Maybe you can help others to help you by actually giving some details.

Do you go to the doctor and just say "I'm ill, please cure me"? No, you tell the doctor your symptoms so that he knows where to start diagnosis.

  1. "Doesn't work" is meaningless — just like saying the car doesn't work. Doesn't start, won't go in gear, no electrical, missing the key, flat tires — meaningless.
  2. Your problem is your code doesn't even compile. 
          slowerMAafter=iMA(NULL, 0, SlowerMA, 0, SlowerMode, PRICE_OPEN, i-1);
       int whichCross = iMA-1;
       if (iMA[whichCross][=High] >=alertsLevel) || iMA[whichCross][=Low] >= alertsLevel)
    You have code that correctly calls the iMA function. Then you use it as a variable (wrong) and then you use it as an array (wrong).
