如何在Tradeview上自动绘制目标

Question

我正在尝试在tradingview上自动绘制目标，就像这张图片

，

但是我失败了，TP会重复出现几次。

有人可以帮助我吗？

plotshape(  (close>TP1_value)  , title="TP1_Reached", style=shape.arrowup, location=location.belowbar, color=green, transp=0, text="TP1_Reached", textcolor=green, size=size.large)

Answer 1

您的问题是，close>TP1_value对多个小节都是正确的。如果只想绘制一次，则可以使用一个变量。

//@version=4
study("My Script", overlay=true)

TP1_value = input(title="Take Profit Price", defval=10000)

var isTP1reached = false  // Use this variable to see if TP1 hass already been reached

takeProfit1 = not isTP1reached and (close > TP1_value)  // If not already reached TP1 and TP condition is true

if (takeProfit1)
    isTP1reached := true

plotshape(series=takeProfit1, title="Take Profit 1", text="Take Profit 1", style=shape.triangleup, location=location.belowbar, color=color.green, size=size.small)

从上图可以看到，它仅绘制一次。当然，您需要根据需要重置变量，以便再次使用它。
