Is the Maintenance Margin Percentage the Same for a Perpetual Swap and a Quarterly Futures Contract?

Not necessarily. While they may be similar, the maintenance margin percentage can differ based on the contract type and the underlying asset's risk profile.

Quarterly futures have a fixed expiry date, which can sometimes influence the margin calculation. Perpetual swaps, with their funding rate mechanism and no expiry, are generally the primary focus of the exchange's risk system, but the margin rules are set by the exchange and may vary.
