策略说明

交易标的:比特币(BTC)

价差数据:BTC 永续 - BTC 季度(省略协整性检验)

交易周期:1 分钟

头寸匹配:1:1

交易类型:同品种跨期

做多价差开仓条件:如果当前账户没有持仓,并且价差 < (长期价差水平 - 阈值),就做多价差。即:买开 BTC 永续,卖开 BTC 季度。

做空价差开仓条件:如果当前账户没有持仓,并且价差 > (长期价差水平 + 阈值),就做空价差。即:卖开 BTC 永续,买开 BTC 季度。

做多价差平仓条件:如果当前账户持有 BTC 永续多单,并且持有 BTC 季度空单,并且价差 > 长期价差水平,就平多价差。即:卖平 BTC 永续,买平 BTC 季度。

做空价差平仓条件:如果当前账户持有 BTC 永续空单,并且持有 BTC 季度多单,并且价差 < 长期价差水平,就平空价差。即:买平 BTC 永续,卖平 BTC 季度。

举个例子,假设 BTC 永续 和 BTC 当季的价差长期维持在 35 左右。如果某一天价差达到 50 ,我们预计价差会在未来某段时间回归到 35 及以下。那么就可以卖出 BTC 永续,同时买入 BTC 当季,来做空这个价差。反之亦然,注意 BTC 永续 和 BTC 当季 的价差总会回归到0附近(到期交割),所以价差为正的时候,优先做空价差,价差为负的时候,优先做多价差。
