Calculation Methods
Fixed Dollar Risk
Risk a fixed dollar amount per trade
Formula: Position Size = Risk Amount / (Entry Price - Stop Loss)
Example: Risk $100, Entry $50,000, Stop $48,000 → Position = $100 / $2,000 = 0.05 BTC
Percentage Risk
Risk a percentage of your account balance
Formula: Position Size = (Account Balance × Risk %) / (Entry Price - Stop Loss)
Example: Account $10,000, Risk 2%, Entry $50,000, Stop $48,000 → Position = $200 / $2,000 = 0.1 BTC
Volatility-Based
Adjust position size based on asset volatility
Formula: Position Size = (Risk Amount × ATR) / (Entry Price - Stop Loss)
Example: Uses Average True Range to adjust for market volatility
Kelly Criterion
Optimal position sizing based on win rate and payoff ratio
Formula: f = (bp - q) / b
Example: Where b = payoff ratio, p = win probability, q = loss probability

Common Mistakes to Avoid
Oversizing Positions
Risking too much per trade can quickly deplete your account.

Changing risk levels frequently makes it hard to track performance.
Not Considering Correlation
Multiple correlated positions can increase your actual risk exposure.
