Herman,
Stewart asked at
http://groups.yahoo.com/group/amibroker/message/38506
something simple : how to select the top5 of an exploration. Any idea
for this request ?
[If I understood well, to run an exploration
Filter=1;
AddColumn(MACD(),"MACD");
for 100 stocks and see in the result list ONLY the top5 MACDs,
nothing else]
I do not see how can I do it.
[I hope to avoid MAX(Foreign("~AAPL-MACD","C"),MAX(Foreign("~ABGX-
MACD","C"),...]
Any idea appreciated.
