It is a trader’s statistics that allow us to separate emotional perceptions of results from the actual picture. Without a systematic analysis of a trader’s trades, any conclusions about whether a strategy "works" or "doesn’t work" will be subjective. A trader’s journal is crucial for recording and organising this data: it transforms chaotic trades into clear trading statistics that can be analysed, compared and improved. Objective evaluation of a trading system is impossible without quantitative metrics. They help separate emotional perception from the actual performance. ### 1) Win Rate (Percentage of Profitable Trades) Formula: **Win Rate = (Number of Winning Trades ÷ Total Number of Trades) × 100%** **Interpretation:** - Below 40% - the strategy requires serious revision - 40–50% - acceptable if the profit/risk ratio is strong - 50–60% - good for most strategies - Above 60% - excellent result (but check the profit/loss ratio). **Important note**: a high win rate does not guarantee profitability. A strategy with a 70 per cent win rate but a profit-to-loss ratio of 1:3 will be unprofitable. At the same time, a strategy with a win rate of just 40 per cent and a ratio of 3:1 in favour of profit will consistently generate income. In a trader’s journal, it is useful to record the win rate for individual types of signals (for example, breakouts, rebounds from levels) – this helps to understand which parts of the strategy are working and which are dragging the results down. ### 2) Average Profit and Average Loss Formulas: **Average Profit = Total Profit ÷ Number of Winning Trades\ Average Loss = Total Loss ÷ Number of Losing Trades** **Why it matters:** These indicators reveal an imbalance in trade management. If the average loss is significantly higher than the average profit, this is a sign of a problem – you are either taking profits too early or holding losing positions for too long. **Ideal ratio:** Average profit should be at least 1.5x greater than average loss. When analysing a trader’s trades, it is useful to look at trades across different timeframes or instruments separately: sometimes the overall statistics look fine, but there may be problematic segments hidden within them. For example, on one asset, the average profit may be twice as high as the loss, whilst on another, the opposite may be true. ### 3) Profit Factor Formula: **Profit Factor = Total Profit from Winning Trades ÷ Total Loss from Losing Trades** **Interpretation:** - Below 1.0 - losing system - 1.0–1.5 - profitable but weak - 1.5–2.0 - good system - Above 2.0 - excellent system - Above 3.0 - check for insufficient data or overfitting. **Example:** - Total Profit: 5,000 USDT - Total Loss: 2,500 USDT - Profit Factor = 5,000 ÷ 2,500 = 2.0 This means that for every dollar of loss, you make a profit of two dollars. When calculating the profit factor, it is useful to use trading statistics from a trader’s journal, where each trade is already classified as either profitable or loss-making. This reduces the risk of errors in the calculations. ### 4) Expected Value (Average Result per Trade) Formula: **Expected Value = (Win Rate × Avg Profit) - ((1 - Win Rate) × Avg Loss)** **Interpretation:** - Negative - unprofitable system - 0–0.5% of deposit - weak profitability - 0.5–1% - good system - Above 1% - excellent system. **Example:** - Win Rate: 55% (0.55) - Average Profit: 50 USDT - Average Loss: 40 USDT EV = (0.55 × 50) - (0.45 × 40) = 27.5 - 18 = **9.5 USDT per trade.** With a 10,000 USDT deposit, that’s 0.095% per trade. 20 trades per week → **Expected weekly return: 1.9%** Regularly calculating the expected return based on a trader’s statistics helps to spot any deterioration in signal quality in good time and adjust the strategy before losses become critical. ### 5) Maximum Drawdown (Max DD) This is the largest drop in capital from a local high to the next low. Formula: **Drawdown = ((Max Balance - Min Balance after Max) ÷ Max Balance) × 100%** **Example:** - Max balance: 12,000 USDT - Dropped to: 10,200 USDT - Drawdown = ((12,000 - 10,200) ÷ 12,000) × 100% = **15%** **Interpretation:** - Up to 10% - normal - 10–20% - elevated, needs attention - 20–30% - critical, needs strategy revision - Above 30% - dangerous zone, high risk of account blowout. **Using this metric**: compare the current drawdown with the historical maximum. If the current drawdown is approaching or exceeds the maximum, this is a signal to reduce risk or pause trading. In your trading journal, it is worth making a separate note of instances of significant drawdowns: which trades caused them, the circumstances under which they occurred, and how you reacted. Analysing your trades in this way will help you avoid repeating the same mistakes in the future. ### 