A lot is a standardized unit of a trading position. In gold (XAU/USD), 1 standard lot = 100 oz. For Bitcoin, lot size represents the quantity of BTC you're buying or selling. Using the right lot size is essential for consistent risk management.
Professional traders typically risk 1–2% of capital per trade. Beginners should start at 0.5–1%. Risking more than 5% per trade dramatically increases the chance of account blow-up, especially during a losing streak.
The formula is: Lot Size = (Capital × Risk%) ÷ (Stop Loss in pips × Pip Value). For XAU/USD, our calculator applies the gold pip value automatically. For BTC/USD, it calculates based on the price difference.
For gold (XAU/USD), 1 pip = $0.01 price movement. The pip value for 1 standard lot of gold is approximately $1. Our calculator handles this automatically so you only need to enter your entry and stop-loss prices.
Over-leveraging means using a lot size too large for your account. Even a small adverse move can cause losses larger than your account can absorb, leading to a margin call or full account wipe. Proper lot sizing is the single most important skill in risk management.
