概述
突破回调交易策略通过计算价格的绝对强度指标和MACD指标,实现在特定趋势下的突破回调交易,属于短线交易策略。该策略综合多个指标对大趋势、中期趋势和短期趋势进行判断,通过趋势同向且指标互补确认信号,进行趋势跟踪交易。
策略原理
该策略主要基于价格绝对强度指标和MACD指标实现突破回调交易。首先计算价格的9周期、21周期和50周期EMA,判断大趋势方向;然后计算价格的绝对强度指标,反映短期调整力度;最后计算MACD指标判断短期趋势方向。当大趋势为上涨,且短期出现调整时买入;当大趋势为下跌,且短期出现反弹时卖出。
具体来说,品种大趋势为上涨需满足9日EMA高于21日EMA,21日EMA高于50日EMA。短期调整判断标准为绝对强度指标差值低于0,MACDDIFF小于0。品种大趋势为下跌需满足9日EMA低于21日EMA,21日EMA低于50日EMA。短期反弹判断标准为绝对强度指标差值高于0,MACDDIFF高于0。
优势分析
该策略具有以下优势:
- 结合大趋势和短期调整,避免假突破
- 多个指标组合使用,可靠性较高
- 绝对强度指标反映调整力度,判断回调质量
- MACD可判断短期趋势和超买超卖区域
风险分析
该策略也存在一些风险:
- 大趋势判断错误,可能导致交易失败
- 回调时间和力度判断错误,可能无效回调
- 极端行情下指标发散,产生错误信号
针对以上风险,可通过优化参数,判断不同周期指标;调整持仓规则,控制单笔亏损;结合更多指标过滤信号,提高准确率等方法进行改进。
优化方向
该策略可从以下几个方面进行优化:
- 测试更多指标的组合,寻找更匹配的交易策略
- 优化指标参数,提高指标的敏感性
- 调整止损方式,降低单笔亏损最大值
- 增加过滤条件,在更有效的区域发出信号
- 结合更多时间周期指标判断,提高判断准确性
总结
综上所述,突破回调交易策略整体是一个较为稳定的短线交易策略。它结合大中短多重趋势判断,避免在震荡行情中错误交易。同时指标组合使用也提高了判断的准确性。通过后续的测试和优化,该策略可以成为一个值得长期持有的稳定策略。
