创建看涨吞没蜡烛脚本

Question

刚开始使用 Pine Script 和一般编码。我发现了几个开源脚本，它们能够在出现吞没看涨蜡烛时发出买入信号。有没有办法对其进行编码，以便必须首先有 3 根看跌蜡烛，然后是一根看涨蜡烛才能发出买入信号？图 1 显示了我想要的东西，有 3 支红色蜡烛，然后发出买入信号。图 2 显示只有一根红色蜡烛，然后是一根表示买入的看涨蜡烛。

Answer 1

threeRed = close[1] < open[1] and close[2] < open[2] and close[3] < open[3]

oneRed = close[1] < open[1]

bullishEng = close > open and close > max(open[1], close[1])

buySignal1 = oneRed and bullishEng and not threeRed
buySignal3 = threeRed and bullishEng
