#property indicator_color1 clrGreen

#property indicator_color2 clrRed



extern int FastEMA=12;

extern int SlowEMA=26;

extern int SignalSMA=9;



input double bmi=25.;

double up[];

double down[];



int OnInit()

{  

   SetIndexBuffer(0,up);

   SetIndexStyle(0,DRAW_ARROW);

I am sure you are using this indicator from the expert's folder.

Move it to the indicator's folder then open it as an indicator not as an expert.

int OnCalculate(const int rates_total,
                const int prev_calculated,
                const datetime& time[],
                const double& open[],
                const double& high[],
                const double& low[],
                const double& close[],
                const long& tick_volume[],
                const long& volume[],
                const int& spread[])
  {

//skip ( default code )
   return(0);

  }

It speaks for itself.

The code that you have posted is an indicator so will not be executed as an expert.

Remove the file from your Experts folder and place it in the indicators file.
