TOOLS · RISK

Know your size.Before you enter.

Work out the lot size that puts the amount you chose at risk if your stop is hit. It runs in your browser and sends nothing.

Position size

The money in the account, in dollars.

The share of the balance you accept losing if the stop is hit.

Price distance, e.g. 2.50 = $2.50 move in gold. Not pips.

Ounces of gold in one lot. 100 is common; change it if your broker uses another size.

Result

Enter your balance, risk and stop distance to see the lot size.

How it is worked out

  1. $ at risk = balance × risk % ÷ 100
  2. $ per $1 move, for one lot = contract size
  3. Lots = $ at risk ÷ (stop distance × contract size)
  4. The lots are rounded down to 0.01, never up.

Worked example

A $10,000.00 balance, 1% risk, a $5.00 price stop and 100 oz per lot gives 0.20 lots. That is $100.00 at risk and $20.00 for each $1 move.

What this does not know

  • Your broker's spread, commission, swap and margin rules.
  • Slippage: a stop can fill at a worse price than the one you set, so a loss can be larger than the amount shown.
  • Whether the trade is a good one. This only sizes it.
