Hi,
is there an article that explains how to use walk-forward optimization in QS ? I couldn't find it.

Also, is there a way to combine AI Optimizations with walk-forward ?

Thanks !

You can find many articles on the web on how the walk-forward optimization works. It doesn't work with AI Optimizations.

I'm familiar with the concept of walk-forward testing. It's not clear to me how to use it in QS.
If I want to test a time period from 1995 to 2015, using the usual 80/20 distribution, not anchoring the initial date, how do I do this in QS ? What is Step period ? Use today ?

Could you please illustrate with an example ?

Thanks,

When you click on the Walk forward, all you have to do is select the start/end period and the step period for the in-sample tests and the out-of-sample period. There is a tooltip that appears when you click on the "Step Period" input box. The step period is used to move the start/end period. On the right you can see the different in-sample and out-of-sample periods that results from your settings.
