Intro
Maintenance margin on Aptos futures is the minimum collateral a trader must keep after the initial deposit to keep a position open. When equity falls to this level, the protocol triggers a margin call, forcing the trader to add funds or reduce exposure. Understanding this floor helps participants manage leverage and avoid forced liquidation.
Key Takeaways
- Maintenance margin is a fixed percentage of the initial margin, typically 25‑30% on crypto futures.
- A margin call fires when account equity reaches the maintenance level.
- Traders can satisfy a call by depositing more collateral or closing part of the position.
- Requirements change with market volatility and platform governance.
What Is Maintenance Margin?
Maintenance margin is the lowest equity a trader must retain in a futures account to keep a position alive. According to Investopedia, it is “the minimum amount of equity that must be held in a margin account to continue holding a position” (Investopedia, 2023). On Aptos futures, smart contracts calculate this threshold on‑chain, automatically enforcing the rule.
Why Maintenance Margin Matters
It safeguards the decentralized clearing system by ensuring participants can meet obligations. The Commodity Futures Trading Commission (CFTC) notes that margin requirements lower systemic risk in derivatives markets (CFTC, 2022). For Aptos futures, the maintenance floor prevents cascading liquidations that could destabilize liquidity pools.
How Maintenance Margin Works
The protocol uses the formula:
Maintenance Margin = Initial Margin × Maintenance Margin Ratio
Steps:
- Trader deposits initial margin to open a futures contract.
- System records initial margin and computes the maintenance level (e.g., 25% of initial margin).
- After each price change, the contract updates account equity.
- If equity ≤ maintenance level, a margin call is
