I've been spending some time going through charts and with the aid of the Fib Retracements tool, (using the 0% and 100% lines only) marking historical entries and exits (a process that can't be done automatically).

It would be extremely helpful to have an additional element on this Fib tool which gives the difference (hence the appalling pun in the title!) between the 0% and 100% levels. So if 0% = 2500 and 100% = 2526, the difference, '26' would be immediately visible.

I'm probably asking for the impossible but is this something that's achievable without very advanced coding?

Thanks for letting me know.
