Speed of tape

How fast the tape is moving, read two ways: a row for every bar, and a histogram by price inside a box you draw.

Setting names are shown in English because that is how they appear in the Quantower settings window.

Two readings, two questions

"Fast" only means something against a reference, and the useful reference changes with the question.

The grid row — bar by bar

A row in the per-bar statistics grid, one bar per chart bar, on by default. It is a small histogram rather than a number. Bar height is the measurement you pick — average trade size by default, or trades, volume or delta per second — and the colour is the direction of that bar's delta. In the default bipolar style, bars with positive delta stand above a centre line and bars with negative delta hang below it.

The speed profile — price by price

Inside a range profile box, Range profile: tape histogram adds a second histogram along the box's right edge. Each row is how quickly that price was passed through: what traded there, divided by the time price spent there. It is off by default, and the T/s chip under a selected box switches it for that box alone.

Rows that are both thin on volume and quick get a bright outline (Range profile: fast LVN highlight) — the places price went through rather than traded at.

Honest limits

• The speed profile is off until you ask for it. The T/s chip under a selected box switches it for that box.
• The tape speed tools are Pro. They sit alongside the per-bar statistics grid and the range profile.
• They describe; they do not predict. Speed is a measurement of what has already traded.
