Doubt with iCustom

Hi, 

I am a new member in this web. I am learning to programm on mql4. First i create two indicators:

- create arrows with values of fractal down

- create arrows with values of fractal up.

Now, i want connect this two indicator with other indicator wit the function "icustom".

I have this for learning to programm, this indicators not use for trade.

The problem is that my last indicator give me arrows in every candles:

My two indicators that give me fractals arrows are:

1-fractalsUp

2-fractalsDown.

The extern setting in this two indicators are:

-Equals

-nLeftUp

-nRightUp

-nLeftDown

-nRightDown.

and mi code of the las indicator is:

for (int i=0;i<limit;i++)

fractalsDown[i]=iCustom(NULL,0,"fractalsDown",Equals,nLeftUp,nRightUp,nLeftDown,nRightDown,1,i);
}
return(0);
} 
   

 I would like that you help me to learn to programm. 

Thank you very much.
