What is the smallest position size I can trade with a forex broker?

The smallest position size at most forex brokers is 0.01 lots, known as a micro lot, representing 1,000 units of the base currency. For EUR/USD, this means risking about 0.10 USD per pip movement. Cent or nano accounts scale this further to effectively 0.01 micro lots in cent terms. Minimums suit beginners testing strategies with tiny risk. Some brokers set higher minimums on certain exotics or during promotions. Always check the contract specifications for each instrument. Small sizes help with precise risk management but may widen effective spreads as a percentage of position value. Use them to scale into larger trades as confidence grows.
