Hi, just wanted to let you all know that we are still using Rumbletalk. You can always let me know if you need anything. I will be happy to assist you! I wanted to show you a demo chat  so you can all see how it looks like.

Hey guys!

Thanks a lot for answers!

I did some research in last days and this is what I came up with. I tried your suggestion as well.

I had several points which are important to me.

1 - First I needed a chat that can be seen in mobile (all versions) so I narrowed down the search for html5 chat room that look good on both mobile and pc.

2 - I needed a custom design, I needed my background to be black or transparent. This was very hard to find (my site is dark).

3 - I do not like to install the chat in my server as this is high cpu and resource consumer. So I need a chat service.

4 - Lastly, I needed the ability to add youtube videos and upload files (technical analysis).

I have checked several chats and only 2 met my needs, RumbleTalk and Cbox.
I choose RumbleTalk finally as it can be integrated into my page and not only as toolbar.

Maybe a bit off topic but I would like to hear out your recommendations.

I am looking for a chat service to use on my algo-trading website. It needs to have option for adding youtube videos and posting charts and also I want to be able to edit design a bit.

I came across Rumbletalk and Envolv but I am still finding more options.

Which one you recommend?
