Using iStochasic again

[Ingvar Engelbrecht]

So I tried to figure it out.

This is my code in "OnInit()

--------------------

int stoM30;

MqlParam pars[5];

//+------------------------------------------------------------------+
//| Expert initialization function                                   |
//+------------------------------------------------------------------+
int OnInit()
  {
   string name=_Symbol;
   ENUM_TIMEFRAMES  period;
   ENUM_MA_METHOD   ma_method   = MODE_SMA;
   ENUM_STO_PRICE   price_field = STO_LOWHIGH;

   pars[0].type=TYPE_INT;
   pars[0].integer_value = 9;
   pars[1].type=TYPE_INT;
   pars[1].integer_value = 3;
   pars[2].type=TYPE_INT;
   pars[2].integer_value = 3;
   pars[3].type=TYPE_INT;
   pars[3].integer_value = ma_method;
   pars[4].type=TYPE_INT;
   pars[4].integer_value = price_field;
  
   period = PERIOD_M30;

   stoM30=IndicatorCreate(name,period,IND_STOCHASTIC,5,pars);

   if(stoM30==INVALID_HANDLE)
     {
      //--- tell about the failure and output the error code
      PrintFormat("Failed to create handle of the iStochastic indicator for the symbol %s/%s, error code %d",
                  name,
                  EnumToString(period),
                  GetLastError());
      Logger("OnInit", "Sto indicator fail");           
      //--- the indicator is stopped early, if the returned value is negative
      return(-1);
     }
  
   double buf[];
   CopyBuffer(stoM30,SIGNAL_LINE,1,2,buf);
  

   Logger("Testit","handle",IntegerToString(stoM30),DoubleToString(buf[0]),DoubleToString(buf[1]));

----------------------------------

Logger output;

2011-10-04-00-00    Testit_______    handle_______    10___________    0.00000000___    0.00000000___    _____________   

Obviopusly I am doing something wrong since I just get zeroes  in "buf"

OK found something out.

No data coming in when code below is in  "OnInit".

 So I moved the following code to CheckForOpen:

  CopyBuffer(stoM15,SIGNAL_LINE,1,2,buf);

  DStoM15 = buf[0];

 So now I got values in buf[0] and buf[1].

 But they dont change over time.  Do I really have to go all the way around and create and release the indicator when I want fresh values??
