Hello Charbel,
This is called grid trading.
The indicators are created to watch the current market conditions, and not to look for the previous entry. The market doesn’t care about our previous entries. I know this idea of averaging but it is more of investing type of trading which some traders try to convert. I am not familiar with a successful one( I don’t say there isn’t one).
The trading is more oriented to trading at the moment, according to the recent market conditions. And this is what the indicators are used for. This is why there is no such method or indicator in MT or FSB and EA Studio.
Yes, you can modify the entry in the code but this way you will not have a backtest in FSB Pro which is the main idea of having a strategy builder. To have the past results and analyze it.
I hope this makes sense.
