Flexible EA works by loading your custom indicators into the EA to trigger Buy/Sell signals and TP/SL signals, it also has a built-in advanced grid, averaging, trailing, and filtering systems.
Many times it happened that you grabbed a nice indicator and sat watching its beautiful blue and red arrows or dots popping up on your chart indicating buy/sell signals that you only wished if you can backtest this indicator to see it's performance.
Well this happened to all of us and many many times. On top we all wasted money creating EAs just to be able to backtest a heroic indicator which ends up being a total loser.
Here comes Flexible EA, just fill in your custom indicator's name and run a backtest, you can endlessly backtest the 10's or 100's of indicators that you have lying around, you can even auto trade with Flexible EA, it comes loaded with many features.
