Re: [amibroker] Re: Esignal EOD db update?

Hello,

Data should be saved if everything is set up properly.
Assuming that you have "local data storage" set to enabled,
the only reason could be some problem with data saving.
You may need to check if you don't have "READ ONLY" flag
set on files inside database. Such things happen if database
is restored from CD-ROM for example.

Also if you used ASCII importer (instead of entering symbols
manually or using "Import watchlist") all symbols added by the importer
have "Use local database only for this symbol" and they are EXCLUDED from real-time update

This is described in the User's Guide:
http://www.amibroker.com/guide/h_rtsource.html

Go to Symbol->Information and verify for each symbol that you have trouble with.
If  "Use local database only for this symbol" is checked it means that
it is EXCLUDED from real-time update (via eSignal).

You would need to UNCHECK this box for every symbol.

This can also be done automatically by running this scan:

AB = CreateObject("Broker.Application"); 
st = AB.Stocks(Name()); 
st.DataSource = 0;

Tomasz Janeczko
