我在 tradingview 脚本页面上找到了一个开源代码，我在这段代码中添加了 TP2 和 TP3 价格点，但是代码中有一个代码会在价格达到 tp 和 sl 点时发出警告，我知道如何乘以它，所以我需要帮助。
这是代码

正如您在代码中看到的，当价格达到 tp 和 sl 时，有一个代码会发出警报。
这是我需要帮助的地方
//remove first bar for SL/TP (you can't enter a trade at bar close THEN hit your SL on that same bar)
longBar1 = barssince(long_last)
longBar2 = longBar1 >= 1 ? true : false
shortBar1 = barssince(short_last)
shortBar2 = shortBar1 >= 1 ? true : false
//check for SL hit during a bar
longSLhit = long_short==1 and longBar2 and low < longStop
plotshape(longSLhit, style=shape.labelup, location=location.belowbar, color=color.gray, size=size.tiny, title="Long SL", text=" Long SL", textcolor=color.white)
shortSLhit = long_short==-1 and shortBar2 and high > shortStop
plotshape(shortSLhit, style=shape.labeldown, location=location.abovebar, color=color.gray, size=size.tiny, title="Short SL", text=" Short SL", textcolor=color.white)
//check for TP hit during bar
longTPhit = long_short==1 and longBar2 and high > longTake
plotshape(longTPhit, style=shape.labeldown, location=location.abovebar, color=color.purple, size=size.tiny, title="Long TP", text="Long TP", textcolor=color.white)
shortTPhit = long_short==-1 and shortBar2 and low < shortTake
plotshape(shortTPhit, style=shape.labelup, location=location.belowbar, color=color.purple, size=size.tiny, title="Short TP", text="Short TP", textcolor=color.white)
//reset long_short if SL/TP hit during bar
long_short := (long_short==1 or long_short==0) and longBar2 and (longSLhit or longTPhit) ? 0 : (long_short==-1 or long_short==0) and shortBar2 and (shortSLhit or shortTPhit) ? 0 : long_short

我在这部分找不到如何多路复用 longTPHit 或 shortTPHit 我需要你的帮助
