The number of trades required to feel confident in a trading strategy varies per individual, with examples ranging from 100 to 500 trades, and a 65% win rate being a potential benchmark for confidence.
"How many trades would it take you to be confident in a strategy? How many trades do you need to test? Is it 100? Is it a thousand? At what point do you go, 'Okay, I've tested 500 trades now, and I've seen that throughout these 500 trades, I still have a 65% chance of winning with this strategy. Does that make you confident, or do you only need a hundred?'"
