My PnL Curve looks something like this since I started doing some changes into my trading. Below are some of them :

1) Shifting to larger timeframes.
2) Waiting patiently for the planned entry not the forced one.
3) Taking partial profits always, it lowers the stress.
4) Cutting losses earlier than profits.

Set time also for a trade to work, if it doesn't in that particular time range, then exit.