6) Recovery Factor Formula: **Recovery Factor = Net Profit ÷ Max Drawdown** **Interpretation:** - Below 2 - slow recovery - 2–5 - acceptable recovery - Above 5 - strong recovery. **Example:** - Net profit: 3,000 USDT - Max drawdown: 1,000 USDT - Recovery Factor = 3,000 ÷ 1,000 = **3** This means that the profit is three times greater than the maximum drawdown – a good indicator of the system’s stability. A high Recovery Factor indicates that, even after significant drawdowns, the system is capable of quickly regaining lost ground. This is particularly important when employing an aggressive approach to capital management. ### 7) Sharpe Ratio (Simplified for Trading) Shows how much return you get per unit of risk. Simplified formula: **Sharpe = Average Return over Period ÷ Standard Deviation of Returns** Where: - **Average Return** is the mean result of all trades (in % or currency) - **Standard Deviation** reflects how much results fluctuate from the average→ the higher the deviation, the less predictable your results. **Steps to calculate standard deviation:** 1. Find the average return. 2. Subtract average from each trade's return. 3. Square the differences. 4. Sum the squares and divide by number of trades. 5. Take the square root of the result. Formula: **√\[Σ(Trade Return - Average Return)² ÷ Number of Trades\]** **Example:** - Trades: +5%, +3%, -2%, +4% - Average: 2.5% - Deviations: (5-2.5)² = 6.25, (3-2.5)² = 0.25, (-2-2.5)² = 20.25, (4-2.5)² = 2.25, Sum = 29 - Std. Dev = √(29 ÷ 4) **≈ 2.69%** **Interpretation:** - Below 1 - poor risk-adjusted returns - 1–2 - acceptable - 2–3 - good - Above 3 - excellent. For most novice traders, this indicator is far too complex. Focus on simpler metrics: the profit factor, win rate and maximum drawdown. However, as you gain experience, analysing your trades using the Sharpe ratio allows you to assess the stability of your profits and the quality of your risk management in greater depth. ### How to Keep a Trader’s Journal and Compile Statistics For trading statistics to be useful, it is important to record not only the result but also the context of each trade: - Date and time of entry/exit. - Instrument and timeframe. - Type of signal (breakout, retracement, divergence, etc.). - Entry price, stop-loss and take-profit levels. - Actual result in monetary terms and as a percentage. - A brief description of the reason for entry and exit. - Emotional state (optional, but useful for long-term analysis). This approach transforms a trader’s journal from a simple record of trades into a fully-fledged analytical tool. It can be used to generate reports, segment trades and identify patterns that are not apparent at first glance. ### Practical Tips for Analysing Statistics - **Consistency**: analyse a trader’s statistics at least once a week. This allows you to spot any deterioration in performance promptly. - **Segmentation**: categorise trades by type, timeframe and instrument. This will help you understand exactly where problems are arising. - **Trends**: look not only at current figures, but also at how they change over time. For example, a decline in the profit factor over several weeks is a warning sign. - **Objectives**: Compare your performance metrics against your trading objectives. If the expected return is too low for your desired level of profitability, you need to change your strategy or increase the number of trades (if permissible). ### Common Mistakes When Working With Statistics - Keeping a trading journal but not analysing it. A journal in itself does not improve results — it only becomes useful when the trader’s trades are analysed regularly. - Ignoring the context of trades. Simply adding up profits and losses can obscure important details. - Evaluating a system based on too small a sample size. A minimum of 50–100 trades is required for reliable conclusions. - Changing the rules of a strategy whilst collecting statistics. This distorts the results and renders the trading statistics irrelevant. - Focusing solely on the win rate. As already noted, a high percentage of profitable trades does not guarantee a profit. ### The Role of Statistics in a Trader’s Long-Term Development **A trader’s statistics** are not merely a set of figures, but a record of your decisions and their consequences. Regularly analysing your trades helps you identify the strengths and weaknesses of your strategy, correct mistakes and gradually improve your results. A trader’s journal becomes your personal textbook: it records not only successful trades, but also those that have taught you something important. Over time, your trading statistics will enable you not just to ‘trade’, but to manage your profits and risks in an informed manner, relying on facts rather than intuition.
