Leverage on an evaluation account expresses the maximum notional position size a trader may hold relative to the account's nominal balance. It is a ratio: for every unit of stated balance, the platform permits a position of some multiple of that unit. It functions as a ceiling imposed by the account settings, not an instruction or a default trade size. A trader operating far below the ceiling is unaffected by where the ceiling sits; the figure only becomes binding at the point an order would exceed it, at which stage the platform rejects or truncates the order.
The ceiling interacts directly with the account's loss rules, and the interaction runs in the opposite direction to intuition. A higher permitted multiple means a given adverse price move produces a larger currency loss, because the position behind it is larger. Since evaluation accounts terminate when a daily or overall loss threshold is breached, a higher ceiling shortens the distance between an ordinary market fluctuation and a failed evaluation for anyone who uses that ceiling. Leverage widens the range of position sizes available; the loss limit narrows the range of outcomes tolerated. Read alone, a generous leverage figure describes only the first of these.
Within a single account, leverage is usually not uniform. Currency pairs typically carry the highest permitted multiple, with index and commodity products lower, and single equities or crypto instruments lower still. The headline number quoted in marketing normally refers to the most permissive instrument class. A trader whose strategy sits in a different class operates under a different ceiling on the same account, which is set out in the instrument specifications rather than the headline.
The common misreading treats leverage as a measure of how much room the account gives. It is not. The binding constraint on an evaluation account is the loss threshold, and that threshold is denominated in currency against the account balance regardless of how the position was sized. Two accounts with identical leverage but different daily loss rules behave differently; accounts with different leverage but identical loss rules converge in behaviour for any trader sizing positions by risk rather than by maximum permitted volume.
