Type : Indicator, Name : I-Q IFM

Inputs: Price((H+L)/2);
Vars: Imult(.635),
Qmult (.338),

If CurrentBar > 8 then begin

Re = .2*(InPhase*InPhase[1] + Quadrature*Quadrature[1]) + .8*Re[1];
Im = .2*(InPhase*Quadrature[1] — InPhase[1]*Quadrature) + .8*Im[1];
If Re <> 0 then DeltaPhase = ArcTangent(Im/Re);

{Sum DeltaPhases to reach 360 degrees. The sum is the instantaneous period.}

For count = 0 to 50 begin

If InstPeriod = 0 then InstPeriod = InstPeriod[1];
