Guide to Multi-Asset Position Sizing
What Is Position Sizing?
Position sizing determines how large a trade should be, given a specific level of acceptable risk. Rather than guessing how many shares to buy or what lot size to use, a position sizing formula calculates the exact quantity so that if your stop-loss is hit, you lose only a predefined percentage of your account — protecting your capital over many trades.
Position Sizing Formulas by Asset Class
Forex
Lot Size = Risk Amount ÷ (Stop Pips × Pip Value per Lot)
1 pip = 0.0001 for most pairs; pip value ≈ $10 per std lot for USD pairs
Stocks
Shares = Risk Amount ÷ (Entry Price − Stop Loss Price)
Risk is capped at the monetary stop distance per share
Crypto
Coins = Risk Amount ÷ (Entry Price − Stop Loss Price)
Same as stocks; result is fractional coins for high-price assets like BTC
Commodities / Indices
Contracts = Risk Amount ÷ (Price Distance × Contract Size)
Gold: 100 oz/contract; Crude Oil: 1,000 bbl/contract; S&P 500: 50×/contract
Managing Total Portfolio Risk
| Total Portfolio Risk | Assessment | Recommendation |
|---|---|---|
| ≤ 2% | ✅ Conservative | Safe for most traders; comfortable drawdown levels |
| 2% – 5% | ⚠️ Moderate | Acceptable if trades are uncorrelated; watch carefully |
| 5% – 10% | 🚨 Aggressive | Significant drawdown risk; reduce position sizes |
| > 10% | 🚨 Very Aggressive | Account can decline rapidly; cut positions immediately |
Asset Correlation and Compounded Risk
Trading multiple assets that move together dramatically multiplies your actual risk. For example, EUR/USD and GBP/USD are highly correlated; if USD strengthens both trades will lose simultaneously, and your effective risk doubles even if each trade individually is set to 1%.
Diversify across uncorrelated assets (e.g., Forex + Gold + a stock) to spread risk. Use the portfolio summary view to monitor your total exposure in real time.
High Correlation (Avoid)
- EUR/USD + GBP/USD
- EUR/USD + AUD/USD
- BTC/USD + ETH/USD
- Gold + Silver
Lower Correlation (Better)
- EUR/USD + USD/JPY
- Forex + Crypto
- Stocks + Gold (XAU)
- Indices + Commodities
