimising lookback periods in the range of very long and very short (he mentions that explicitly). A model will not be finalized until you haven't decided on all parameters used (lookback period being one of them). So at best you are addressing a completely different question.

comment How to find optimal look back in quant trading models
@user2763361: The only one who is talking about "variable selection" is you. Why should optimising other parameters (like lookback periods) be any better? And why should something that is a statistical problem in low frequency trading magically vanish in the HF domain?!?

Ok, will have a look - thank you for updating the post. Which parts do you think could be critical (where you are not sure whether this is the right way to do it)?

Now it runs - what is your exact question? Whether this replicates the algorithm described in the paper?
