====== Multi Market ======

The Multi Market tool can help you compare how your strategy performs in different markets. In a sense, this is a robustness testing tool. Here you can add markets to test your strategy on. When you start the Multi Market, EA Studio will load the corresponding data files and will calculate the strategy on all of the selected markets.

The tool validates the backtest results according to the own Validation criteria, draws all balance lines in a chart and collects the most important performance parameters in a table.

The fastest way to find strategies, which validates on several markets is to use the [[eas-guide:reactor|Reactor]]. You can run it with the Multi Market option switched on. Then, it will validate all generated strategies against the selected markets. You will be sure all passed strategies in the Collection correspond to the Multi Market criteria.
