JD, by default the Yearly RoC indicator will always return the current
YTD RoC %. If you change the exploration date to a specific past
date, then it will return that year's YTD RoC %.
This can be changed in the user-input section, to display only one
specific year if needed.
Plot the indicator below any chart, and it will answer all your
questions.
