Leverage and Margin in Trading: A Risk Guide
By Daniel Chau
Founder, NeuroBacktest
Understand how leverage amplifies gains and losses, and how to backtest margin strategies safely.
Leverage is a double-edged sword. It can accelerate profits, but it also accelerates drawdowns and increases the risk of ruin.
How Leverage Works
A 2x leveraged position doubles both gains and losses. A 50% drawdown on a 2x leveraged account is a full loss of capital.
Margin Calls
If your account equity falls below the broker's maintenance margin, you will face a margin call and forced liquidation, often at the worst possible time.
Backtesting Leverage
Apply a leverage multiplier to your backtest returns and run Monte Carlo simulations. If the worst-case scenario wipes out the account, reduce leverage or tighten risk rules.
