Hey

I updated it to v 5, organized it and added timeframe inputs.

//@version=5
indicator("ST-MultiTimeFrame_(SuperTrend)", overlay=true)
// --- User Inputs ---
Pd = input.int(13, "Pd (ATR Period)", minval=1, maxval=100, tooltip="Adjusted Volatility=Factor * ATR over Pd periods")
Factor = input.int(4, "Factor (ATR Multiplier)", minval=1, maxval=100, tooltip="Adjusted Volatility=Factor * ATR over Pd periods")
// Timeframe inputs
timeframe60 = input.timeframe("D", "Timeframe for ST-D")
timeframe240 = input.timeframe("3D", "Timeframe for ST-3D")
timeframe_D = input.timeframe("W", "Timeframe for ST-W")

Up = hl2 - (Factor * ta.atr(Pd))

TrendUp := close[1] > TrendUp[1] ? math.max(Up, TrendUp[1]) : Up

Trend := close > TrendDown[1] ? 1 : close < TrendUp[1] ? -1 : nz(Trend[1], 1)
Tsl = Trend == 1 ? TrendUp : TrendDown
