Hello eveyone. First of all I have to say that I found a place to stay. You all are very kind and polite and always there to help us. I know that I am making so many questions,
but they are here because I really didn't find the answers to them still now. I really hope that, we your help, I can, finally, have them answered.
Thank you in advanced...


I'm new here and have searched the knowledge database but I could not figure out how could I do the following:

1 - I wanna create one database for each market ( and put everything for a specific country in it -> all historical quotes, intraday, news, fundamentasl, everything the
software give to us - I will be glad if you can contribute with "best practices" or any other better idea)
2 - Then I want to create a schedule to update each market separately, because each market closes in a different time
2.1 - In this case I would like to know how much time after each market closes, you recommend to download the data ?
2.2 - How can I automatically create a way to split the data when it happens, and if there is a way of correct dividends for all of data also
3 - I want to create a way of exporting each database created in step 1 and their information, to a correspondent Oracle databases (I dont know if the best way of
doing this is generating a CSV file the uploading it or if there is another option )
4 - I would like to know the differences between "Last download date" and "Last Symbol Data" options in the Download items
5 - I would like to know how can update all symbols and news create in step 1, and how often do I need to update historical database quotes
6 - I would like to know if its necessary to have your software running to do all this or if there is a way of doing it by command line for example so it it closes I still
can make everything work

I appreciate your help

thank you in advanced

regards

Gabriel

Did you ever get a solution to this? I would like to do the exact same thing except to SQL Server instead of Oracle

You have to export data in csv format then import the csv data into your SQL Server databases.

Thanks, that's what I'm doing. My issue is I'm using the script below which I found on the forum to export data and my US database crashes after about 5 years of data so I have to break the database into pieces. Is there a way to modify the script below to select certain dates (Ie, I can update monthly and just export the last month's worth of data)? I can then import that file into SQL. Thanks

From Forum: http://www.quantshare.com/title-95-export-to-csv-the-whole-database-including-symbols#axzz2EeTWX8VH

A whole copy of the database to a CSV file can be performed using the scripting language. Tools -> Script Editor.

Here is the script to perform this:

Symbol[] symbols = Symbols.GetSymbols();
System.Text.StringBuilder text = new System.Text.StringBuilder("");
for(int i=0;i < symbols.Length;i++)
{
Symbol sym = symbols[i];
HistoricalQuotes quotes = Quotes.GetHistoricalQuotes(sym.Name);
for(int j=0;j < quotes.Close.Length;j++)
{
text.AppendLine(sym.Name + ";" + quotes.Date[j].ToString("dd/MM/yyyy") + ";" + quotes.Close[j]+ ";" + quotes.Open[j] + ";" + quotes.High[j] + ";" + quotes.Low[j] + ";" + quotes.Volume[j]);
}
}

System.IO.File.WriteAllText(@"c:\quotes.csv", text.ToString());


- The last line reference the file.
- The format is: Symbol;Date;Close;Open;High;Low;Volume
