Crypto Perpetual Swaps: Margin, Liquidation, and Risk Controls

Summary

The document introduces perpetual swaps as crypto derivatives with no expiry that let traders take long or short positions without owning the underlying asset. It explains how leverage magnifies the notional exposure relative to posted margin, distinguishing initial margin needed to open a trade from maintenance margin needed to keep it open. In the described exchange setting, liquidation is triggered when the maintenance margin ratio reaches 100% or less, and the position may be closed at a market price that differs from expectations.

Suggested risk controls include monitoring the margin ratio, setting alerts and stop losses, and using lower leverage or smaller positions to preserve a margin buffer. The examples explain mechanics rather than establish a profitable approach, and they provide no strategy testing or performance evidence. Liquidation can occur rapidly in volatile markets, and the stated leverage limit and account rules are specific to the described venue and pairs. The document warns that traders can lose all collateral and notes that some services are described as unregulated.

Key ideas

• Perpetual swaps allow long or short exposure to crypto prices without contract expiry or asset ownership.
• Leverage allows a position’s notional value to exceed the margin posted as collateral.
• Initial margin opens a position, while maintenance margin supports keeping it open.
• The described venue triggers liquidation when the maintenance margin ratio reaches 100% or less.
• Margin alerts, stop losses, and lower leverage are suggested as risk controls, though they do not remove liquidation risk.
