[amibroker] I tried this P&F code but........

["cassianoqs" <cassianoqs@xxxxxxxxx>]

I tried this P&F code but I get different results from stockcharts or
Bull's-Eye Broker. What's wrong with this Percentage Scaling Method ???


//code start here

SetBarsRequired(100000,100000);

//Size for P&F boxes

Bbb = Param("Box ", 1, 0.2, 10, 0.1);
box=exp(log(C))/100*bbb;

HX = round((H/box)*10)/10;
LX = round((L/box)*10)/10;
RH = floor(HX);
FL = ceil(LX);


// initialize first element
j = 0;

Reverse = 3;                      // reversal requirement

PFC[j] = FL[0];
PFO[j] = PFC[j] + 1;
down = 1;                  // By default the first bar is a down bar.
up = 0;
swap = 0;

// perform the loop that produces PF Chart
for( i = 1; i < BarCount; i++ )
{

 if( FL[i] <= PFC[j]-1 && down)         //continue down
 {
  PFC[j] = FL[i];
  PFO[j] = PFC[j] + 1;
 }
 else
 {
  if( RH[i] >= PFC[j] + Reverse && down)  //Change direction to up
  {
   j++;
   swap = 1;
   PFC[j] = RH[i];
   PFO[j] = PFC[j]-1;
  }
 }
 if( RH[i] >= PFC[j] + 1 && up)         //Continue up
 {
  PFC[j] = RH[i];
  PFO[j] = PFC[j] - 1;
 }
 else
 {
  if( FL[i] <= PFC[j] - Reverse && up)   //Change direction to down
  {
   j++;
   PFC[j] = FL[i];
   PFO[j] = PFC[j] + 1;
   swap = 1;
  }
 }
 if( swap )
 {
  swap = 0;
  if( up )
  {
   up = 0;
   down = 1;
  }
  else
  {
   up = 1;
   down = 0;
  }
 }
}
delta = BarCount - j-1;


PFO = Ref( PFO, -delta );
PFC = Ref( PFC, -delta );

// High-Low range sets the height of the P&F bar
H = IIf(Ref(PFC,-1)>Ref(PFO,-1),Ref(HHV(PFC,1),-1)-1,Max(PFO,PFC))*Box;
L = IIf(Ref(PFC,-1)<Ref(PFO,-1),Ref(LLV(PFC,1),-1)+1,Min(PFO,PFC))*Box;
O =
IIf(Ref(PFC,-1)>Ref(PFO,-1),Ref(HHV(PFC,1),-1)-1,IIf(Ref(PFC,-1)<Ref(PFO,-1),Ref(LLV(PFC,1),-1)+1,PFO))*Box;

// the difference between Open AND Close should be set to box size
// the sign decides if X or O are plotted
C = O + Box * IIf( PFC > PFO, 1,-1);

GraphXSpace = 2;
Title ="P&F  " + Name()+ "  PF HiLo, H: " + H+ ", L: " + L+", Box: "+
box + ", Reversal: " + reverse;


Plot( C, "P&F Chart Close", IIf( PFC > PFO, colorBlue, colorRed ),
styleNoLabel+stylePointAndFigure);
