Here's what I'd suggest you try:
When the first ticker is processed load all of the tickers of all of the
watchlist into a single string and then just search that string to see if
the ticker is in it. This way you only have to access the watchlist files
only once.
If (status("stocknum") == 0) // processing first ticker
{
watchlisttickers = categorygetsymbols(categorywatchlist,
CategoryFind("Watchlist A", categoryWatchlist));
watchlisttickers = watchlisttickers +
categorygetsymbols(categorywatchlist, CategoryFind("BuyMA",
categoryWatchlist));
watchlisttickers = watchlisttickers +
categorygetsymbols(categorywatchlist, CategoryFind("Congestion",
categoryWatchlist));
watchlisttickers = watchlisttickers +
categorygetsymbols(categorywatchlist, CategoryFind("Breakout_continueation",
categoryWatchlist));
}
yestprice=Ref(High,-1);
ChkWatchList = strFind(Name(), watchlisttickers);
Buy=(High>HHV(yestprice,180) AND Close<25) AND MA(V,20)>200000 AND
(ChkWatchlist==0);
//Buy=High>HHV(yestprice,180) ;
Filter=Buy;
Watch out for line breaks in the above.
I have not tested this but in theory it should work.
