Normalize The Price Like Normalize Double

[Brian Lillard]

double dblNormPrice(double price,int digits)
 {
  return(round(price/dblTickBase(digits))*dblTickBase(digits));
 }

double dblTickBase(int iCnt)
 {
  switch(iCnt)
   {
    case 5: return(1/100000);
    case 4: return(1/10000);
    case 3: return(1/1000);
    case 2: return(1/100);
    case 1: return(1/10);
   }
  return(1.0);
 }

I am reading an error of divide by zero

Any help is appreciated

1. Brian Lillard: I am reading an error of divide by zero

       case 5: return(1/100000);
   

   Of course it does.

2. Your 1/nnnn is equivalent to _Point.

3. double   normalize_price(double p, double d=0.0){
   double tickSize    = MarketInfo(_Symbol, MODE_TICKSIZE);    
      if(d > 0)   return round_up(p,      tickSize);
      if(d < 0)   return round_down(p,    tickSize);
                  return round_nearest(p, tickSize);
   }
   double   round_down(    double v, double to){   return to * MathFloor(v / to); }
   double   round_up(      double v, double to){   return to * MathCeil( v / to); }
   double   round_nearest( double v, double to){   return to * MathRound(v / to); }
