The Trading Metrics That Actually Matter (And What to Ignore)

Most traders obsess over their win rate. It's the first number they check after a week of trading, the one they quote when explaining their strategy, the one they use to judge whether they're improving.

Win rate is one of the least informative metrics in trading.

Why win rate misleads you

A trader with a 30% win rate can be consistently profitable. A trader with a 70% win rate can be losing money. The reason is simple: what matters isn't how often you win — it's how much you win versus how much you lose.

A strategy that wins 70% of the time but loses 3× its average winner on every losing trade has a negative expected value. You'll be right more often than you're wrong and still lose money.

Win rate becomes meaningful only when paired with risk-reward ratio. Which brings us to the first metric that actually matters.

The 5 metrics worth tracking

1. Expected value per trade

Expected value = (win rate × average win) − (loss rate × average loss)

This is the number that determines whether your strategy has an edge. A positive expected value means you make money over enough trades. A negative one means you lose, regardless of how good your setups look.

Calculate this monthly. If it's trending down, something in your execution or strategy has changed.

2. Average risk-reward ratio

Not the planned R:R from your system — the actual R:R from your closed trades. The difference between these two numbers tells you about your execution quality.

If you plan for 2:1 trades and your actual average is 1.2:1, you're either moving stops too early, taking profit too soon, or both.

3. Expectancy by emotional state

This is where most traders' data gets interesting — and uncomfortable. Separate your trades by the emotional state you recorded at entry. Calculate win rate and average P&L for each category.

The pattern is almost universal: trades entered in calm or confident states significantly outperform trades entered in FOMO, anxious, or revenge states — even when the setups look identical.

4. Performance by time of day and day of week

Markets have personality at different times. More importantly, you have personality at different times. Your ability to execute your plan may be systematically better at 10am than at 3pm, or on Tuesdays than on Fridays.

This isn't superstition — it's data. And once you have it, acting on it is simple: trade more during your high-performance windows, reduce size or stop trading entirely during low-performance ones.

5. Maximum drawdown and drawdown duration

Peak-to-trough drawdown tells you the worst period your account has experienced. Drawdown duration tells you how long it took to recover.

Both matter for position sizing and risk management. A strategy with a 20% maximum drawdown requires you to have the psychological tolerance — and the account size — to survive it without making decisions that make it worse.

The 3 metrics that mislead you

1. Win rate in isolation

Already covered. A 60% win rate with 1:3 average R:R (wins are ⅓ the size of losses) is a losing strategy. A 40% win rate with 3:1 average R:R is a profitable one.

2. Gross P&L without trade count context

"I made £2,000 this month" means nothing without knowing how many trades you took and what risk you deployed. If you took 80 trades to make £2,000 with an average risk of £200 per trade, that's a poor result. If you took 10 trades with an average risk of £100, it's excellent.

3. Recent performance as a trend

Three winning weeks in a row doesn't mean your edge has improved. Three losing weeks in a row doesn't mean your edge has disappeared. Trading has variance — short-term results tell you less than you think.

Meaningful performance trends require at minimum 50–100 trades to start being statistically reliable. Judge your system over months, not weeks.

Making metrics work for you

The problem isn't calculating these numbers — it's that most traders don't have clean data to calculate them from.

You need a record of every trade with: entry reason, emotional state, planned R:R, actual outcome. Without that, you're calculating averages across an undefined mixture of planned trades and impulsive ones — and the numbers won't tell you what to fix.

The discipline of tracking is what makes the analysis possible. The analysis is what makes the improvement real.
