本策略专注于开盘盘前时段,结合均线和动量指标判断短期趋势,在高动量阶段进行突破交易。属于典型的短线套利策略。
策略原理:
设置盘前交易时段为开盘前1小时内。
计算50周期EMA判断大盘合理价格区间。
SMI指标在区域低点出现向上交叉视为买入信号。
突破EMA均线的收盘价视为止损信号。
设定固定止盈点,目标短线套现。
该策略的优势:
突破短期EMA,可判断当日趋势方向。
SMI指标可确认超卖区域出现反转机会。
回测参数有限,实盘易操作。
该策略的风险:
突破容易形成盘前套牢,须警惕反转。
单日时间段操作,难以应对跳空。
停损幅度偏小,调整不当易止损。
总之,该策略为典型盘前短线策略,通过EMA和SMI指标追捧高动量突破。但盘前套牢风险高,需控制仓位并做好止损。
