By request, I added some highly advanced, complicated new features. Now you can choose the text size, how many bars back from the last bar you want to position the text, and whether it's displayed above, at, or below the price!
Note: by positioning using time instead of bar index, it would be possible to move the text ahead (to the right of) the last bar, but I've found that this gets complicated because you have to account for the time frame of the graph, so I leave this as an exercise for someone else.
