That's the trick. There's no way to know how many bars are on the
screen. The user can change the screen bar compression and totally
change the # of bars on the screen.
I look at the Highest/Lowest for some number of bars that I think
will be included in the onscreen chart, then aim the invisible
indicator line around that. If the Highest/Lowest lookback is too
short, the text might be below the top of the screen -- at least
until the old higher bars scroll off the screen.
It's messy either way.
