success rate is only one metric.
It must be considerred alongside how much you make when you are successful to how much you lose when trades do not work out.
As I have highlighted before. Its no good being right twice out of three if you make 1% when you are right and lose 10% when that one trade doesn't work out.
What is better is making more when the trades do work out and losing a lot less when they dont.
No one can be right 100% of the time trading or investing. it is impossible!
If you do not know how to manage or are unwilling to cut losses mercilessly, you will bleed yourself dry in this business. Possibly undoing many months or even years of work hoping that a bad trade will come good.
I have learnt this the hard way.
it is better to accept your loss early to protect your capital and have it free for the next opportunity.
Unrealized losses are still losses. Once your margin for error has been reached. cut and run.
