Ken, I think you are asking whether you can add information to the Amibroker database that is not related to O,H,L,C,V, OI from a source that is different from Amiquote, right?
 
If so, I'm afraid that ASCII import is probably your best bet.  The way I've done that is to create a dummy ticker like QQQQa and then put information into the O array of QQQQa that relates to, say, bids and information into the H array of QQQQa for, say, asks.
 
Then, in order to operate on this information, one relatively straightforward way is to use the Foreign command, like Foreign ("QQQQa","O") when you need to retrieve bids.  Or you could have amibroker retrieve these fields on demand (in your code) using fopen commands from a .csv format.  or you could retrieve from .csv and put into static variables.  Or you could use the sql retrieval process made available by Amibroker.
 
Personally, I've done all four of these with success.  Each has their place.  But, before I go any further, perhaps you could confirm that this is what you are trying to accomplish....

Well, thanks, but I need to add many symbols read automatically from a spreadsheet file into the database. The Quote Editor will not do it automatically as far as I know.

Subject: [amibroker] Adding data to field in existing symbol database.

Amiquote and Import from ASQII are both aimed towards helping people import quotes from services like Yahoo.

No where that I can find does the Help file (or the Knowledgebase, or the Users Knowledgebase, nor past archived messages) talk about how to ADD a value to an existing field (say an empty volume or OI field) in an existing database.

Experimenting with the above mentioned tools does not produce the result I need.

I have nowhere else to turn as all of the above resources are silent.

As someone else said: "can someone toss me a bone" on this subject.

Thanks for any help.

Ken
