The opening range — the price structure formed in the first minutes of the RTH session — often defines the directional bias for the rest of the morning. ORBFlow monitors how price interacts with those boundaries and highlights potential directional conditions, classifying initial breakout contact as PRIME and subsequent re-emergence conditions as MINOR. Eastern Time anchoring ensures session consistency regardless of the trader's local timezone.

Training Tip
Watch the PRIME/MINOR classification carefully — a PRIME condition on high relative volume during the first breakout attempt is qualitatively different from a MINOR re-emergence later in the session. Use the strength meter and ADX filter together to assess whether the breakout has structural backing before treating it as actionable context.
