Time-Based TFlow (TTFlow)
The Time-Based TFlow chart displays bars built based on Time & Sales data similar to regular
time bars, but with the addition of bid and ask volume. Bid and ask volume is available intraday
only. This chart also provides access to historical data.
Time-based bars appear as TFlow bars with open and close markers.
The bid volume is represented by the red part of the bar, and the ask volume is green. The
color brightness and the width of Time-Based TFlow bars are based on the current bar’s volume
relative to the volume history. The preferences offer four preset colors/widths. The higher the
volume then the brighter and wider the bars.
Three techniques are available in the preferences to determine the current bar’s volume relative
to the volume history: percent ranking, percent of average, and actual. These values are
explained in parameters.
This chart can be used with the same contracts and studies that you can use with a regular
time bar. You cannot use pre-trade analytics or volume studies. Volume information will not be
displayed if time and sales trade volume is unavailable.
