One of the great things about Options is you know exactly how much your Maximum Loss can be with every trade. You buy a Call for $400, and the most you can lose is $400. With a $20K account that trade risks 2% of your principal, and with a $10K account it risks 4% of your principal. But what about Total Account Risk? How many of these -2% or -4% trades should one have on at once? One ET Poster told me he only risks 10% of his principal at any one time. I'm currently risking 80% of my principal, but will be cutting that down to 50%. How does everyone else handle this?
