Focus is the key toward success. Martin Schwartz always is my model. since I had the similar styles. I once shorted 20lots of sweet crude in the drop, and immeadiately closed with $0.1 gain, just $0.02 away from the true bottom,and that bottom price actually just stays seconds!
I donot believe in theory/plans. I beleieve in instincts. That open minds lot. when I thought and observed too long, always I got some dummy ideas, often it is costy. The theory/ideas hold me to act naturally.
My costly story is when I read a book about reaction/pullback, the market is rallying, then reacting/pullingback, volume dries up, that is a good time to buy, after I read that, my mind is occupied by this dummy idea. one time, every signs which is described in this book is there, I bought a pullback, but it keeps edging down. my belief drove me nuts! Normally I cut loss and move on without any issue, but that book's idea made me hold on to a loser too long.
