Hi ,
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.
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:
do you want to promote it for free or your willing to pay for advertising?
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.
