该策略是一个基于布林带指标的四小时级别量化交易系统,结合了趋势突破和均值回归的交易理念。策略通过布林带上下轨的突破来捕捉市场动量,同时利用价格回归均值的特性来进行获利了结,并通过止损控制风险。策略采用3倍杠杆,在保证收益的同时也充分考虑了风险控制。
策略的核心逻辑基于以下几个关键要素: 1. 使用20周期的移动平均线作为布林带的中轨,并以2倍标准差作为波动区间 2. 开仓信号:当K线实体(开盘价和收盘价的均值)突破上轨时开多,突破下轨时开空 3. 平仓信号:多头持仓时,如果连续两根K线收盘价和开盘价都低于上轨且收盘价低于开盘价时平仓;空头持仓采用相反逻辑 4. 风险控制:建仓时以当前K线最高/最低点设置止损,确保单笔损失可控
这是一个将布林带指标的趋势跟随和均值回归特性相结合的策略,通过严格的开平仓条件和风险控制措施,实现了在趋势和震荡市场中都能获得稳定收益的目标。策略的核心优势在于其清晰的交易逻辑和完善的风险控制体系,但仍需要注意杠杆使用和市场环境判断等方面的优化,以进一步提高策略的稳定性和收益能力。
