Candlesitck above averege

Heey. This forum is GREAT!!!! Tanks Brothers!
I'm new to MQL, and I'm a big doubt.
the code below inserts a market order if the sale price and the purchase is above or below the average.
I would like to know how to make a candle is above or below average send the order. 

 Sorry if there are gross errors of English!

MA=iMA(NULL,0,MA,0,MODE_EMA,PRICE_CLOSE,0);

  if(OrdersTotal()<4)
     {

      if(Bid<MA)
        {;
         OrderSend(Symbol(),OP_SELL,Lots,Bid,10,0,0);
         CurrentOrder++;
           } else if(Ask>MA){
         OrderSend(Symbol(),OP_BUY,Lots,Ask,10,0,0);
         //CurrentOrder++;
        }
