Position Sizing for Gold Trading: Risk Before Lot Size

Position sizing converts a trading idea into a defined financial risk. The correct sequence is risk amount, invalidation distance and then lot size.

Published 2026-10-03

Start with the maximum loss you will accept

Before entering a trade, define the maximum account loss that the setup is allowed to create if the stop is reached. This keeps risk consistent across setups with different stop distances.

The appropriate risk level depends on the trader, account structure and strategy; there is no universal percentage that guarantees safety or profitability.

Account for stop distance and contract value

Once the stop distance is known, the position size can be adjusted so that the planned loss remains within the risk budget.

For gold, contract specifications can vary by broker, so traders should verify the exact contract size, tick value and margin requirements on their own trading platform.

Why fixed lot sizes can be misleading

Using the same lot size on every trade can create inconsistent risk because a 100-point stop and a 400-point stop expose the account differently.

Risk-based sizing makes the monetary impact of each trade easier to compare and review.
