本策略基于MACD指标设计了一个可以控制每笔交易风险的长线交易策略。相比传统的做多做空翻转策略,本策略更加注重每笔交易的风险控制。策略通过计算目标止损价位和止盈价位,设定合理的仓位大小,限制每笔交易可能造成的最大损失。这可以有效控制回撤,获得长期稳定收益。
本策略首先计算MACD指标的macd线和signal线。当macd线从下向上突破signal线时,判断为买入信号。为过滤假突破,策略要求barssince(crossover(macd_line, signal_line)) <= 5,即突破发生在最近5根K线内。同时要求macd线和signal线均低于0,表明目前处于超卖状态,以及收盘价高于wma均线,表明趋势向上。满足上述条件时,进行买入开仓。
对每笔交易,策略计算合理的止损价位和止盈价位。止损价位设定为最近3根K线的最低价。止盈价位设定为买入价格加上止损价位到买入价格距离的4倍。
关键的是,策略根据可承受的风险计算每笔交易的具体仓位。通过参数capital_risk设定每笔交易最大可承受的损失占总资金的百分比。然后根据止损幅度计算以美元计的仓位大小。再转换为合约数进行买入开仓。
每次交易风险控制在总资金的1%以内,可以有效控制回撤。同时,止盈位置较大,可以获得较高收益。
可以考虑:
本策略基于MACD指标判断趋势方向,以控制风险为先导,计算合理仓位进行交易。关键在于风险控制和仓位优化,可以获得长期稳定收益。但MACD指标存在一定缺陷,止损止盈机制也需进一步优化。如果进一步优化指标运用、止损止盈设定以及降低交易频率,会使策略更加强大。
