【宽客策略源码】网格交易(期货)

geek168 数据策略 2019-8-11 15:52 190512人围观

本策略首先计算了过去300个价格数据的均值和标准差，并根据均值加减1和2个标准差得到网格的区间分界线,，并分别配以0.3和0.5的仓位权重
然后根据价格所在的区间来配置仓位(+/-40为上下界,无实际意义):
(-40,-3],(-3,-2],(-2,2],(2,3],(3,40](具体价格等于均值+数字倍标准差)
[-0.5, -0.3, 0.0, 0.3, 0.5](资金比例,此处负号表示开空仓)

回测数据为:SHFE.rb1801的1min数据
回测时间为:2017-07-01 08:00:00到2017-10-01 16:00:00
