如何根据 TP / SL 条件发出买入信号？

Question

我对 Pine Script 还是很陌生，在这里非常感谢您的帮助。 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？

//@version=5
indicator("My script", overlay=true)
EMA1 = ta.ema(close, 20)
EMA2 = ta.ema(close, 50)
Buy = ta.crossover(EMA1, EMA2)
TPline = ta.valuewhen(Buy, close * 1.05, 0)
SLline = ta.valuewhen(Buy, close * 0.95, 0)
TakeProfit = ta.crossover(high, TPline)
StopLoss = ta.crossunder(low, SLline) 

plot(TPline, color=color.orange, linewidth=2)
plot(SLline, color=color.aqua, linewidth=2)
plotshape(Buy, title = "Buy", style=shape.labelup, color=color.olive, location = location.belowbar, text ="Buy", textcolor = color.white)
plotshape(TakeProfit, title = "TakeProfit", style=shape.labeldown, color=color.green, location = location.abovebar, text ="TP", textcolor = color.white)
plotshape(StopLoss, title = "StopLoss", style=shape.labelup, color=color.red, location = location.belowbar, text ="SL", textcolor = color.white)

这也是一个屏幕截图：屏幕截图，指向冗余买入信号的箭头

Answer 1

plotshape(TakeProfit or StopLoss ? Buy : na , title = "Buy", style=shape.labelup, color=color.olive, location = location.belowbar, text ="Buy", textcolor = color.white)

或者，与

// put the `Buy` variable after declaration of `TakeProfit` and `StopLoss` variables 
Buy = ta.crossover(EMA1, EMA2) and TakeProfit and StopLoss

plotshape(Buy, title = "Buy", style=shape.labelup, color=color.olive, location = location.belowbar, text ="Buy", textcolor = color.white)
