I was trying to search an option which will export the data from AmiBroker to a folder where the data will be stored in seperate csv sheets. Here is a simple trick to export your Amibroker EOD Database to CSV Format. For eg. Nifty will be stored in a sheet where the data will be there from the date specified in the Automatic Analysis window to the date specified in Automatic Analysis window
AFL Code for Exporting to CSV
Steps to Backup your Data
1)Save the Export to CSV AFL Code to C:\\Program Files\\AmiBroker\\Formulas\\Custom path
2)Create a Folder Name “Amibackup” in C:\\ Drive
3)Open Amibroker ->Analysis-> Automatic Analysis
4)Select All Symbols option from the Apply to coloumn and All Quotatios from the Range Column
you can also select specific Stocks by selecting the suitable options from the Apply to Column
5)Run SCAN
6)Amibroker Database converts to individual .csv file
Download Export CSV data from Amibroker AFL code
Here the limitation is that you cannot specifiy the range of Date. By Default it will download from starting date to
ending date

February 12, 2010 at 8:43 pmGreat code
thank you
I cud backup my ami data
Govindharaj says
January 2, 2011 at 11:19 pmHi.. Thanks for the code.. Assume that My hard disk’s C drive crashed due to virus and I can’t able to retrieve any past datas.. So, I’ll format the disk and will create a new database which will accept only .txt format..
My question is,Is it possible to create Ami database which will accept both .csv and .txt format..? Since, our backup is in .csv format I raised this Question..
Thank you..
Rajandran R says
January 2, 2011 at 11:35 pmYeh Govindharaj… It supports both .txt and .csv format… you just simply edit the afl code and change it to ur required format and get the backup….
Now use import wizard and import ascii funtionality to import those backup data into ur new amidatabase
Govindharaj says
January 2, 2011 at 11:33 pmHi.. I just replaced .csv with .txt in the first line of the code and got backup in .txt format.. Sorry for the previous post..
But, how to use these datas in a new Database..?
Thank you..

April 30, 2012 at 7:29 amyes it can used for IEOD you need to edit the code according to your required output format. Small knowledge of C/C++ is good enough to edit the code

While i am trying to take backup the database in amibroker using the above afl it shows an syntax error as below..
fh = fopen( “

Error 31.
Syntax error, unexpected $end, expecting ‘)’ or ‘,’
Kindly help in this regard.

Copy the AFL code from here directly to your notepad and from notepad then copy to your amibroker code editor. Direct copying from
website sometimes creates Double quotation problem.
Rajandran R says
December 7, 2014 at 11:50 amYeh spot out the problem. Now it is corrected.

November 11, 2013 at 12:37 amhi
still the same syntax error apears
i had already done copy to note pad and then copy to farmula
still not working any solution to save data in amibroker ????
geet says
February 12, 2014 at 10:35 pmsolved the problem of syntax error..
the inverted commas should be replaced
for example -- fh = fopen( “c:AmiBackup”+Name()+”.csv”, “w”);
to
fh = fopen(“C:AmiBackup”+Name()+”.csv”, “w”);
this will solve the problem. although you will have to change all the commas in the code.. not just in this line

January 28, 2018 at 12:05 pmNice utility. One query where does it store the csv file?

February 23, 2018 at 9:03 pmHi Rajendran,
I am having a bit of a problem with this code. Firstly, I was trying to export intraday data. So I removed the comments to include time. I am afraid the data is coming in one continuous line and there are no line breaks. The time is also not coming correctly they are all coming as 00:00:00.
When I see the data in the quote editor and of course in Ami the data is displayed correctly as bars.
My final code is pasted below for ready reference.
Please help…
TIA
Praveen.
Code===========================
fh = fopen( “c://AmiBackup//”+Name()+”.csv”, “w”);
if( fh )
{
fputs( “Ticker,Date,Open,High,Low,Close,Volume”, fh );
y = Year();
m = Month();
d = Day();
r = Hour();
e = Minute();
n = Second();
for( i = 0; i < BarCount; i++ )
{
fputs( Name() + "," , fh );
ds = StrFormat("%02.0f-%02.0f-%02.0f,",y[ i ], m[ i ], d[ i ] );
fputs( ds, fh );
ts = StrFormat("%02.0f:%02.0f:%02.0f,",
r[ i ],e[ i ],n[ i ] );
fputs( ts, fh );
qs = StrFormat("%.4f,%.4f,%.4f,%.4f,%.0f",O[ i ],H[ i ],L[ i ],C[ i ],V[ i ] );
fputs( qs, fh );
}
fclose( fh );

February 24, 2018 at 12:12 amThanx Rajendran,
I figured out the issue… Guess, the line feeds are missing.. Thats the reason for the data coming continuous.
As regards the time stamp issue, it needs to be set in the settings to one minute and then it comes out just fine.
Posting it here so that others may also benefit…
HIH,
Praveen.
