Hello everyone.
I want to combine these three indicators.
I look forward to your help.

//FUNCTIONS
//HMA
HMA(_src, _length) => wma(2 * wma(_src, _length / 2) - wma(_src, _length), round(sqrt(_length)))
//EHMA

EHMA(_src, _length) => ema(2 * ema(_src, _length / 2) - ema(_src, _length), round(sqrt(_length)))
//THMA

THMA(_src, _length) => wma(wma(_src,_length / 3) * 3 - wma(_src, _length / 2) - wma(_src, _length), _length)

//SWITCH
Mode(modeSwitch, src, len) =>
modeSwitch == Hma ? HMA(src, len) :
modeSwitch == Ehma ? EHMA(src, len) :
modeSwitch == Thma ? THMA(src, len/2) : na

//COLOR

//PLOT
///< Frame

alertcondition(crossover(MHULL, SHULL), title=Hull trending up., message=Hull trending up.)
alertcondition(crossover(SHULL, MHULL), title=Hull trending down., message=Hull trending down.)
///< Ending Filler
fill(Fi1, Fi2, title=Band Filler, color=hullColor, transp=transpSwitch)
///BARCOLOR
barcolor(color = candleCol ? (switchColor ? hullColor : na) : na)
