Question

我正在尝试在指定条件下绘制标识符；但是，在找到指定条件的第一个匹配项（H2_RG-如下）之后，我无法停止脚本。

//@version=4
study("Optimus Prime", overlay=true, scale=scale.none)

//H0_RG conditions and declarations
H0_RG = open > close

//H1_RG conditions and declarations
H1_RG = H0_RG[1] and open < close

//H2_RG conditions and declarations
H2_RG = high[barssince(H1_RG)] < high and low[barssince(H1_RG)] <= low

plotshape(H1_RG, color=color.red, style=shape.arrowdown)
plotshape(H2_RG, color=color.yellow, style=shape.arrowdown)

使用此脚本，我绘制了多个H2_RG事件，但只希望在H1_RG之后的第一个事件发生。任何帮助将不胜感激。

使用一个变量来指示条件是否以前发生过。然后在您的H2_RG条件下检查该变量的值。

以下代码只会绘制一次H2_RG。

//@version=4
study("Optimus Prime", overlay=true, scale=scale.none)

var isH2occured = false

//H0_RG conditions and declarations
H0_RG = open > close

//H1_RG conditions and declarations
H1_RG = H0_RG[1] and open < close

//H2_RG conditions and declarations
H2_RG = not isH2occured and high[barssince(H1_RG)] < high and low[barssince(H1_RG)] <= low

if (H2_RG)
    isH2occured := true

plotshape(H1_RG, color=color.red, style=shape.triangledown, size=size.small)
plotshape(H2_RG, color=color.yellow, style=shape.triangledown, size=size.small)

如何保留第一个事件并删除所有其他后续事件？
