How to bypass "if" operator restriction and draw "hline"

Question

trying to draw (and switch between) three lines above and below my base value. But I can't get it to work because "if" operator unable to use "line". Tried to reference "hline" in "plot" - also failed. I would appreciate your help on how to solve this restriction. https://i.stack.imgur.com/3k5qk.png

indicator("Lines", overlay=true)
base = input.float(title="Base Value", defval=0.76,  step=0.0001)
lineChoice = input.string(title="Buy/Sell", defval = "Buy", options = ["Buy", "Sell", "Buy&Sell"])

if (lineChoice == "Buy")
    hline(base, title='Base', color=color.aqua, linestyle=hline.style_solid, linewidth=2)
    hline(base * 1.03, title='3%', color=color.aqua, linestyle=hline.style_dotted, linewidth=2)
    hline(base * 1.02, title='2%', color=color.aqua, linestyle=hline.style_dashed, linewidth=2)
    hline(base * 1.01, title='1%', color=color.aqua, linestyle=hline.style_dashed, linewidth=2)
    hline(base * 1.004, title='0,4%', color=color.aqua, linestyle=hline.style_dashed, linewidth=2)
else if (lineChoice =="Sell")    
    hline(base, title='Base', color=color.purple, linestyle=hline.style_solid, linewidth=2)
    hline(base * 0.996, title='-0.4%', color=color.purple, linestyle=hline.style_dotted, linewidth=2)

plot (base)

Thank you!!!

Answer 1

I was hoping to get an answer here but had to find a solution myself. Instead of "hline" we need to use "line.new" and that solves everything.
