Leverage and Margin: A Beginner’s Guide
Understand notional exposure, required margin, liquidation risk and why higher leverage does not make a trade more profitable.
Leverage allows a trader to control a position whose notional value is larger than the capital posted as margin. It does not multiply market skill or improve the probability of a trade. It increases exposure relative to committed capital, so both gains and losses can become large compared with the margin reserved for the position. Understanding the difference between account balance, equity, margin and notional exposure is essential before trading leveraged products.
Margin is collateral, not maximum loss
Initial margin is the amount required to open a leveraged position. Maintenance margin is the minimum equity the platform requires to keep it open. If losses reduce equity too far, the platform may request additional funds, reduce positions or liquidate them according to its rules. The margin shown at entry is not necessarily the most you can lose. Fees, funding, gaps and slippage can affect the final result.
Control exposure, not the leverage selector
A platform may offer a high maximum leverage setting, but position size and stop distance determine planned trade risk. Two traders using the same leverage can have very different exposure. Calculate the notional value, estimate the loss at the stop and keep free margin for volatility. Isolated margin can contain risk to a position, while cross margin may use more account equity; implementation varies by venue. Read contract specifications before trading.
