双重底部反转均线DCA网格策略主要应用均线价格反转和DCA策略实现网格逐步建仓。它根据双重底部反转形态来判断反转机会。一旦触发反转形态后,使用多个不同价格的委托单,结合DCA建立逐步网格仓位。
该策略首先判断K线是否出现连续两个收盘价相等的底部,这被称为“双重底”。如果检测到双重底,则认为可能出现价格反转机会。此时,策略会在底部附近设置多笔限价委托单,这些委托单的价格会按照ATR和波动率计算,形成一个网格区间。这实现了DCA的效果,可以让交易者在反转后的不同价格点逐步建仓。
具体来说,首先通过ta.atr计算最近14根K线的ATR指标,然后结合最近5根K线计算价格波动率,这是用来确定网格区间的主要参数。网格区间分为4个价格点,分别是底部价格+波动率、底部价格+0.75倍波动率,以此类推。当触发双重底条件后,按这个计算公式在对应价格设置4笔限价委托单,每笔数量相等。未成交的挂单会在设置的蜡烛数后自动撤单。
此外,策略还会设置止损位和止盈位。止损价格为双重底的最低价-最小跳动位,止盈价格为入场价+ATR指标的5倍。当仓位不为0时,这两个价格会实时更新。
该策略具有以下优势:
主要风险有:
该策略还可以从以下几个方向进行优化:
双重底部反转均线DCA网格策略综合运用了价格形态、均线指标、网格交易等多种技术手段。它具有判断时点精准、成本可控、回撤有保护等优点。该策略优化空间还很大,值得深度研究与应用。如果参数调整得当,在震荡行情中可以获得不错的效果。
