Leverage

Leverage is the multiplier between cash deposited (or allocated) and the notional value of positions a trader can hold. In prop trading, leverage is usually built into the account structure rather than borrowed explicitly — the firm extends buying power and the trader operates within drawdown limits.

Leverage limits vary substantially by asset class. Forex prop accounts often extend 30:1 to 100:1 leverage. Futures leverage is determined by exchange initial-margin requirements, which prop firms typically allow trading at reduced day-trading margins. Equity prop firms operate under FINRA rules: 4:1 intraday and 2:1 overnight for accounts above $25k.

Time-of-day matters. Many firms apply tighter overnight leverage than intraday — sometimes halving buying power between session close and open. Holding positions through the transition can trigger a forced reduction or a margin event.

For first-loss / leveraged-trader-capital firms, leverage is the entire structural appeal: deposit $5,000, control $100,000 of trading capital. The amplification cuts both ways — the same multiplier that makes profit larger also accelerates account breach. Effective leverage should always be calculated against drawdown rules, not just account size.
