Best Trading Metrics Every Serious Trader Should Track

You cannot improve what you do not measure. These are the eight trading metrics every serious trader tracks — with the formula for each, why it matters, and how to use it to sharpen your edge.

1. Win Rate

Percentage of trades that closed positive. Meaningful only alongside R:R. A 40% win rate at 1:3 R:R is excellent; a 70% win rate at 1:0.3 R:R is a losing system.

2. Average R Multiple

R = trade P/L ÷ initial risk. An R of +2 means the trade made twice your risk. R normalises trades across sizes so you can compare a $100 win and a $10,000 win on equal footing.

3. Expectancy

Expectancy = (Win rate × Avg win) − (Loss rate × Avg loss). The average dollars you make per trade. Multiply by trade frequency for monthly income. Compute yours in the Expectancy Calculator.

4. Profit Factor

Gross profit ÷ Gross loss. Above 1.5 = solid. Above 2.0 = excellent. Below 1.0 = the system loses money.

5. Maximum Drawdown

Largest peak-to-trough decline in equity. If max drawdown exceeds 20%, sizing is too aggressive. See the Drawdown Recovery Calculator for the asymmetric recovery cost.

6. Sharpe / Return-to-Drawdown Ratio

Sharpe = (annual return − risk-free rate) ÷ annual return volatility. Simpler alternative for traders: return ÷ max drawdown. Aim for at least 2 (annual profit is 2× the worst drawdown).

7. MAE / MFE (Maximum Adverse / Favourable Excursion)

MAE = the biggest paper loss during a trade before it closed. MFE = the biggest paper gain. Comparing MFE against your actual exit tells you if you leave money on the table. Comparing MAE against your stop tells you if your stops are wider than they need to be.

8. Edge Decay

Rolling win rate + expectancy over the last 30 trades vs last 100 trades. If the recent window is materially worse, your edge is decaying — market regime probably shifted.

How to Track These Without Losing Your Mind

1. Journal every trade (see the trading journal guide).
2. Export to a spreadsheet monthly.
3. Calculate the eight metrics.
4. Kill any setup with negative expectancy over 30+ trades.
5. Track edge decay every quarter — regime shifts are real.

Common Mistakes

• Only tracking P/L — you cannot improve what you cannot decompose.
• Small sample sizes — 20 trades is not enough to trust any of these numbers.
• Ignoring rule-adherence — great metrics with 60% adherence is luck, not skill.
• Chasing metrics with regime-specific data — a bull-market system will look great in bull markets.
• Confusing profit factor with expectancy — profit factor can be 1.5 while expectancy is $0 if you never trade.

FAQs

Which metric is the most important?

Expectancy per trade. Everything else is diagnostic.

How often should I compute metrics?

Weekly for eyeballing, monthly for hard decisions, quarterly for strategy changes.

Do these apply to buy-and-hold investing?

Sharpe, drawdown and profit factor yes. Win rate and R multiple less so.

Are automated dashboards worth it?

Once you have >200 trades, yes. Tools like TraderVue and Edgewonk auto-compute these.

Key Takeaways

• Win rate + R multiple = expectancy. Track all three.
• Profit factor and Sharpe give a portfolio-level view.
• MAE / MFE tell you if your entries and exits are efficient.
• Edge decay is real — check quarterly.
• Rule-adherence >90% is a metric in itself.
