How many of you out there who have been trading for some time, have some kind of edge they know they can exploit day in, day out, which makes them generally or even extraordinarily profitable, and have confidence that they can continue earning profits almost each and every day -- how many of you in this category still go through that periodic day of destructive trading resulting in a huge drawdown (compared to your profitable days) simply because you can't stand dealing with a broken string of steady gains? I'm not quite there yet to able to say I have that confidence in knowing I can produce steady profits each day, which is perhaps why I still encounter big drawdowns every so often -- almost always coming after a winning streak. It seems that continued success will breed a kind of pride which makes accepting even small losses difficult, which can result in overtrading, overleverage, unreasonable profit targets to "make it back" etc. What's the best way to combat this habit if one trades without the benefit of automatic risk management precautions? Some ideas are: reducing position sizes after every loss, or shutting off screen after a max loss/day is reached -- yet it just begs the question if one's psychology can actually apply these rules when the problem is a seemingly irrational response to losses in the first place. Thoughts?
