Every trader has opinions. About the market, about their strategy, about whether today is a trading day or a beach day. But opinions do not pay the bills. Numbers do. And the right numbers, tracked consistently, are the difference between a trader who builds wealth and a trader who donates it to the market one tick at a time.
The problem is not a lack of metrics. The problem is too many. Open any trading analytics platform and you will see fifty different numbers staring back at you. Most of them are noise. A handful of them are signal. This guide cuts through the clutter and shows you exactly which metrics matter, why they matter, and how to use them to actually improve your trading.

Win Rate: The Starting Line, Not the Finish
Win rate is the percentage of your trades that close in profit. It is the first metric every trader learns, and the first metric every trader misunderstands. A 90% win rate sounds amazing until you realise that the 10% of losers are five times larger than the winners. Suddenly that 90% win rate is a losing strategy.
Win rate on its own tells you almost nothing about profitability. It needs context. That context comes from your risk reward ratio and your average win size versus average loss size. A strategy with a 40% win rate can be wildly profitable if the winners are three times larger than the losers. And a strategy with an 80% win rate can bleed money if the occasional loser wipes out weeks of gains.
What Good Win Rates Look Like
There is no universal "good" win rate. It depends entirely on your strategy type. Trend following systems typically run 30 to 45% win rates with large winners. Mean reversion and scalping systems often run 60 to 80% with tighter risk reward. The key is understanding what your strategy should produce and tracking whether it actually does.

Profit Factor: The Single Number That Matters Most
If you could only track one metric, profit factor would be a strong candidate. It is your gross profits divided by your gross losses. A profit factor of 1.0 means you are breaking even. Above 1.0 means you are making money. Below 1.0 means you are losing it.
A profit factor of 1.5 means you make $1.50 for every $1.00 you lose. That is a solid edge. A profit factor of 2.0 or above is excellent. Anything below 1.2 means your edge is thin and commission costs or a few bad trades could flip you negative.
| Profit Factor | Interpretation | Action |
|---|---|---|
| Below 0.8 | Significant losses, strategy is bleeding | Stop trading this strategy and review |
| 0.8 to 1.0 | Losing money but close to breakeven | Identify what is dragging it down |
| 1.0 to 1.2 | Marginal edge, easily eroded by costs | Optimise entries, exits and costs |
| 1.2 to 1.5 | Decent edge, worth running | Monitor and protect |
| 1.5 to 2.0 | Strong edge, allocate more capital | Scale carefully |
| Above 2.0 | Excellent performance | Verify with enough sample size |

Get Started FreeMaximum Drawdown: The Pain Metric
Maximum drawdown measures the largest peak to trough decline in your account equity. It is the metric that tells you how much pain you need to stomach to earn your returns. And it is the metric that kills traders who ignore it.
A strategy that returns 50% annually sounds incredible until you discover it had a 40% maximum drawdown along the way. That means at some point, your $100,000 account dropped to $60,000 before recovering. Most traders cannot sit through that. They quit, switch strategies, or worse, double down at the worst possible time.
Drawdown Recovery Math
Here is why drawdown matters more than most traders realise. The recovery is not symmetrical. A 20% drawdown needs a 25% gain to recover. A 50% drawdown needs a 100% gain. A 75% drawdown needs a 300% gain. The deeper the hole, the exponentially harder it is to climb out.
| Drawdown | Recovery Needed | Reality Check |
|---|---|---|
| 10% | 11.1% | Manageable, normal trading |
| 20% | 25% | Starting to hurt, need discipline |
| 30% | 42.9% | Serious. Review strategy viability |
| 40% | 66.7% | Critical. Most traders quit here |
| 50% | 100% | Need to double your money just to break even |
| 75% | 300% | Account is effectively destroyed |
ACE Portfolio Tracker monitors drawdown in real time across every strategy. Traffic light indicators warn you before you hit dangerous levels. Get the full guide at Drawdown Explained.
Risk Reward Ratio: The Architecture of Edge
Risk reward ratio compares your average winning trade size to your average losing trade size. If your average winner is $300 and your average loser is $150, your risk reward ratio is 2:1. You make twice as much when you win as you lose when you are wrong.
This metric is the architectural backbone of your strategy. Combined with win rate, it determines whether you have a mathematical edge. A 2:1 risk reward with a 40% win rate is profitable. A 1:1 risk reward with a 55% win rate is profitable. A 0.5:1 risk reward needs a 70%+ win rate just to break even.

Expectancy: Your Edge, Quantified
Expectancy tells you how much you should expect to make on average per trade over a large sample. It combines win rate, average win size and average loss size into a single number. Positive expectancy means you have an edge. Negative expectancy means you do not.
The formula is simple: (Win Rate x Average Win) minus (Loss Rate x Average Loss). If your win rate is 45%, your average win is $500 and your average loss is $250, your expectancy is (0.45 x $500) minus (0.55 x $250) = $225 minus $137.50 = $87.50 per trade.
That $87.50 is your edge per trade. Multiply it by the number of trades you take per month and you have your expected monthly income from that strategy. This is the number that turns trading from gambling into a business. See the full breakdown at Expectancy and Edge in Trading.
Turn Your Trading Chaos Into a Scoreboard
Every metric calculated automatically. Win rate, profit factor, drawdown, expectancy, Sharpe. All of it. Across every strategy.
Start Free TrialSharpe Ratio: Risk Adjusted Returns
Sharpe ratio measures how much return you get for each unit of risk you take. A high return with wild volatility might have a lower Sharpe than a modest return with smooth, consistent growth. The higher the Sharpe, the better the risk adjusted performance.
A Sharpe ratio above 1.0 is generally considered acceptable. Above 2.0 is very good. Above 3.0 is exceptional. Below 1.0 suggests you are not being compensated enough for the risk you are taking. This matters enormously when comparing strategies because it normalises for risk.
ACE Portfolio Tracker calculates Sharpe ratio automatically for every strategy and every portfolio combination, making it easy to compare strategies side by side on a risk adjusted basis.
Consistency Score: Separating Luck from Skill
Consistency measures how stable your returns are over time. A strategy that makes $1,000 per month every month has high consistency. A strategy that makes $10,000 one month and loses $8,000 the next has low consistency, even if the total P&L is positive.
Consistency matters because it predicts survivability. Consistent strategies are easier to trust, easier to stick with, and easier to allocate capital to. Inconsistent strategies lead to second guessing, overriding signals, and emotional trading mistakes that compound the problem. Track your trading discipline alongside consistency to see the connection.
How Metrics Work Together
No metric works in isolation. The magic happens when you read them together. Here are the combinations that tell the real story.
| Combination | What It Tells You |
|---|---|
| High win rate + low risk reward | Scalping style. Works if costs are low. Fragile. |
| Low win rate + high risk reward | Trend following. Needs patience and discipline. |
| High profit factor + high drawdown | Profitable but painful. Can you stomach the dips? |
| High Sharpe + low drawdown | The holy grail. Smooth, consistent, risk adjusted returns. |
| Positive expectancy + high consistency | This is a strategy worth scaling. |
| Good metrics + declining equity curve | Edge might be fading. Time to review. |
ACE Portfolio Tracker shows all these metrics on a single dashboard so you can read the full story at a glance. Combine with the equity curve analysis tools and you have the complete picture.
