Danger Real; Fear a Choice

Money management, or position sizing, is a critical component of trend following trading success: Consider wisdom from Ralph Vince:

You want the fewest moving parts (less parameters and less system rules) in your system. Primitive and simple grinding out profits over the long term. It’s not how profitable a system is, but rather that it is profitable. Money management takes the positive expectation, moneymaking system, and performs the real magic.
