Yuki,
"Rounding" in Metastock database comes from the fact that all numbers
(including volume) in Metastock format are stored in 32 bit IEEE single precision
floating point format which resultion is limited to 7 significant digits.
So this is not really a downloader problem but rather Metastock format limitation.
AB keeps volume number in 32 bit integer field and hence it can store positive
numbers upto 2,147,483,648 with full precision (it can not however
store numbers higher than that, so either way there are advantages and disadvantages)
Best regards,
Tomasz Janeczko
