<p id="isPasted">Risk-based lot sizing (often called position sizing) is a method where you calculate the volume of a trade based on the specific amount of money you are willing to lose, rather than using a fixed number of lots for every trade. </p><p><strong>Core Principle</strong></p><p>The goal is to ensure that if your Stop Loss is hit, the monetary loss is exactly the same (e.g., 1% of your account), regardless of whether your stop loss is 10 pips or 100 pips away. </p><ul><li>Fixed Risk: You decide to risk a specific percentage (typically 1–2%) or a fixed dollar amount of your total account balance per trade.</li><li>Variable Lot Size: Your lot size increases if your stop loss is tight and decreases if your stop loss is wide. </li></ul><p><strong>The Calculation Formula</strong></p><p>To find your risk-based lot size, use this standard formula: </p><ul><li style="font-style: italic;"><em>Lot Size = (Total Account Risk) / (Stop Loss in Pips × Pip Value per Standard Lot)</em></li></ul><p><br></p><p id="isPasted"><strong>Example:</strong></p><ul><li>Account Balance: $10,000</li><li>Risk per Trade: 1% ($100)</li><li>Stop Loss Distance: 50 pips</li><li>Pip Value (Standard Lot): $10 (for most USD pairs)</li><li>Calculation: $100 / (50 × $10) = 0.20 Lots</li></ul><p><strong>Why Use Risk-Based Sizing?</strong></p><ul><li>Preserves Capital: It prevents a single "bad" trade with a wide stop loss from wiping out a significant portion of your account.</li><li>Consistent Performance: Your losses remain predictable, which helps maintain emotional discipline during losing streaks.</li><li>Account Scalability: As your account balance grows, your 1% risk automatically translates into larger lot sizes, allowing for compounding.</li><li>Adjusts for Volatility: It forces you to trade smaller positions on highly volatile pairs that require wider stop losses. </li></ul><p><strong>Standard Lot Types for Reference</strong></p><p> Lot Type Units of Base Currency Volume (MT4/MT5) Pip Value (approx.
