Many of us have often wanted to see in a visual way where a certain trading strategy has its flaws. And if we could see the objective trading statistics at the same time it would be really great.
There is a backtester in MT4 but running a backtest in a visual mode for each change in the EA takes a lot of time. Also, its visual capabilities are quite limited. Then, you cannot test multi-currency strategies with it, at least not in an efficient way.
I have tried to address all of these issues and the result is this open-source indicator for visually testing trading strategies. Of course it is not possible to make a completely universal indicator for all the purposes but the current framework can be easily modified and expanded for specific needs (like multi-currency).
