The Chande Momentum Oscillator (CMO) attempts to capture the momentum of the instrument. The indicator oscillates between -100 and 100 with overbought level of 50 and oversold level of -50.
\[CMO = \left (\frac{PosSum - NegSum}{PosSum + NegSum} \right )\times 100\]
where:
\[PosSum = \sum (Close_{current}\;-\;Close_{previous})\;when\;(Close_{current}\;-\;Close_{previous}) > 0\]
\[NegSum = \sum \left | (Close_{current}\;-\;Close_{previous}) \right |\;when\;(Close_{current}\;-\;Close_{previous}) < 0\]
