Key Takeaways
- • Fair price calculation uses a median formula incorporating three components: funding rate premium, mid-price basis fair price, and last transaction price—designed to prevent unnecessary liquidations during market volatility on MEXC futures contracts.
- • Funding rate premium adjusts index price by the latest funding rate prorated to hours remaining until the next settlement, ensuring that carrying costs are embedded in the fair price calculation in real time.
- • Mid-price basis fair price smooths spreads by adding a moving average of the bid-ask midpoint deviation to the index price, anchoring fair price to broader market trends rather than single-exchange fluctuations.
- • Fair price determines unrealized PNL and liquidation triggers, protecting traders from forced closures triggered by temporary price spikes unrelated to fundamental market conditions.
- • MEXC applies median aggregation to all three price components, ensuring that no single pricing methodology—whether exchange-specific last price, funding costs, or basis—dominates the calculation during periods of elevated volatility.
Summary
MEXC Futures has published technical specifications for its fair price calculation methodology, which serves as the primary input for unrealized profit-and-loss assessment and liquidation protection across its derivatives platform. The fair price formula employs a median function across three distinct pricing inputs: the funding rate premium (index price adjusted for carry costs), the mid-price basis fair price (index price plus a moving average of the bid-ask spread deviation), and the last traded price updated in real time.
The funding rate premium component incorporates MEXC's perpetual futures funding mechanism by multiplying the index price by one plus the latest funding rate scaled by the time remaining until the next settlement period. This approach embeds carry costs directly into the fair price, preventing situations where traders face mark-to-market losses purely from funding accrual rather than directional price movement. The mid-price basis fair price adds a moving average of the deviation between the midpoint of best bid and ask prices and the underlying index price, effectively filtering out localized exchange-specific spreads and anchoring the calculation to the broader market.
By applying a median function across all three inputs, MEXC's methodology mitigates the risk that temporary price dislocations on any single exchange—whether from order book imbalances, liquidity constraints, or flash volatility—trigger unnecessary liquidations. According to the platform's documentation, this design ensures fair price follows broader market trends rather than short-term fluctuations, thereby protecting user positions during periods of elevated volatility while maintaining alignment with actual market conditions through multiple independent pricing signals.
