Whenever I enter a position, I have a predetermined stop. That is the only way I can sleep. I know where I'm getting out before I get in. The position size on a trade is determined by the stop, and the stop is determined on a technical basis... I never think about [stop vulnerability], because the point about a technical barrier - and I've studied the technical aspects of the market for a long time - is that the market shouldn't go there if you are right.
Bruce KovnerMy experience with novice traders is that they trade three to five times too big. They are taking 5 to 10 percent risks on a trade when they should be taking 1 to 2 percent risks. The emotional burden of trading is substantial; on any given day, I could lose millions of dollars. If you personalize these losses, you canโt trade.
