ankityadav: need a horizontal lines when ever the two line crosses each other a
     if(fastsma>=slowsma)
You check for fast above or below slow, not a cross of fast and slow
    double fastsma=iBands(NULL,0,InpFastSMA,Inpdev,0,PRICE_CLOSE,MODE_SMA,limit);
    double slowsma =iBands(NULL,0,InpSlowSMA,Inpdev,0,PRICE_CLOSE,MODE_SMA,limit);
    ExtBuffer1[limit]=fastsma;
    ExtBuffer2[limit]=slowsma;
     if(fastsma>=slowsma)
You want a line when they cross.
    double fastsma=iBands(NULL,0,InpFastSMA,Inpdev,0,PRICE_CLOSE,MODE_SMA,limit); 
    double slowsma =iBands(NULL,0,InpSlowSMA,Inpdev,0,PRICE_CLOSE,MODE_SMA,limit);
    ExtBuffer1[limit]=fastsma;                                                    
    ExtBuffer2[limit]=slowsma;                                                    

    double fastPre=iBands(NULL,0,InpFastSMA,Inpdev,0,PRICE_CLOSE,MODE_SMA,limit+1),
           slowPre=iBands(NULL,0,InpSlowSMA,Inpdev,0,PRICE_CLOSE,MODE_SMA,limit+1);
    bool wasAbove = fastPre > slowPre,
          isAbove = fastsma > slowsma,
         isCross = wasAbove != isAbove;
  if(isCross){                 test for a cross
     if(fastsma>=slowsma)                                                         
      :
//   else if(fastsma<=slowsma) unnecessary test removed
     else
      :
  }
