How call buffer value from supertrend_nrp_new_mtf_2 indicator

New comment
 

I need help for buffer value calling.

I hope this forum help me.

here is its buffers

int init()
{
   IndicatorBuffers(6);
      SetIndexBuffer(0, Trend);    SetIndexLabel(0,"SuperTrend");
      SetIndexBuffer(1, TrendDoA); SetIndexLabel(1,"aaaaa");
      SetIndexBuffer(2, TrendDoB); SetIndexLabel(2,"bbbb");
      SetIndexBuffer(3, Direction);
      SetIndexBuffer(4, Up);
      SetIndexBuffer(5, Dn);
         period    = MathMax(1,period);
         TimeFrame = MathMax(TimeFrame,+_Period);
   IndicatorShortName("SuperTrend");
   return(0);
}

I call  0  and get buy value 

But can never call sell value .

I check data window also.

when point on green line it show value on supertrend

when point on red line it show values on both supertrend and aaaaa .

So call this two value for sell value ,not work

here is my buy value

double buyy=iCustom(NULL,0,"supertrend_nrp_new_mtf_2",period,multiplier,0,i) ;

here is indicator codes

I only need effective help.

 
  1. Aung Swar: I need help for buffer value calling. 

    double buyy=iCustom(NULL,0,"supertrend_nrp_new_mtf_2",period,multiplier,0,i) ;

    Help you with what?

              Be precise and informative about your problem

    You are looking at buffer zero (Trend[]) and defaulting all inputs except period. Only you know what you want.

          SetIndexBuffer(0, Trend);    SetIndexLabel(0,"SuperTrend");
      SetIndexBuffer(1, TrendDoA); SetIndexLabel(1,"aaaaa");
      SetIndexBuffer(2, TrendDoB); SetIndexLabel(2,"bbbb");
      SetIndexBuffer(3, Direction);
      SetIndexBuffer(4, Up);
      SetIndexBuffer(5, Dn);

  2. Be careful with NULL.

    1. On MT4, you can use NULL in place of _Symbol only in those calls that the documentation specially says you can. iHigh does, iCustom does, MarketInfo does not, OrderSend does not.
    2. Don't use NULL (except for pointers where you explicitly check for it.) Use _Symbol and _Period, that is minimalist as possible and more efficient.
    3. Zero is the same as PERIOD_CURRENT which means _Period. Don't hard code numbers.
    4. MT4: No need for a function call with iHigh(NULL,0,s) just use the predefined arrays, i.e. High[].
