Lots of folks in the room are using constant tick charts.These
are charts where each bar or candle contains a set number of ticks or trades.
(One tick equals one trade.)
So a 133tick chart has 133 ticks (or trades) in each bar.
Advantages:
 Greater granularity than minute charts. Going from a oneminute to
a twominute chart (the smallest increment) can be like going from a
123 tick chart to a 255 tick. (Actual numbers vary widely.)
Tick charts provide the rough equivalent of fractional minute charts.
 Fewer really long bars during market surges, which many find hard
to look at.
 Often show much more useful displays for Globex sessions.
Disadvantages:
 Not all charting packages provide them.
