It will also start a new bar when the first real-time tick arrives,
whenever you load a chart, short-changing the last bar on the chart,
formed from historical data, to start that new bar, formed from
real-time data. The result is, you can't simulate real-time tick-bar
charting with TS from historical data.
IMO, it's correct to start a new bar at the beginning of a new
session; I just wish the charting was clever enough to do this when
loading historical data. After all, it has all the info it needs to
act this way.
Short-changing a bar in mid-session is simply a bug. The charting
should keep track of the tick count in the last historical bar, and
if we're within a session, add real-time ticks to it.
