Hello,

 

Check YAHOO WEB SITE FIRST before claiming anything is wrong:

For example:

http://finance.yahoo.com/q/hp?s=CELG

 

Now that's the contents of file downloaded by AmiQuote:

12-07-2007,60.00,60.25,59.08,59.65,3254200,59.65
11-07-2007,58.58,59.31,58.50,59.28,3305000,59.28

 

Now In AmiBroker:

 

 

The volume is correct 32023 HUNDREDS OF SHARES.

 

Note that since 4.90 AmiBroker by default imports data from Yahoo in HUNDREDS OF SHARES.

 

All numbers agree perfectly

 

If you want data imported in 1's shares (which is not recommended because of possible overflow

when you import wide market indices) you may edit aqh.format file (inside Formats folder) and replace

$VOLFACTOR 0.01

line with:

$VOLFACTOR 1

Subject: [amibroker] volume eod download from yahoo finance

version 4.90.5

the volumes downloaded from yahoo have been too low - from july 20th onwards , eg. today

NT trades 5.5 million, but the download shows 60,000 

CELG traded  4.3 million but the download shows 76,000

does anyone have a fix for this?

thanks for your help
