MEXC Futures has updated its AJGUSDT perpetual contract pricing mechanism, clarifying how the index price and fair price are calculated. For traders navigating volatile markets, understanding these benchmarks is crucial to avoiding unnecessary liquidations and making informed entries. Here’s what the latest update means for your futures strategy.

What Is the Index Price for AJGUSDT?

The index price is the backbone of any perpetual contract—it reflects the global spot market average for AJGUSDT, rather than relying on a single exchange’s order book. MEXC aggregates price data from multiple major spot exchanges to produce a robust, manipulation-resistant index.

This index price serves as the reference for calculating unrealized profit and loss (PnL) and determining liquidation triggers. By using a composite, MEXC reduces the impact of any single exchange’s anomalous price spikes or dips.

Why It Matters for Your Trades

  • Fairer liquidations – Index-based triggers prevent flash-crash wipes on one platform.
  • Better arbitrage – Traders can spot discrepancies between the index and the mark price.
  • Global consistency – The index aligns AJGUSDT pricing across different venues.

Fair Price vs. Mark Price: The Key Difference

While the index price is derived from spot markets, the fair price (often called the mark price) incorporates funding rates and basis. The fair price is calculated as the index price plus a moving average of the funding basis, ensuring that the contract price doesn’t deviate too far from the underlying index.

MEXC uses the fair price for valuing open positions and computing unrealized PnL. This prevents traders from being liquidated due to temporary contract price spikes that don’t reflect the broader market.

How Funding Rates Influence Fair Price

When the perpetual contract trades above the index, funding rates turn positive, encouraging shorts. Conversely, a discount leads to negative funding, favoring longs. The fair price smooths these fluctuations, giving traders a more stable reference for risk management.

Practical Implications for AJGUSDT Traders

For those actively trading AJGUSDT on MEXC Futures, the updated index and fair price mechanisms mean you should monitor both values in the trading interface. The spread between the index and the contract price can signal market sentiment.

When the fair price is significantly higher than the index, it may indicate excessive bullish leverage. Conversely, a deep discount could suggest panic selling. Use these signals to adjust your positions accordingly.
