Every position size calculation comes down to one line:
Lots = Risk $ ÷ (Stop distance × $ per point per lot)
Your risk is a slice of your account, often 1%. Your stop distance comes from the chart, not from how much you want to make. The $ per point depends on the market: 1 lot of gold is 100 ounces, so a $1 move is $100. One lot of NAS100 or US30 is usually $1 per point.
Also useful: the risk-reward calculator shows the win rate you need for your target.
Lot size = money you are willing to risk ÷ (stop distance × value of a 1-point move for 1 lot). For example, risking $200 on gold with a $4 stop: 200 ÷ (4 × $100) = 0.50 lots.
Many day traders risk 0.5% to 1% of their account per trade, and rarely more than 2%. Small, consistent risk keeps a losing streak from wiping out weeks of gains.
Contract sizes vary between brokers and account types. This calculator uses common CFD specs (for example 1 lot of XAUUSD = 100 oz, 1 lot of NAS100 = $1 per point). Check your broker's contract specification and adjust if needed.
Yes for pairs quoted in USD (like EURUSD) and USD-base pairs (like USDJPY), using a standard 100,000-unit lot. For crosses like EURGBP, the P&L currency isn't USD, so convert your risk first.
