// Chande's Momentum Oscilator:
//
// ((Su - Sd) / (Su + Sd)) * 100
//
//      - Su is the sum of the momentum of up days in the period under analysis
//      - Sd is the sum of the momentum of down days in the period under analysis.
//      - The default period is the last 9 days.
// }

// Input : {
p = input(24, title="Period:")
hl = input(40, title="Overbought:")
ll = input(-40, title="Oversold:")
// }

// Function : {
s = close
Su = sma(close > open ? s - s[1] : 0, p)
Sd = sma(close < open ? abs(s - s[1]) : 0, p)

cmo = ((Su - Sd)/(Su + Sd))*100
ma1 = ema(cmo, 12)
ma2 = ema(ma1, 24)
ma3 = ema(ma2, 48)
// }

// Output : {
