Hi Yuki,
konichiua? I guess this is not the right why to say hi, but anyway ..
do you know where I can get a list of Japanese stocks symbols?
There are more than 2000 on IB, and it would take too much time to
copy and paste into excel since it alloows to have just a limited
number per page.
With other exchanges yahoo has the index components, so you just go
there and copy into excel but not for Japan (at least not the english
versio of yahoo finance, may be you can help me with the japanese one.)
Msn has the EOD data
(do u know how reliable) but no index components either ..
Do you where to find list of stocks sorted by market capitalization?
Thanks
Ly
