概述
本策略通过计算快速移动平均线和慢速移动平均线,并结合抛物线指标进行买卖判断,属于趋势跟踪类型策略。当快速移动平均线上穿慢速移动平均线时做多;当快速移动平均线下穿慢速移动平均线时做空。同时结合抛物线指标过滤假突破。
策略原理
- 计算快速移动平均线和慢速移动平均线。移动平均线参数可以自定义。
- 比较两条移动平均线,判断市场趋势方向。当快速移动平均线上穿越慢速移动平均线时,判断为多头市场;当快速移动平均线下穿越慢速移动平均线时,判断为空头市场。
- 结合收盘价与移动平均线关系作为进一步确认。只有当快速线上穿慢速线,且收盘价高于快速线时,才产生买入信号;只有当快速线下穿慢速线,且收盘价低于快速线时,才产生卖出信号。
- 使用抛物线指标过滤假突破。只有快速线上穿慢速线,且收盘价高于快速线,且股价高于抛物线时,才最终产生买入信号;反之亦然。
- 根据最大承受损失设定止损线。结合ATR指标计算具体的止损价
策略优势
- 利用移动平均线判断市场趋势方向,避免在无明确方向的盘整市场频繁交易
- 双重过滤条件可有效避免常见的假突破问题
- 结合止损策略有效控制单笔亏损
策略风险
- 指标策略容易产生虚假信号
- 未考虑货币风险
- 可能错过初期不同方向的行情
针对以上问题,可以从以下几个方面进行优化 1. 优化移动平均线参数,使其更贴合具体品种 2. 可以结合其他指标或模型进行信号过滤 3. 考虑实时对冲或自动转换券商账户的货币风险
优化方向
- 优化移动平均线参数,更好捕捉趋势
- 增加模型组合,提高信号准确性
- 多时间周期验证,避免被套
- 优化止损策略,提高策略稳定性
总结
本策略属于典型的双移动平均线以及指标组合趋势跟踪策略。通过比较快慢两条移动平均线方向,判断市场趋势;并结合多种过滤指标避免假信号,从而产生交易信号。同时,策略具备止损功能以控制单笔亏损。优点是策略逻辑简单清晰,容易理解实现,可根据需要灵活优化。缺点是作为粗略趋势判断工具,信号准确性有待提高,可通过引入机器学习等高级模型进行优化。
