-50%
Leave the match when you are -50 % is an option for a stop loss system.
Recovery point
This is a subject that im still developing in my trading and studing but i think i can tell you the main idea. If you do a freestyle trading (different strategies at different times) its very benefic to search for your max point to recover your red. I'll give you one example.
For example:
Imagine that you trade for a long time and you decide to improve your stop loss system(imagine its the "leave when -50%").
For every match you start to record the biggest red you had at some point of the match and the final result that can be the biggest red or some other result and the max red you can have for the match is -50 %.
Imagine that you trade one match and in the end of the first set you are with -30% and in the end of the second set you have -10%. You have to record these variables. - 30 % is the point of recover.
After one month(more time to study -> better) you will check your best point of recover, that is basically the last point where you will have a chance to recover and if your red raises above that limit you get out of the match. You can apply math to choose the best point. In the long run this will probably save a lot of money.
Just one idea that you can start applying.
