Walk Forward Optimization is an optimization process that addresses the issue of curve fitting in strategy development.
Walk Forward Optimization segregates the data series into multiple segments, and each segment is divided into an in-sample (IS) portion and an out-of-sample (OOS) portion.
Parameter optimization for the strategy is performed using the IS portion of the first segment. The same parameters are then used to back test the strategy on the OOS portion of the same segment. The process is repeated for the remaining segments.
The OOS performance results from each of the segments are considered "real" instead of "curve-fit" because the parameters that produced the OOS results were generated from IS data.

It shouldn't be too hard once we're launched the optimization features. Will keep it in mind for the planning. If you have other feature requests please file them in github - https://github.com/QuantConnect/Lean/issues

Also curious on the status. It would definitely be something worth paying more for!

Sorry to bring up an old thread, but was walk forward optimization added? Is there way to make your own optimizer in python or only through contributing to the git repo? Thanks!

Officially scheduled for 2023. We're currently cranking through bugs but will hopefully get to features soon.
We're hiring for LEAN C#/C++ Engineer if anyone is interested in doing this full-time!
