Hi
ICICIDirect's website is slow specially due to overwhelming number of customers ( they captured 68% of on-line trading market). I wrote few mails to ICICI to enhance their servers capacity, but in vein.
For intraday, ICICI is NOT Good, they dont provide traders terminal for fast transaction and tracking - Kotak & sharekhan provides. ICICI good for broad ranges of products like they have highest number of MFs, Postal Schemes and many. Their brokerage is also highest, so in high volume, ICICI is not paying.
If you face problem in openning ICICI site, I would recommend dont use Internet Exploerer - use Netscape 8 or Opera browser.
