What it measures

ZoneDecoder AI builds its zones from live volume and order flow. It looks at tick data, volume and the way trade is distributed across prices, and marks the areas where it expects a reaction.

  • Zone: a shaded box between a low price and a high price. A zone that is still active extends to the right of the latest bar, so you can see it ahead of price.
  • Confidence: a score the indicator gives each zone. It ranks how strongly the zone stands out. It is not a win rate.
  • Stronger look: zones with a higher confidence are drawn with a stronger fill and a thicker border.
  • Balanced zones: zones the indicator reads as balanced have a dashed border.

How traders read it

  • Zones above price: possible resistance. Traders look for a reaction, a rejection or a break, and plan targets and scale-outs around them.
  • Zones below price: possible support, used the same way.
  • Higher confidence: the indicator rates the zone as stronger. Compare zones with each other, not with a win rate.
  • Price inside a zone: the market is at a level where the indicator expects a reaction. Wait for the reaction before you act.

Tip. Pair the zones with the Volume Profile. A zone that sits near a point of control or a value area edge has two reasons to matter.
