FAQ
How do I calculate position size for crypto?
Position size = (Portfolio × Risk%) ÷ (Entry − Stop). Example: $10K portfolio, 1% risk, entry $100, stop $95. Max loss = $100. Risk per unit = $5. Position = 20 units ($2,000 deployed).
What percentage of my portfolio should I risk per trade?
Professional traders risk 0.5–2% per trade. At 1% risk, 50 consecutive losing trades still leaves 60% of your portfolio. At 5% risk, 14 losses wipes 50% of capital.
What is a good risk-reward ratio?
Minimum 1:2 means you risk $1 to gain $2. At 50% win rate, a 1:2 R/R is profitable. Most professional setups target 1:2.5 or better before taking a trade.
Position sizing is a risk management tool, not a guarantee of profit. Always use stops. NOT financial advice.
