This is really frustrating. Just got out of a painful trade. I thought I was starting to make sense of this and then, bam, there goes $15,000 right before Christmas. I haven't made a penny this year and I've been much more disciplined. Really wish I didn't have to keep paying market tuition. How does one handle this kind of disappointment?
Every time you are about hit the "BUY" button, first identify where you will place your stop. Then assume the trade will be a loser and ask yourself "am I comfortable with the amount of money I am about to lose on this trade?" If you answer is "no" then you must reduce your position size until the potential loss is small enough where your answer is "yes, I am comfortable with losing this amount of money." Besides that, make sure you go home flat every single day, that way you will be protected from losing more than you intended during overnight/weekend gaps.
