 The final goal of the tool is to provide strategies that have passed all robustness tests. So we can start EA Studio for a night and we will have ready for trading strategies set at the morning. The final goal of the tool is to provide strategies that have passed all robustness tests.

-==== Walk Forward ==== +==== 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. **Walk Forward analysis (WFA) or Walk Forward optimization (WFO)** is a sequential optimization applied to an investment strategy.

-===== Monte Carlo Validation =====+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.

 +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.

 We have 6 markets on the example above and the validation threshold is 3. That means that if 3 or more tests finish on profit, the strategy will ascend to the Collection. We have 6 markets on the example above and the validation threshold is 3.

 +==== Hint for Reactor / Validator ==== 
 +It is best to use only one of the following tools:
 +  * Full Data optimization
 +  * Walk Forward optimization
 +  * Walk Forward validation
