创建一个看涨吞没蜡烛脚本

Question

刚开始使用 Pine Script 和编码。我发现了几个开源脚本，它们能够在出现吞没的看涨蜡烛时发出买入信号。有没有办法对其进行编码，以便必须先有 3 根看跌蜡烛，然后再用一根看涨蜡烛来表示买入？图 1 显示了我想要的 3 根红色蜡烛，然后发出买入信号。图 2 显示只有 1 根红色蜡烛，然后有一根看涨蜡烛表示买入。

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
