该策略通过计算价格的标准差,判断价格是否出现异常大幅波动。当价格出现异常大幅波动时,则判断为价格反转的机会,采取反向操作。
该策略主要使用两个指标:
wvf = ((highest(close, pd)-low)/(highest(close, pd)))*100
sDev = mult * stdev(wvf, bbl)
midLine = sma(wvf, bbl)
lowerBand = midLine - sDev
upperBand = midLine + sDev
其中,wvf 是价格波动率,sDev 是标准差,midLine 是平均线,lowerBand 和 upperBand 分别是下限线和上限线。当价格超过上限线,则认为出现异常波动。
fastup = rma(max(change(close), 0), 7)
fastdown = rma(-min(change(close), 0), 7)
fastrsi = fastdown == 0 ? 100 : fastup == 0 ? 0 : 100 - (100 / (1 + fastup / fastdown))
当RSI低于某一数值时,表示价格处于超卖状态,可能出现反弹。当RSI超过某一数值时,表示价格处于超买状态,可能出现回落。
该策略的入场和出场逻辑如下:
多仓入场:当价格超过上限线或波动率超过阈值,且RSI低于某一数值时,做多。
空仓入场:当价格超过上限线或波动率超过阈值,且RSI超过某一数值时,做空。
出场条件:开仓方向与K线实体方向相反时平仓。
该策略通过计算价格波动率的标准差,判断价格是否出现异常波动,从而捕捉反转机会。在入场时机选择上,则结合RSI指标判断价格的超买超卖状态,提高精确度。在止损方式上采用简单的实体方向止损。整体来说,该策略利用统计数据判断异常波动,效果较好,但需要进一步优化参数,提高稳定性。如果能够合理优化止损机制,降低亏损,该策略的效果会更好。
