 +==== Walk Forward optimization ====
 +
 +**Walk Forward analysis (WFA) or Walk Forward optimization (WFO)** is a sequential optimization applied to an investment strategy. The name of the analysis is called “walk forward” because we have a moving window that progressively traverses the whole period of the data history with a pre-established step. Algorithmic traders apply such analysis to decrease the over-optimized parameters used in the investment strategy as we don’t want only a great looking backtest result, we want also a system that don't fail in live real money account.

 +In the "Reactor" context this optimization works if the strategy perform better than the original strategy (full data backtest vs full out of sample walk forward results) the last parameters will be accepted and the original strategy will be replaced with.

 With the previous tools you could check if the strategy is still profitable and attempt to make it more profitable. The tools below have a different goal. The robustness testing tools let you analyze how trustworthy a strategy is. This step is very important. With the previous tools you could check if the strategy is still profitable and attempt to make it more profitable. The tools below have a different goal.

 +==== Walk Forward validation ====
 +You can use WFO as validation tool and it returns only strategies that pass the validated segments without changing the original parameters of the strategy.
