Improve STATISTICS, add the MAE / MFE data

I feel the stadistics module is not very clear and lacks data as MAE / MFE

MAE stands for Maximum Adverse Excursion

MAE marks the lowest price during a long trade and the highest price during a short trade. This helps you to identify what the maximum loss was during a trade. This is also known as maximum drawdown of the position.

MFE stands for Maximum Favorable Excursion.

MFE marks the highest price during a long trade and the lowest price during a short trade. This shows you what the highest profit was during a trade.
