I am currently working on an indicator in pinescript that plots horizontal lines on levels of interest, the value of those levels i put in manually each day. The issue i currently have is that if for example i want to plot lines on NIO at $20 and $21 and then change the chart to for example TSLA, those same levels from NIO also show on the TSLA chart. I need to find a way so the levels from NIO or only plotted on a NIO chart and the levels from TSLA are only plotted on a TSLA chart. I don't have much coding experience so i used an existing code as base, here is how it looks: Code: a1 = input(0, minval=0, type=input.float, title="Horizontal Line 1") b1 = input(false, type=input.bool, title="Highlight Line 1?") c1 = b1 == true ? color.red : color.yellow hline(a1, title="Horizontal Line 1", color=c1, linestyle=hline.style_solid, linewidth=2) plot(a1)
