本策略的主要思想是通过随机数来决定入场点,设置了三个止盈点和一个止损点来管理风险,以控制每次交易的盈亏。
该策略使用随机数rd_number_entry在11到13之间来决定做多入场点,使用rd_number_exit在20到22之间来决定平仓。做多后设置stop loss为入场价减去atr(14)* slx。同时设置了三个止盈点,第一个止盈点为入场价加上atr(14)* tpx,第二个止盈点为入场价加上2* tpx,第三个止盈点为入场价加上3* tpx。做空的原理类似,区别在于入场决定在rd_number_entry取值不同,止盈止损方向相反。
该策略可以通过调整tpx(止盈系数)和slx(止损系数)来控制风险。
该策略具有以下优势:
该策略也存在以下风险:
可以通过调整止盈止损系数,优化随机入场逻辑来降低风险。
该策略可以从以下几个方面进行优化:
本策略以随机入场为基础,设置多个止盈止损点控制单笔交易风险,由于随机性强可以减少曲拟合概率,通过参数优化可以降低交易风险。后续优化空间还很大,值得进一步研究。
