1）标记价格
为了提高合约市场稳定性，减少市场异常波动时不必要的强制平仓，我们使用标记价格来计算用户的未实现盈亏。
基差移动平均值=移动平均值（合约中间价 – 现货指数价格）=移动平均值（（合约卖一价 + 合约买一价）／2 – 现货指数价格）
标记价格同时考虑了现货指数价格及基差的移动平均值。移动平均值机制平滑过滤短时间内的合约价格波动，减少异常波动产生的不必要强制平仓。
2）指数价格
币本位保证金合约采用相应标的的USD指数。为保证现货指数价格合理反应每个币种公允的现货市场价格，我们会针对每个合约币种选择3家以上主流交易所的币对作为指数权重成分，并设计了异常处理逻辑，保证单个交易所价格出现大幅偏离时，指数波动在正常范围内。
现货指数价格计算逻辑：
a.实时获取该币种所有指数成分交易所币对最新成交价及成交量
b.系统维护或最新成交价及成交量一段时间内未更新的交易所置为无效，本次不参与计算
c.计价货币为BTC的币对，乘以欧易 BTC美元指数，换算为美元价格
d.判断当前剩余有效交易所数据有几家：
=3家，按相等权重加权有效交易所数据（如果某家交易所价格相对所有交易所价格中位数偏差3%以上，则该交易所价格按照中位数0.97或中位数1.03计算）
=2家，按相等权重加权有效交易所数据
=1家，直接取剩余一家有效交易所的价格作为指数价格
3）委托价格
在限价委托等交易委托策略中，交易者下单时需要指定交易委托的买卖价格，只有当市场价格满足委托价格时订单才会执行，该价格即为委托价格。
