有沒有辦法從開盤或收盤檢測蠟燭的價格+/-某個百分比？

Question

我試圖檢測看漲/看跌吞沒蠟燭，兩邊都有一點擺動空間，因為價格有時會出現小的差異。 即使蠟燭打開/關閉與之前的打開/關閉相比 +/-.01%，我也想檢測到吞沒。

//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

您可以將 open[1] 和 close[1] 乘以所需的價格百分比，然后進行比較。 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]
