How Position Sizing Works
Position sizing is the #1 risk management technique used by professional traders. The formula:
Position Size = (Account Balance × Risk %) ÷ Stop Distance
Stop Distance = |Entry Price − Stop-Loss Price|
Example: $10,000 account, 1% risk, BTC entry $85,000, stop $83,000:
- Max loss = $10,000 × 1% = $100
- Stop distance = $85,000 − $83,000 = $2,000 per BTC
- Position size = $100 ÷ $2,000 = 0.05 BTC
Professional traders typically risk 0.5%–2% per trade. The 1% rule is the most widely followed standard.
FAQ
How do you calculate crypto position size?
Position size = (Account balance × Risk %) ÷ Stop distance. Example: $10,000 account × 1% = $100 max loss. If entry is $85,000 and stop is $83,000 (a $2,000 distance), position size = $100 ÷ $2,000 = 0.05 BTC.
What is a good risk percentage per trade in crypto?
Professional traders risk 0.5%–2% of their account per trade. 1% is the most common rule. Risking more than 3% per trade is considered aggressive and can lead to account drawdown after a losing streak.
What is the 1% rule in trading?
The 1% rule means never risking more than 1% of your total account on any single trade. With a $10,000 account your max loss per trade is $100. This rule protects against large drawdowns during losing streaks.
What is a good risk-to-reward ratio?
A minimum of 1:2 (risk $1 to make $2) is generally recommended. Professional traders often target 1:3 or better. A ratio below 1:1 means your wins need to outnumber your losses to be profitable.
How does leverage affect position size?
Leverage amplifies both gains and losses. With 10× leverage, a 1% price move equals a 10% account change. Your stop-loss distance should be set before applying leverage. This calculator shows the margin required at your chosen leverage.
