J2WS's shared trades:

You can write your trade notes and comments using markdown syntax for links, images, etc. Some quick examples to get you started:

• link: either just type the url, like https://www.tradervue.com
  
  Or, use this: [my link](http://www.thelink.com)
  
  
• images: 
  
  
• headers: use #, ##, ###, ####, or #####. For example,
  
  ### This is a header

For other options, see Markdown syntax documentation.

Note that normal HTML tags are not supported in Tradervue.
