Example 1

//@version=6
indicator("Pine Script® Supertrend")[supertrend, direction] = ta.supertrend(3, 10)
plot(direction < 0 ? supertrend : na, "Up direction", color = color.green, style=plot.style_linebr)
plot(direction > 0 ? supertrend : na, "Down direction", color = color.red, style=plot.style_linebr)// The same on Pine Script®pine_supertrend(factor, atrPeriod) => src = hl2 atr = ta.atr(atrPeriod)
upperBand = src + factor * atr lowerBand = src - factor * atr prevLowerBand = nz(lowerBand[1])
prevUpperBand = nz(upperBand[1])
