The formula calculates Fib Levels between fractals. The Fib Levels are worked out from the most recent fractal to the one before it. I can’t remember where I found the fractal algorith, but it’s one a few AFLs throughout the net. Thanks to the person/people who put it up there.

PHigh = H > Ref(HHV(H,nbar),-1) AND Ref(HHV(H,nbar),nbar) <= H;
PHighPrice = ValueWhen(PHigh,H);
PLow = L < Ref(LLV(L,nbar),-1) AND Ref(LLV(L,nbar),nbar) >= L;
PLowPrice = ValueWhen(PLow,L); 

Bear = ValueWhen(PHigh, DateTime());
Bull = ValueWhen(PLow, DateTime());

PlotShapes(shapeSmallCircle*PLow,colorGreen,0,L,-10);
PlotShapes(shapeSmallCircle*PHigh,colorRed,0,H,10);

//Plot(PLowPrice, "Fractal Low", colorGreen, styleDots | styleNoLine);
//Plot(PHighPrice, "Fractal High", colorRed, styleDots | styleNoLine);

phase = IIf(bull > bear, 0, 1);

//Fib Level Calculation
//If previous fractal was down fractal, then Fib Level is worked out
//by subtracting the down fractal from the up fractal and vice versa
