Margin Trading, Maintenance Requirements, and Liquidation Risk
Summary
This explainer introduces margin trading as borrowing funds to take a larger market position than the trader’s own capital would permit. Leverage can magnify potential gains, but it also increases losses, and borrowed amounts and applicable fees remain obligations regardless of the trade outcome.
The article describes maintenance margin as a threshold: when account funds fall below the exchange’s requirement, the position may be liquidated or the trader may be asked to add funds. Adding collateral can improve the account’s margin position, while putting that additional capital at risk as well. The explanation notes that exchanges may use insurance funds or socialize losses if a trader cannot meet a call. It is a conceptual overview rather than a detailed calculation guide; it does not specify platform rules or compare liquidation mechanisms across venues.
Key ideas
- Leverage uses borrowed capital to increase position size and magnifies both gains and losses.
- Borrowed funds and fees remain payable even when a trade loses money.
- Falling below the maintenance margin requirement can trigger a margin call or liquidation.
- Adding collateral may improve the margin position, but exposes more funds to loss.
- Exchange insurance funds and loss-sharing mechanisms may address shortfalls as a last resort.
