Linking tools together in ATP is an efficient way to toggle and view securities across multiple tools such as Charts, Quote, News, Directed Trade/Depth of Book view, and Trade ArmorSM. Switch the symbol in one linked tool to automatically update the symbol in all linked tools. You can set up to five different color-coded toolsets. Double-clicking a security in your Positions, Watch Lists, Filters, or Ticker will automatically prefill that symbol into your default toolset (Gray). To link/unlink a tool, select the link icon located to the left of the symbol entry box.
