Position Sizing and Risk Management: How Much to Risk per Trade (With Formula and Examples)

Short answer: risk a fixed 1–2% of your account on each trade. Calculate the lot size with this formula: lot size = (account × risk %) ÷ (stop loss in pips × pip value per lot). The stop loss comes from the chart; the lot size adjusts so the money at risk stays the same.

Why position sizing matters more than entries

Even a good strategy has losing streaks. If you risk 10% per trade, five losses in a row cost about 40% of the account. At 1% per trade, the same streak costs about 5%. Position sizing decides whether you survive long enough for your edge to work.

The position size formula

Lot size = (Account balance × Risk %) ÷ (Stop loss in pips × Pip value per standard lot)

• Account balance: the money in your account.
• Risk %: the share of the account you accept to lose if the stop is hit (1–2%).
• Stop loss in pips: the distance from entry to stop, based on the chart, not on money.
• Pip value: for pairs quoted in USD (EURUSD, GBPUSD), one pip on one standard lot is $10.

Example 1: EURUSD

• Account: $5,000, risk 1% = $50
• Entry 1.1130, stop 1.1155 = 25 pips
• Lot size = 50 ÷ (25 × 10) = 0.20 lots

If the stop is hit, you lose $50, exactly 1% of the account.

Example 2: Gold (XAUUSD)

On most brokers, one lot of gold is 100 ounces, so a $1 move is worth $100 per lot.

• Account: $5,000, risk 1% = $50
• Stop distance: $8
• Lot size = 50 ÷ (8 × 100) = 0.06 lots (rounded down)

The risk rules we recommend

Rule	Why it matters
Risk 1–2% per trade	Survives long losing streaks
Minimum reward-to-risk of 1:2	You can be profitable even with a win rate below 50%
Daily loss limit of 3–5%	Stops revenge trading on bad days
Never widen a stop	A stop is a decision made with a clear head
Reduce size after a drawdown	Protects capital while confidence returns

Losses are harder to recover than they look

Loss	Gain needed to break even
10%	11.1%
20%	25%
30%	42.9%
50%	100%

This is why protecting capital comes first.

Frequently asked questions

Is 1% risk per trade too small?

For most traders it is the right starting point. Professionals often risk 0.5–1% because consistency matters more than any single trade.

Should I set my stop by money or by the chart?

By the chart. Put the stop where the trade idea is proven wrong, then adjust the lot size to fit your risk.

What if the calculated lot size is too small for my broker?

Use a broker that offers micro lots (0.01), or skip the trade if the stop is too wide for your account.

Does leverage change my risk?

Leverage only sets how much margin you need. Your real risk is set by lot size and stop distance.
