永续合约资金费率是如何计算的？

BitMEX 100倍杠杆永续合约，注册BitMex请使用日本IP：比特币量化交易交流群：191896494

JEX 全球领先的期权交易所

目前永续合约最大的交易所当然是非BitMex莫属了，永续合约最大的特点就是不会交割，多空之间通过资金费率的机制保证合约价格盯住现货价格，那么这个资金费率是如何计算的呢？笔者查看了bitmex官方文档，找到了这个计算公式：

资金费率 (F) = 溢价指数 (P) + clamp (利率 (I) - 溢价指数 (P), 0.05%, -0.05%)

溢价指数 (P) = ( Max ( 0 , 深度加权买价 - 标记价格) - Max ( 0 , 标记价格 - 深度加权卖价)) / 现货价格 + 标记价格的合理基差

这里clamp (利率 (I) - 溢价指数 (P), 0.05%, -0.05%)表示利率 (I) - 溢价指数 (P)这个值在0.05%, -0.05%之间限制，因此资金费用就有了最高限制，对于BTC来说，资金费率最大值为0.375%

那么对于交易量第二的OKEX是如何计算这个资金费率的呢？

okex的计算公式是这样的：

资金费率=Clamp(MA(((合约买一价+合约卖一价)/2-现货指数价格)/现货指数价格 - Interest), -0.25%, 0.25%)

其中Interest为利率，可以看出okex的资金费率也是上下限制，最高为0.25%
