//Chande's Momentum Oscillator II
periods=Param("Periods",14,5,30,1);
//{define an up Day AND down Day}
upday=IIf(C>Ref(C,-1),C-Ref(C,-1),0);
downday=IIf(Ref(C,-1)> C,Ref(C,-1)-C,0);
//{Sum up the up AND down days over the given period}
sumup=Sum(upday,periods);
sumdown=Sum(downday,periods);
//{define the CMO}
CD=100*(sumup-sumdown)/(sumup+sumdown);
 
/////////////////////////////////////
 
//Momentum Index
PD= Param("Lookback Period",30, 5, 220, 1);
MI= {Chande Momentum Osc (C,PD)}
((Sum(IIf(Close,>,Ref(Close,-1), (Close-Ref(Close,-1)),0),pd)) -
(Sum(IIf(Close,<,Ref(Close,-1), (Ref(Close,-1)- Close),0),pd))) /
((Sum(IIf(Close,>,Ref(Close,-1), (Close-Ref(Close,-1)),0),pd) +
(Sum(IIf(Close,<,Ref(Close,-1), (Ref(Close,-1)- Close),0),pd))))*100; // problem start here
