-Added total number of price legs in the display table (from start time; from which averages are derived). Visual legs/boxes painting on chart are limited to 500, but the actual number of legs processed by the script can be much larger than this. I wanted to clear up any possible confusion, as well as giving the user an idea of the dataset size.
-Added option to toggle on/off the visual vertical start time marker, as well as color/thickness options. Occasionally the script can glitch in realtime and this line briefly flips horizontal =>> option to turn off this visual aid if it annoys. User input start time would be unaffected.
