Why a High Win Rate Can Hide a Losing Trading Strategy

A trader wins 80% of their trades.

Another wins only 40%.

Who is more profitable?

Most beginners would choose the first trader.

But professional investors know that win rate alone reveals very little about a strategy’s profitability.

What matters is the relationship between average gains, average losses, and execution costs.

Consider two strategies over 100 trades.

Strategy A wins 80 trades, earning $20 on each winner, but loses $100 on each of its 20 losing trades.

Total gains: $1,600.

Total losses: $2,000.

Net result: -$400 before fees.

Strategy B wins 40 trades, earning $100 on each winner, while losing $40 on each of its 60 losing trades.

Total gains: $4,000.

Total losses: $2,400.

Net result: +$1,600 before fees.

The strategy with the lower win rate produces the stronger outcome.

Now consider transaction costs.

At an illustrative 0.10% Spot commission, $200,000 in cumulative trading volume generates $200 in fees.

A qualifying 20% discount would reduce that amount to $160.

But lower commissions cannot turn poor risk management into a reliable advantage.

Professional traders focus on expectancy, not simply accuracy.

A strategy doesn’t need to win most of the time.

It needs its profitable outcomes to outweigh its losses and costs over a meaningful number of trades.

In trading, being right frequently matters less than being profitable consistently.
