You Don’t Need to Be Right to Make Money... You Just Need a Good Trading System

Adrian Reid explains that successful active trading depends less on being right and more on having a good, rule-based trading system applied across a diversified portfolio. Key advice: "if in doubt, zoom out" (use longer timeframes), avoid concentrating on a single holding, trade many instruments with the same rules, keep losses small and let winners run. He gives a numerical example showing profitability even when wrong most of the time: out of 10 trades, if wrong 7 times losing $1 each and right 3 times gaining $5 each (total +$8), the system is profitable. Reid notes his own experience over ~20 years with a high loss rate but net gains due to position sizing and letting winners be large.
