您修改核心的解决方案ruleOrderProc
Quantstrat 中的函数看起来不错。如果您正在寻找一个开箱即用的解决方案来解决您的问题,并且不需要修改 quantstrat 源代码,您可以使用方便的"trigger"
订单数量参数。正如 Quantstrat 文档中所述ruleSignal
在发现ruleSignal.R
:
\code{orderqty} 应该是数字,或者“all”/“trigger”之一。 'all' 只能与ruletype='exit' 的顺序一起使用
或“风险”,并将关闭整个头寸。 ‘触发’只能是
与ruletype='chain'一起使用,与'all'完全相同,除了
实际交易被抑制,可以用来启动
新的订单链。
这是一个独立的简化策略,我认为它可以满足您的需求。
请注意,如果带有触发器的限价订单被成交,则不会发生实际交易(请查看来源ruleOrderProc
你会看到addTxn
如果它是 a 则不会被调用trigger
数量)。
交易工具为GBPUSD,数据来自Quantstrat。当 MACD 信号从下方穿过 0 时,该策略进入多头头寸。如果 MACD 信号低于 0,则所有未平仓多头头寸都会被平仓。如果在入场时价格上涨超过价格的 0.05%(请记住,这是外汇汇率,因此与股票相比,预期变动百分比较小),则任何未平仓的追踪止损都将转换为止损限价。
这种方法需要定义一个新的规则函数来处理从 stoptrailing 到 stoplimit 的转换。
