Normalized Profit Factor

Here my first share.

Seen it and coded from the article here :
mastering-the-art-of-trading-metrics-an-interview-with-bozhidar-bozhkov-on-normalised-profit-factor

Summary :

1. It works even when profits or losses are zero.
2. It gives a result between -1 and 1, which is easier to interpret.
3. It takes into account both the magnitude and direction of profits and losses.

Ps : Let me know if there are any mistakes

Note – there is an updated version for SQX Build 140 and above (update done by SQX team)
