ICUSTOM : get the right data

Hi!

and thanks in advance for everyone who's givin' up his time supportin' the community.

I got the Supertrend-Indicator

https://www.mql5.com/en/code/576

i'm not good at programming with MQL5 so if i'm wrong approach, could you give a simple example?

The strategy is simple, I want to open only buy positions when the trend is positive, and only sell positions when it is negative.

  SuperTrendHandle=iCustom(NULL,0,"supertrend",10,3,false);

  return(INIT_SUCCEEDED);

  ArraySetAsSeries(Supertrend,true);

  CopyBuffer(SuperTrendHandle,3,0,1,Supertrend);

  double SUPERTRENMIO = Supertrend1[0];

  Comment(Supertrend[0]); // i used this to try to see which type of value i got.

   SetIndexBuffer(0,Filled_a,INDICATOR_DATA);

   SetIndexBuffer(1,Filled_b,INDICATOR_DATA);

   SetIndexBuffer(2,SuperTrend,INDICATOR_DATA);

   SetIndexBuffer(3,ColorBuffer,INDICATOR_COLOR_INDEX);

   SetIndexBuffer(4,Atr,INDICATOR_CALCULATIONS);

   SetIndexBuffer(5,Up,INDICATOR_CALCULATIONS);

   SetIndexBuffer(6,Down,INDICATOR_CALCULATIONS);

   SetIndexBuffer(7,Middle,INDICATOR_CALCULATIONS);

   SetIndexBuffer(8,trend,INDICATOR_CALCULATIONS);
