Bend over and spread your cheeks. Apply some lube and just let Mr Market have his way with you In other words go with the flow. Losses and losing streaks are a natural part of trading.
I've learned something in my "losing streaks". And I now have only 100% winning streaks. It is the most inefficient way to trade...EVER, but it works for me at this time. One of these days, you will find your way as well.
You define the number of losing trades that you consider a streak in advance and just stop trading when loss count hits this number.
OP, I'd listen to Overnight if I were you. He is the MASTER of this subject. He has soooo much experience in this regard. Good luck!
