有没有办法从开盘或收盘检测蜡烛的价格+/-某个百分比？

Question

我试图检测看涨/看跌吞没蜡烛，两边都有一点摆动空间，因为价格有时会出现小的差异。 即使蜡烛打开/关闭与之前的打开/关闭相比 +/-.01%，我也想检测到吞没。

//identify bullish/bearish engulfing candles
bullishEC = close > open[1] and open <= close[1] and close[1] < open[1] 
bearishEC = close < open[1] and open >= close[1] and close[1] > open[1]

Answer 1

您可以将 open[1] 和 close[1] 乘以所需的价格百分比，然后进行比较。 例子

bullishEC = close > open[1]*(1-0.01/100) and open <= close[1]*(1+0.01/100) and close[1] < open[1] 
bearishEC = close < open[1]*(1+0.01/100) and open >= close[1]*(1-0.01/100) and close[1] > open[1]
