Adaptive Price Envelope APE
See where price sits inside boundaries that adjust to completed-week direction and volatility, then check whether the wider evidence confirms the move.
Current completed-week read ยท 2026-08-28
Price is advancing above the adaptive centre
The envelope places current price in context without treating a single band touch as a signal. Direction, persistence and the evidence checks below determine the quality of the read.
Use the envelope for price location and Market Dynamics to see whether support beneath price is strengthening or weakening.

Model data
Through 2026-08-21
What Market Dynamics shows
Yes. Market Dynamics follows the completed-week transition between the two sides of a market cycle. Accumulation is the lower zone where selling pressure may be absorbed and support may be forming; distribution is the upper zone where earlier demand may be tiring and supply can begin to take control. The model measures both accumulation to distribution and the reverse journey, and waits for a deeper close or repeated closes before treating a new zone as confirmed. CPLE3 is 6% across its current move from distribution back toward accumulation. The journey remains open because neither the target nor a return to the source has been confirmed. For an investor, the value is in separating an apparent price move from a completed change in market character: target confirmation can strengthen the case that a new phase is taking hold, while a confirmed source return warns that the attempted change did not persist and the risk/reward should be reassessed. The completed journeys below show how 1 transitions in this ticker's stored history reached and confirmed the opposite zone.
