Pinescript情节问题
当我的职位“ pos”为= -1（卖出）或位置为= 1（买）时，我需要编辑代码以绘制买入/出售信号位置从红色更改为绿色，反之亦然，请注意：我的pinescript版本是v1，
color = pos == -1 ? red: pos == 1 ? green : blue
plotshape(color , title="Buy", style=shape.labelup, location=location.belowbar, size=size.normal, text="Buy", transp=0, textcolor = white, color=green, transp=0)
plotshape(color , title="Sell", style=shape.labeldown, location=location.abovebar, size=size.normal, text="Sell", transp=0, textcolor = white, color=red, transp=0)
I need to edit my code to plot a buy/sell signal when my position "pos" is =-1 (sell) or the position is = 1 (buy) but the problem is plotting several times I need to plot only every time the position is changed from red to green or vise versa, Note: My Pinescript version is v1,
color = pos == -1 ? red: pos == 1 ? green : blue
plotshape(color , title="Buy", style=shape.labelup, location=location.belowbar, size=size.normal, text="Buy", transp=0, textcolor = white, color=green, transp=0)
plotshape(color , title="Sell", style=shape.labeldown, location=location.abovebar, size=size.normal, text="Sell", transp=0, textcolor = white, color=red, transp=0)

首先，找出位置是否在当前栏上更改。
然后使用这些变量来绘制形状。
First, find out if the position changed on the current bar.
Then use these variables to plot your shape.
