双向追Momentum止盈止损策略

概述

本策略是基于TradingView内置的连续上涨/下跌策略进行扩展。它具有灵活的策略方向设置,可以进行反向交易。同时,集成了摆动高点/低点、ATR止损和追踪止损等多种止损方式,以及对应的止盈设置。这使得该策略在保持原有交易信号的基础上,获得了更好的风险管理。

策略原理

该策略主要通过判断K线的连续上涨或下跌次数,产生买入和卖出信号。用户可以设置买入信号产生所需要的连续上涨K线数量,以及卖出信号所需要的连续下跌K线数量。

同时,策略增加了是否反转交易的设置。开启反转交易后,本来的买入信号会变成卖出信号,卖出信号也会变成买入信号,这样就完成了交易反转。

在进入和退出方面,策略支持直接反向平仓,这样可以减少无仓位时无法交易的情况。

在止损和止盈方面,策略提供了摆动高点/低点、ATR以及策略内置三种可选择的止损方式。止损方式会结合持仓方向,自动选择最低谷或最高峰作为激进止损位,或者根据ATR动态确定止损价格。止盈设置则以策略入场价为基准,设置固定倍数的止盈距离。

如果启用追踪止损,策略可在亏损时加大止损间距,在盈利时缩小止损间距,实现自动追踪。

优势分析

该策略最大的优势在于配置灵活,可以适应不同市况,具体优势如下:

  1. 可设置买卖筛选参数,适应趋势和震荡行情
  2. 支持反转交易,可根据需要选择方向
  3. 设置直接反向开仓,可减少无仓位期
  4. 集成多种止损方式,可按需要选择
  5. 可启用追踪止损,自动止损

风险分析

该策略主要风险在于连续K线设置过多可能导致遗漏交易机会,以及止损设置过于激进带来亏损扩大的风险。针对风险建议如下:

  1. 调整上涨/下跌K线数量参数,不能过于激进
  2. 测试不同的止损方式,选择最适合的
  3. 追踪止损要谨慎设置,避免亏损过大

优化方向

本策略还有进一步优化的空间:

  1. 可以基于ATR或波动率等指标动态调整上涨/下跌K线数量
  2. 可以测试不同持仓时间下的止损止盈比例参数效果
  3. 可以设置Open过滤,避免假突破
  4. 可以添加其他辅助指标判断,提高信号质量

总结

本策略对基准策略进行了有益的扩展,使其可以更好地控制风险,获得更加灵活的交易方式。这是一种易于优化和实盘的有效Momentum策略。
