Understanding Performance Analytics
Learn how Trader Diary calculates and displays your trading performance metrics.
Overview
Trader Diary automatically calculates comprehensive performance metrics from every trade you log. These metrics help you understand not just whether you're profitable, but why and how consistently. All metrics update in real-time as you add or modify trades.
Core Performance Metrics
Win Rate
Definition: The percentage of trades that result in a profit (excluding wash trades).
Calculation: (Number of Winning Trades / Total Closed Trades) × 100
Why it matters: Win rate alone doesn't tell the full story—a 60% win rate can be unprofitable if losses are much larger than wins. However, it's a key component when combined with risk/reward ratios.
Example: If you have 100 trades with 55 wins and 45 losses, your win rate is 55%. A win rate above 50% is generally considered good, but profitability depends on your risk/reward ratio.
R-Multiple
Definition: The ratio of profit (or loss) to the initial risk taken on a trade. "R" stands for "risk unit"—typically your stop loss distance.
Calculation: Net P&L / Initial Risk (stop loss distance)
Why it matters: R-multiple standardizes trade performance regardless of position size. A 2R trade means you made 2x your risk. This allows you to compare trades of different sizes and understand your true risk/reward profile.
Example: If you risk $100 (stop loss distance) and make $200 profit, that's a 2R trade. If you risk $100 and lose $50, that's a -0.5R trade. Professional traders often aim for average R-multiples above 1.0.
Expectancy
Definition: The average expected value per trade. This tells you how much you can expect to make (or lose) on average for each trade you take.
Calculation: (Win Rate × Average Win) - (Loss Rate × Average Loss)
Why it matters: Expectancy is one of the most important metrics. A positive expectancy means your strategy is profitable over time, even if individual trades lose. A negative expectancy means you'll lose money over time, regardless of short-term wins.
Example: If you win 60% of trades with an average win of $200 and lose 40% with an average loss of $100, your expectancy is (0.6 × $200) - (0.4 × $100) = $80 per trade. This is a positive expectancy system.
Profit Factor
Definition: The ratio of gross profit to gross loss. A simple measure of profitability.
Calculation: Total Gross Profit / Total Gross Loss
Why it matters: Profit factor above 1.0 means you're profitable. Above 2.0 is considered excellent. Below 1.0 means losses exceed profits. It's a quick way to assess overall profitability.
Example: If your total gross profit is $10,000 and total gross loss is $5,000, your profit factor is 2.0. This means you make $2 for every $1 you lose.
Maximum Drawdown
Definition: The largest peak-to-trough decline in your equity curve. It measures the worst losing streak from a high point.
Calculation: The maximum percentage decline from any equity peak to the subsequent trough.
Why it matters: Drawdown tells you how much capital you need to withstand losing streaks. A 30% drawdown means you need to be comfortable losing 30% of your account before recovering. Understanding your maximum drawdown helps with position sizing and risk management.
Important: Drawdowns are inevitable in trading. The key is keeping them manageable and having a plan to recover. Most professional traders aim to keep maximum drawdowns below 20-30%.
Breakdown Analysis
Beyond overall metrics, Trader Diary breaks down your performance by multiple dimensions to reveal patterns:
By Setup
See which trading setups are actually profitable for you. Identify your best-performing strategies and eliminate weak ones.
By Time of Day
Discover your peak trading hours. Some traders perform best in the morning, others in afternoon sessions.
By Instrument/Ticker
Understand which markets you trade best. You might excel in forex but struggle with stocks.
By Direction
Compare long vs. short performance. Some traders are better at one direction than the other.
By Market Condition
Analyze performance in trending vs. ranging markets, high vs. low volatility periods.
By Emotion
Correlate emotional states with outcomes. Do you lose more when trading out of fear or greed?
Equity Curve
The equity curve visualizes your cumulative P&L over time. It shows:
- Overall Trend: Is your account value generally increasing or decreasing?
- Drawdown Periods: When and how deep were your losing streaks?
- Recovery Patterns: How quickly do you recover from drawdowns?
- Consistency: A smooth upward curve indicates consistent performance; choppy patterns suggest inconsistency.
Pro Tip: A healthy equity curve shows steady growth with manageable drawdowns. Sharp drops or extended flat periods often indicate emotional trading or strategy issues that need attention.
Interpreting Your Results
Sample Size Matters
Metrics become meaningful with sufficient data. Aim for at least 30-50 trades before drawing strong conclusions. Early metrics can be skewed by a few good or bad trades.
Look for Patterns, Not Perfection
No trader wins every trade. Focus on patterns: Are you improving over time? Which setups work? What mistakes repeat? The goal is progress, not perfection.
Combine Metrics
Don't rely on a single metric. A high win rate with poor risk/reward can be unprofitable. A low win rate with excellent risk/reward can be very profitable. Look at the full picture.
