The Problem

Most traders lose because
of poor risk management.

Not because of bad entries. Not because of the wrong strategy. Because they're risking too much, too often, with no system.

I blew my account in two trades because I didn't know how to size my positions correctly.

I was profitable on direction but still losing money — I had no idea what lot size to use.

I kept risking random amounts each trade. Some too big, some too small. No consistency.

Every time I calculated manually I made errors. It cost me real money on real trades.
