If I can stop trading for even one day after a 10% loss that would be a new milestone for me.
This is a terrible idea. What happens is, you get paralyzed after a 10% loss. You become so paralyzed, you do not enter a new trade until you see that the 10% loss could have been made back if you had gone back in.
By the time you get back in? You see another 10% loss. The cycle perpetuates itself.
