Hi have same problem too & replying in this thread is self therapeutic to me.
But i figure out a way to control this emotion & also developed a philosophy on this. I might be wrong, but this is the only way to stop myself from getting into "Mad Zone".
I limit myself on the number of the trade I will make per day. So if cross the limit & made day loss, then I consider its not my day.
If I constantly win all trades & market is giving me a good trend, then I go further than my trade limit but with a protection. My extra trades are like free trades.
I count loss & profit not weekly but monthly. Most of the prop trading firms follows that.
End of the month I see myself where i'm standing.
Lastly risking less is blissful.
I see the point of the limits set - but remember the market has no boundaries so if it moves you have to fill your boots ................trading is about feast and famine.........markets don't understand the concept of averages ...it is us as traders that try to fetter those chains on it
I would try to set limits more within the rules of the system..........if you've messed up on x trades and losing hand over fist all the time that's not a problem solved by limits.....that needs a new system
