分析交易策略产生反向交易信号的原因

下面的交易策略交易逻辑：以macd前一日的日线定方向，以15分钟为周期日线是多头方向等15分钟macd死叉后绿柱开始缩短进场买入做多，第2次死叉后绿柱开始缩短加仓，最多持有3手。同理做空，采取跟踪止盈、严格止损、持仓的方向与日线方向不一致时全部平仓。从实测结果看存在日内15分钟开仓与日线相反的情况。因为日内只存在要么做多要么做空。//------------------------------------------------------------------------// 简称: macdDual// 名称: MACD双周期交易系统（日线方向+15分钟柱变化开仓+第2次死叉加仓）// 类别: 策略应用// 类型: 用户应用// 输出: Void//------------------------------------------------------------------------Params Numeric FastLength(12);
