You can start with as little as $100 USD or equivalent, making it accessible for traders with limited capital, especially when using cent accounts or micro accounts that allow smaller position sizes. Cent accounts effectively multiply your capital 100x (so $100 operates like $10,000 in a cent account), providing adequate margin for the trading logic. However, for optimal performance, better trade scaling, reduced stress from equity fluctuations, and comfortable cushion during drawdown periods, the vendor recommends starting with $300-$500 or more. Larger account balances provide more flexibility for position sizing, allow the EA to operate with its intended risk parameters, and reduce the likelihood of premature account depletion during normal losing streaks.
