不匹配的输入“如果”期望“没有行继续的行尾”

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.
