该策略采用EMA均线 golden cross 生成交易信号,即快速EMA线上穿慢速EMA线时产生买入信号,快速EMA线下穿慢速EMA线时产生卖出信号,属于典型的趋势跟踪策略。同时,策略利用ATR指标设定动态止损位,在保证盈利的同时控制风险。
解决方法: 1. 可适当放宽ATR倍数,确保止损离最近高点有一定缓冲。 2. 可考虑在信号产生后有确认机制,如价格突破前高点等。 3. 建议参数优化要全面考量多种市场情况。
该策略整体较为简单易用,基于EMA均线产生信号,顺势而为,再辅以ATR指标追踪止损,可以有效控制风险。虽然会有一定假信号,但捕捉主要趋势的能力较强,收益较为稳定,适合作为量化交易的基础策略之一。通过参数优化和功能扩展还具有很大的改进空间,值得深入研究。
