Conversion of Bollinger Bands x3 with Fill

Please can anyone convert the following indicator: //@version=6 indicator(shorttitle=”BBx3″, title=”Bollinger Bands x3 with Fill + HMA + Dynamic Width Colors”, overlay=true, timeframe=””, timeframe_gaps=true) // === Inputs === length = input.int(20, minval=1, title=”Length”) maType = input.string(“SMA”, “Basis MA Type”, options=[“SMA”, “EMA”, “SMMA (RMA)”, “WMA”, “VWMA”, “HMA”]) src = input(close, title=”Source”) mult1 = input.float(1.0, minval=0.001, maxval=50, title=”StdDev Multiplier Band 1″) mult2 = input.float(2.0, minval=0.001, maxval=50, title=”StdDev Multiplier Band 2″) mult3 = input.float(3.0, minval=0.001, maxval=50, title=”StdDev Multiplier Band 3″) fillColor1 = input.color(color.new(color.blue, 85), “Fill Color Between Band 1 & 2 (Expanding)”) fillColor2 = input.color(color.new(color.purple, 85), “Fill Color Between Band 2 & 3 (Expanding)”) fillColorNarrow = input.color(color.new(color.gray, 85), “Fill Color (Narrowing)”) showBand1 = input.bool(true, “Show Band 1 (±1σ)”) showBand2 = input.bool(true, “Show Band 2 (±2σ)”) showBand3 = input.bool(true, “Show Band 3 (±3σ)”) showFill12 = input.bool(true, “Fill Between Band 1 & 2”) showFill23 = input.bool(true, “Fill Between Band 2 & 3”) offset = input.int(0, “Offset”, minval = -500, maxval = 500, display = display.data_window) // === MA Functions === hma(src, len) => wma1 = ta.wma(src, len) wma2 = ta.wma(src, len / 2) ta.wma(2 * wma2 – wma1, math.round(math.sqrt(len))) ma(source, length, _type) => switch _type “SMA” => ta.sma(source, length) “EMA” => ta.ema(source, length) “SMMA (RMA)” => ta.rma(source, length) “WMA” => ta.wma(source, length) “VWMA” => ta.vwma(source, length) “HMA” => hma(source, length) // === Calculations === basis = ma(src, length, maType) dev = ta.stdev(src, length) upper1 = basis + mult1 * dev lower1 = basis – mult1 * dev upper2 = basis + mult2 * dev lower2 = basis – mult2 * dev upper3 = basis + mult3 * dev lower3 = basis – mult3 * dev // === Band Widths === width1 = upper1 – lower1 width2 = upper2 – lower2 width3 = upper3 – lower3 // === Narrowing Flags === narrowing1 = width1 < width1[1] narrowing2 = width2 < width2[1] narrowing3 = width3 < width3[1] // === Dynamic Line Colors === colorU1 = narrowing1 ? color.gray : color.lime colorL1 = narrowing1 ? color.gray : color.lime colorU2 = narrowing2 ? color.gray : color.orange colorL2 = narrowing2 ? color.gray : color.orange colorU3 = narrowing3 ? color.gray : color.red colorL3 = narrowing3 ? color.gray : color.red // === Dynamic Fill Colors === fillColorBand12 = narrowing2 ? fillColorNarrow : fillColor1 fillColorBand23 = narrowing3 ? fillColorNarrow : fillColor2 // === Plot Lines === plot(basis, “Basis”, color=#000000, offset=offset) pU1 = plot(showBand1 ? upper1 : na, “Upper 1σ”, color=showBand1 ? colorU1 : na, offset=offset) pL1 = plot(showBand1 ? lower1 : na, “Lower 1σ”, color=showBand1 ? colorL1 : na, offset=offset) pU2 = plot(showBand2 ? upper2 : na, “Upper 2σ”, color=showBand2 ? colorU2 : na, offset=offset) pL2 = plot(showBand2 ? lower2 : na, “Lower 2σ”, color=showBand2 ? colorL2 : na, offset=offset) pU3 = plot(showBand3 ? upper3 : na, “Upper 3σ”, color=showBand3 ? colorU3 : na, offset=offset) pL3 = plot(showBand3 ? lower3 : na, “Lower 3σ”, color=showBand3 ? colorL3 : na, offset=offset) // === Fill Zones with Dynamic Color === fill(pU1, pU2, color=showFill12 ? fillColorBand12 : na, title=”Fill Upper 1↔2σ”) fill(pL1, pL2, color=showFill12 ? fillColorBand12 : na, title=”Fill Lower 1↔2σ”) fill(pU2, pU3, color=showFill23 ? fillColorBand23 : na, title=”Fill Upper 2↔3σ”) fill(pL2, pL3, color=showFill23 ? fillColorBand23 : na, title=”Fill Lower 2↔3σ”)
