Squelch Control Indicator
Hi,
I have the EasyLanguage code to implement the Squelch Control as a Paintbar and I need someone to write an indicator for MT4. This indicator was writen by John Ehlers. I think it's very useful.
Inputs: Price((H+L)/2),
Squelch(20);
Vars: InPhase(0),
Quadrature(0),
Phase(0),
DeltaPhase(0),
count(0),
InstPeriod(0),
Period(0);
If CurrentBar > 5 then begin
{Compute InPhase and Quadrature components}
Value1 = Price - Price[6];
Value2 =Value1[3];
Value3 =.75*(Value1 - Value1[6]) + .25*(Value1[2] - Value1[4]);
InPhase = .33*Value2 + .67*InPhase[1];
Quadrature = .2*Value3 + .8*Quadrature[1];
{Use ArcTangent to compute the current phase}
If AbsValue(InPhase +InPhase[1]) > 0 then Phase = ArcTangent(AbsValue((Quadrature+Quadrature[1]) / (InPhase+InPhase[1])));
{Resolve the ArcTangent ambiguity}
If InPhase < 0 and Quadrature > 0 then Phase = 180 - Phase;
If InPhase < 0 and Quadrature < 0 then Phase = 180 + Phase;
If InPhase > 0 and Quadrature < 0 then Phase = 360 - Phase;
{Compute a differential phase, resolve phase wraparound, and limit delta phase errors}
DeltaPhase = Phase[1] - Phase;
If Phase[1] < 90 and Phase > 270 then DeltaPhase = 360 + Phase[1] - Phase;
If DeltaPhase < 1 then DeltaPhase = 1;
If DeltaPhase > 60 then Deltaphase = 60;
{Sum DeltaPhases to reach 360 degrees. The sum is the instantaneous period.}
InstPeriod = 0;
Value4 = 0;
For count = 0 to 40 begin
Value4 = Value4 + DeltaPhase[count];
If Value4 > 360 and InstPeriod = 0 then begin
InstPeriod = count;
end;
end;
{Resolve Instantaneous Period errors and smooth}
If InstPeriod = 0 then InstPeriod = InstPeriod[1];
Period = .25*InstPeriod + .75*Period[1];
If Period < Squelch then begin
Plot1(High,"High");
Plot2(Low,"Low");
end;
end;
