pine-script - 如何根据之字形外观在 pine 脚本中创建警报？

Question

我正在尝试包含我在 Tradingview 中找到的该指标的警报。当锯齿线出现在蜡烛上方时，我需要一个卖出警报，当它出现在蜡烛下方时，我需要一个买入警报。

以下是该指标的完整 pinescript：

showPatterns = input(true, title='Show Patterns')
showFib0000 = input(title='Display Fibonacci 0.000:', type=bool, defval=true)
showFib0236 = input(title='Display Fibonacci 0.236:', type=bool, defval=true)
showFib0382 = input(title='Display Fibonacci 0.382:', type=bool, defval=true)
showFib0500 = input(title='Display Fibonacci 0.500:', type=bool, defval=true)
showFib0618 = input(title='Display Fibonacci 0.618:', type=bool, defval=true)
showFib0764 = input(title='Display Fibonacci 0.764:', type=bool, defval=true)
showFib1000 = input(title='Display Fibonacci 1.000:', type=bool, defval=true)
