It breaks with convention but in trading its okay to be a pessimist.

I’m not saying procrastinate. Far from it. All I suggest is that when you see your buy (or short) opportunity don’t picture the pound signs increasing. Don’t see the share going in the direction you’re hoping.

Instead, see it reversing, doing the opposite. See it stopped out.

About half the time, even for professional traders, it will anyway.

This simple twist in thinking helps decide the amount you risk.
