[amibroker] Help with Barcount

["prog200" <prog200@xxxxxxxxx>]

Found this code in early Emails and tried it out but not getting any
buy signal at present only old ones and not most of them are not
showing up. 

I ran it on BA and the last signal was in 12/2000 but nothing after that.

What gives?

Buy = Cross( MACD(), Signal() );
priceatbuy=0;
 
 for( i = 0; i < BarCount; i++ )
{
      if( priceatbuy == 0 && Buy[ i ] ) 
      priceatbuy = BuyPrice[ i ];
      t1 = i;
 
     if( priceatbuy > 0 && SellPrice[ i ] > 1.1 * priceatbuy )
      {
        Sell[ i ] = 1;
       SellPrice[ i ] = 1.1 * priceatbuy;
        priceatbuy = 0;
     }
      else
        Sell[ i ] = 0;
 }

Filter = C > 2;
Buy  = ExRem(Buy,Sell);
Sell = ExRem(Sell,Buy);


Thanks 
Marty
