01
Bullish and bearish zones with independent styling, opacity and extension.
INDICATOR
Most flips are noise. This one refuses to draw them.
TA Zones
The aggression tools tell you who was initiating. TA Zones takes the moment that reading actually changed hands and projects it forward as a zone on the price panel — so the level is on the chart before price returns to it, not explained afterwards.
Specification
Panel
Price panel overlay. Draws on any bar type.
Source
The same tick classification the True Aggression and Aggression ROC histograms use. Set the thresholds to match them and the three agree by construction.
Zone origin
Full bar, body, mid-half or a padded range — your choice.
Extension
Infinite, a fixed number of bars, until filled, or until the opposite side flips.
Calculation
On bar close, with a hidden 1-tick series added to the chart.
Built on refusal
Four conditions, and all four have to agree.
A zone appears only when the aggression threshold is crossed, the rate of change confirms the momentum behind it, price structurally reclaims or loses the level, and the bar closes on the right side of it. A flip that fails any one of those — absorption, a wick, a single aggressive print into a resting wall — creates nothing at all. The empty chart is the feature. Most zone indicators draw on every flip and leave you to filter them; this one does the filtering and draws far less.
02
Flip markers at the bar where initiative changed, separate from the zone itself.
03
Thresholds shared with the True Aggression and ROC histograms, so the three read as one system.

Positioning
Where it fits.
The visual end of the aggression pipeline. True Aggression tells you who is initiating, ROC tells you when that is accelerating, and Zones puts the level on the chart so you are looking at a price rather than a histogram.
