BitMEX Model

Algorithm

The BitMEX Model, initially prominent in cryptocurrency derivatives, represents a specific approach to perpetual contract design and market making, emphasizing a funding rate mechanism to anchor contract prices to underlying spot markets. This design incorporates a tiered funding rate, incentivizing traders to maintain positions aligned with the spot index, thereby reducing arbitrage opportunities and promoting price convergence. Its core function relies on continuous calculation and adjustment of these rates based on the difference between perpetual contract and spot prices, influencing trader behavior and market equilibrium. The model’s success stemmed from its ability to facilitate high liquidity and efficient price discovery in a nascent market, though it also introduced complexities related to manipulation and funding rate gaming.
