gbb483, they will not line up on the left, as this is the close from yesterday, so if any stock started the 2nd of January with a rise or a fall, they will start above or below the 0% line.
The right hand end of the line meets the percentage scale, to show the present move up or down.
The volume is to be ignored, this is only reference to the main stock on the chart (eg the header one, the one with the green line). Sadly on Big Charts you have to have something at the bottom, so its volume.
The charts now represent a whole 2 days of trading, so will resemble the light sabres until you get a few weeks of trading done. By the end of January they will start to be a little more like charts, and less like lines.
