如何根据 TP / SL 条件发出买入信号？ 请帮我

Question

'对 Pine Script 很陌生，我很感谢你的帮助。 下面是一个示例代码，它生成“买入”信号。 但是，我想让这些“买入”信号仅在满足“获利”或“止损”条件时才会发生。 任何想法？

在从先前的信号增益中获利后，我想 plot 买入/卖出信号，以免在较小的图表上重新绘制

但我制作的这段代码只显示 19 根蜡烛后的信号

我正在尝试找到一种解决方案，以便在我已经从前一个信号中获得或停止之后出现买入/卖出信号

我的代码没有错误，只是没有做我想要的 function

欢迎任何帮助

这是我的代码

//@version=5
indicator("My script", overlay=true)

var cnt = 0
var startCounting = false

var cnt1 = 0
var startCounting1 = false

bodyMiddle = plot((open + close) / 2, display=display.none)
upTrend = plot(direction < 0 ? supertrend : na, "Up Trend", color = color.green, style=plot.style_linebr)
downTrend = plot(direction < 0? na : supertrend, "Down Trend", color = color.red, style=plot.style_linebr)

fill(bodyMiddle, upTrend, color.new(color.green, 90), fillgaps=false)
fill(bodyMiddle, downTrend, color.new(color.red, 90), fillgaps=false)

//Stoch Inputs

Answer 1

1. 声明var allowNewPosition = true
2. 更改条件： canlong = long and cnt > 19 and allowNewPosition and canshort = short and cnt1 > 19 and allowNewPosition
3. 之后在某处插入以下内容：

    if canlong or canshort
        allowNewPosition:= false

   在您收到买入/卖出信号后激活您的封锁条件
4. 最后，在您知道您是否有 TP/SL 之后，解除对新仓位的封锁：

    if longSLhit or shortSLhit or longTPhit or shortTPhit
        allowNewPosition:= true
