Hi everyone,

Is backtest necessary before WFA, or is it just a waste of time? Considering the fact that WFA will test the strategy’s robustness and estimate its real time performance better, do you guys do backtests before WFA, or just put a strategy to test with WFA?

WFA:


Done only with historical data. Not with live data.

Backtest:
Using all or part of historical data without any out-of-sample testing.

Thanks.
