My trade risk is 0,15% and I do not have a daily limits but at system level I have a halt limit in -20R (3%) and if that happens 3 times in a row I will throw the system to a trash can ;)
If Halt happens I have a "cool down" period of 1 week and then I have to do analyze process and only IF I can find the acceptable reasons for what happened I am able to take a new try.
