//@version=5
indicator("My script", overlay = true)

if high[2] > high[3]
    if low[3] > low[2]
        long_above=high[2]

if high[2]>high[1]
    if low[2]<low[1]
        short_below=low[2]

plotshape(ta.crossover(close, long_above),style = shape.triangleup)

>Solution :


 //@version=5
indicator("My script", overlay = true)
float long_above = na
float short_below= na
if high[2] > high[3]
    if low[3] > low[2]
        long_above:=high[2]

if high[2]>high[1]
    if low[2]<low[1]
        short_below:=low[2]

plotshape(ta.crossover(close, long_above),style = shape.triangleup)
