[amibroker] need help in optimizing

["murthysuresh" <money@xxxxxxxxxxxxxx>]

The following script takes 20 minutes to execute when i set the scan 
to last 1 day only. When i broke down the factors into multiple 
pieces,
i found that the following line adds 15 minutes to the scan times.  
how can i optimize it so it runs faster

ChkWatchlist=InWatchList(CategoryFind("Watchlist A", 
categoryWatchlist )) OR InWatchList(CategoryFind("BuyMA", 
categoryWatchlist )) OR  InWatchList(CategoryFind("Congestion", 
categoryWatchlist )) OR  InWatchList(CategoryFind
("Breakout_continueation", categoryWatchlist ));




-- The actual script that i ran.

yestprice=Ref(High,-1);
ChkWatchlist=InWatchList(CategoryFind("Watchlist A", 
categoryWatchlist )) OR InWatchList(CategoryFind("BuyMA", 
categoryWatchlist )) OR  InWatchList(CategoryFind("Congestion", 
categoryWatchlist )) OR  InWatchList(CategoryFind
("Breakout_continueation", categoryWatchlist ));
Buy=(High>HHV(yestprice,180) AND Close<25) AND MA(V,20)>200000  AND 
(ChkWatchlist==0);
//Buy=High>HHV(yestprice,180) ;
Filter=Buy;

Thanks seede
