Using Leverage to Size Positions Across Exchanges Within a Risk Budget
Summary
The article explains how leverage can increase liquidation risk while also allowing a trader to size a position using only the funds held at one venue. Its examples start with a total portfolio of $20,000, with $5,000 at the exchange, and a chosen maximum loss of $600 per trade. With a 3% stop, a $20,000 position would meet that loss limit and require 4x leverage on the exchange balance. With a 1.5% stop, a $40,000 position would correspond to 8x leverage for the same planned loss.
The underlying method is to calculate position size from the intended dollar risk and stop distance, then use leverage to obtain that exposure without moving the entire portfolio to one exchange. This can reduce the amount of capital concentrated at a venue, but it does not eliminate trading or counterparty risk. The article warns that higher leverage moves liquidation closer and liquidation may consume the position or account. The examples do not account for fees, slippage, changing stop execution, margin rules, or gaps, so planned risk may differ from realized loss.
Key ideas
- Set a maximum dollar loss before determining the position size.
- A wider stop requires a smaller position to keep the same planned loss.
- Leverage can provide exposure using a smaller balance held at one exchange.
- Higher leverage brings the liquidation price closer and can increase account risk.
- The examples omit execution costs and other factors that can alter realized losses.
