This is FE fibo expansion that I create using 2 object(P[2]) in array that represent their properties for each direction UP or DOWN.

Here is a class look like:

```class ___
{
public:
int
aa,bb,cc;
double
A,
B,
C;
___():
aa(0),bb(0),cc(0),
A(0.0),B(0.0),C(0.0)
{}
~___() {}
} P[2];
```

Where for each direction they must have 3 prices A, B and C that is upper, lower and a price between upper and lower.
While, aa, bb, and cc are the bar locations for their respective prices A, B and C earlier.

Then, I used the fractal formula and a little modification to determine the 3 points upper, lower and price between them along with its directions.

I use loop from the recent bar location:

```   int i=0;
int m=0,n=0;
bool stop=false;
double hi=0.0,lo=0.0;
//---
A=0.0;
B=0.0;
C=0.0;
for(m=0,n=0,i=0; i<Bars-3&&!stop; i++)
{
hi=(
iHigh(_Symbol,0,i+2)>=iHigh(_Symbol,0,i+0) &&
iHigh(_Symbol,0,i+2)>=iHigh(_Symbol,0,i+1) &&
iHigh(_Symbol,0,i+2)>=iHigh(_Symbol,0,i+3) &&
iHigh(_Symbol,0,i+2)>=iHigh(_Symbol,0,i+4))
?iHigh(_Symbol,0,i+2):0.0;
lo=(
iLow(_Symbol,0,i+2)<=iLow(_Symbol,0,i+0) &&
iLow(_Symbol,0,i+2)<=iLow(_Symbol,0,i+1) &&
iLow(_Symbol,0,i+2)<=iLow(_Symbol,0,i+3) &&
iLow(_Symbol,0,i+2)<=iLow(_Symbol,0,i+4))
?iLow(_Symbol,0,i+2):0.0;
//---
//---
//--------------------------------------------------------------------------------------------------------------------
//--------------------------------------------------------------------------------------------------------------------
if(hi!=0.0)// ------------up------------
{
if(P[1].C!=0.0)
{
if(n==1)
{
if(P[1].C<hi)
{
P[1].B=hi;   //this B[1] dn
P[1].bb=i+2;
n++;
}
else
{
n--;
P[1].C=0.0;
}
}
if(n==2)
{
if(P[1].B<hi&&P[1].C<P[1].B)
{
P[1].B=hi;   //this modify B[1] before A[1] exist
P[1].bb=i+2;
}
}
}
//---
if(P[0].C==0.0)
{
if(m<1)
{
P[0].C=hi;   //innitial C[0] up
P[0].cc=i+2;
m++;
}
}
else
{
if(m==1)
{
if(P[0].C<hi)
{
P[0].C=hi;   //this modify C[0] before B[0] exist
P[0].cc=i+2;
}
}
if(m==2)
{
if(P[0].C<hi)
{
P[0].A=hi;   //this A[0] up
P[0].aa=i+2;
m=0;
stop=true;
}
}
}
}
//else
if(lo!=0.0)// ------------dn------------
{
if(P[0].C!=0.0)
{
if(m==1)
{
if(P[0].C>lo)
{
P[0].B=lo;   //this B[0] up
P[0].bb=i+2;
m++;
}
else
{
m--;
P[0].C=0.0;
}
}
if(m==2)
{
if(P[0].B>lo&&P[0].C>P[0].B)
{
P[0].B=lo;   //this modify B[0]before A[0] exist
P[0].bb=i+2;
}
}
}
//---
if(P[1].C==0.0)
{
if(n<1)
{
P[1].C=lo;   //innitial C[1] dn
P[1].cc=i+2;
n++;
}
}
else
{
if(n==1)
{
if(P[1].C>lo)
{
P[1].C=lo;   //this modify C[1] before B[1] exist
P[1].cc=i+2;
}
}
if(n==2)
{
if(P[1].C>lo)
{
P[1].A=lo;   //this A[1] dn
P[1].aa=i+2;
n=0;
stop=true;
}
}
}
//---
}
//else
//
//---
//---
//---

if((P[0].C==0.0&&P[1].C==0.0)||(hi==0.0&&lo==0.0))
{
continue;
}

}// loop
```

If it found 3 points of either UP or DOWN direction, the loop breaks.

I have to take out the 3 points earlier.

```   if(P[0].A!=0.0&&P[0].B!=0.0&&P[0].C!=0.0)
{
DrawExpansion(tool,"FE ->",Time[P[0].aa],P[0].A,Time[P[0].bb],P[0].B,Time[P[0].cc],P[0].C,-1);
}
//---
if(P[1].A!=0.0&&P[1].B!=0.0&&P[1].C!=0.0)
{
DrawExpansion(tool,"FE ->",Time[P[1].aa],P[1].A,Time[P[1].bb],P[1].B,Time[P[1].cc],P[1].C,1);
}
```

And finally draw using OBJ_EXPANSION object..and I use a single function DrawExpansion(...).

```void DrawExpansion(string name,string label,datetime t1,double p1,datetime t2,double p2,datetime t3,double p3,int fl=0)
{
//---
ObjectDelete(name);
color wrn=(fl>0)?clrSkyBlue:(fl<0)?clrTomato:clrWhite;
if(ObjectFind(0,name)!=0)
ObjectCreate(name,OBJ_EXPANSION,0,t1,p1,t2,p2,t3,p3);
ObjectSet(name,OBJPROP_FIBOLEVELS,5);
ObjectSet(name,OBJPROP_FIRSTLEVEL+0,0.618);
ObjectSet(name,OBJPROP_FIRSTLEVEL+1,1.000);
ObjectSet(name,OBJPROP_FIRSTLEVEL+2,1.618);
ObjectSet(name,OBJPROP_FIRSTLEVEL+3,2.618);
ObjectSet(name,OBJPROP_FIRSTLEVEL+4,4.236);
//---
ObjectSet(name,OBJPROP_LEVELCOLOR,clrMediumPurple);
ObjectSet(name,OBJPROP_LEVELWIDTH,1);
ObjectSet(name,OBJPROP_LEVELSTYLE,0);
ObjectSet(name,OBJPROP_COLOR,wrn);
//---
ObjectSetFiboDescription(name,0,label+"  "+DoubleToStr(0.618*100,1)+"  ");
ObjectSetFiboDescription(name,1,label+"  "+DoubleToStr(1.000*100,1)+"  ");
ObjectSetFiboDescription(name,2,label+"  "+DoubleToStr(1.618*100,1)+"  ");
ObjectSetFiboDescription(name,3,label+"  "+DoubleToStr(2.618*100,1)+"  ");
ObjectSetFiboDescription(name,4,label+"  "+DoubleToStr(4.236*100,1)+"  ");
//---
}```

Here, I use

0.618,

1.000,

1.618,

2.618 and

4.236 level.
