First copy the url of the ticker. not the html or any of the other things. You need to copy the url. Then you go to edit your signature and click on the landscape icon (it has a mountain on it i think) It will be up by where you can change the font and everything. After that all you do is post your url. Make sure that you don't put two https:// things cause that happened to me and it wouldn't work.
Or create your ticker, then when it gives you an option of which codes to get chose UBBcode/BBcode & copy and paste it into your signature
