mismatched input 'if' expecting 'end of line without line continuation'

Question

I'm having this "mismatched input 'if' expecting 'end of line without line continuation'" error in pinescript with the following block of code:

arrow(direction, bar, color) =>
    if direction == "up"
        plotchar(bar, high, "\u2191", color, size = size.normal)
    else if direction == "down"
        plotchar(bar, low, "\u2193", color, size = size.normal)

Answer 1

You cannot use plot*() functions in a local loop.

You can apply your condition to the series argument of your plot() call as a workaround so it would conditionally plot.
