class=528544115-30072003>Oliver,
FWIW
the way I do it is with 2 databases. One retrieves RT day bars and the second
retrieves 1 minute bars. The EOD database can have 10 years of data but the last
bar is "Live". You may wish to establish a historical DB with Yahoo/MSN or the
data vendor of your choice (I use QP2) then simply switch your EOD DB to esignal
to see the day progress in RT
Regards,
Jayson

(unknown) : MyTrack / Esignal
datafeedHello,Thanks for the answer regarding
the ref function.For the datafeed I understand that if I use MyTrack I
will have to handle 2 seperate databases as suggested on the website. But
for Esignal feed it is not stated on the website that 2 seperate
databases are necessary. Will I have only one database including
realtime and EOD data if I use
Esignal?Thanks,Olivier--- In amibroker@xxxxxxxxxxxxxxx,
