How to Calculate Position Size in Crypto Trading

How to Calculate Position Size in Crypto Trading

Introduction

Position sizing keeps losses consistent and prevents one bad trade from wrecking your account. This guide walks through risk-based sizing, gives examples, and shows how to automate the math with the Position Size Calculator.

Why Position Size Matters

Without sizing, traders swing from tiny to oversized positions based on emotion. Fixed-percentage risk keeps drawdowns shallow and confidence steady.

Step-by-Step Walkthrough

1. Choose risk % (e.g., 1%) of account.

2. Identify entry and stop; measure stop distance.

3. Risk amount = account × risk %.

4. Position size = risk amount ÷ stop distance.

5. Convert to quantity using entry price.

6. Confirm R:R with the Risk Reward Calculator.

Example Scenario

Account $10,000, risk 1% ($100). Entry $2,000 on ETH, stop $1,900 (distance $100). Position size = $100 ÷ $100 = $1,000 notional, or 0.5 ETH. If target is $2,300, reward is $300 on $100 risk = 3:1 R:R.

Trading Tips

- Cut risk to 0.5% during high volatility or after losses.

- If stop distance is wide, reduce size instead of widening risk.

- Avoid stacking correlated trades that collectively exceed your daily risk limit.

- Recalculate when account size changes meaningfully.

FAQ

How much should I risk per trade? Many use 0.5–2%; start low and adjust with experience.
