Self promotion is not allowed in the forums as such, but once you've been a member for 90 days, you can post a no-follow signature link. That way, if you participate in the forums, people will know about your site.
You can check out the forum rules for more details:
I am new to this forum and I like to promote my website...My web site is based on the stock trading tips...
can you suggest how to promote it ... please share your opinion.
You can find lots of discussions on promoting your website in the Internet Marketing section of the forum, and particularly in the "SEO FAQ" thread at the top of that page. Please have a read through that first, and then if you have any specific questions that haven't already been answered, feel free to post a new thread in that forum.
Any posts I write in Arial are on my mobile phone, so please excuse typos etc. Any posts I write in Verdana are on a PC, so feel free to berate me mercilessly for any mistakes
