SRE (WhaleQuant Structural Regime Engine) SRE evaluates how price structure evolves across daily and weekly timeframes to define the prevailing market regime. Beyond identifying trends, consolidations, and exhaustion phases, it distinguishes between raw structural strength and deployable participation quality. The model dynamically adjusts for structural context and extension risk, assessing whether conditions are supportive, stretched, fragile, or structurally impaired. Its purpose is not to forecast precise price levels, but to determine whether risk deployment is aligned with underlying market structure.

This reading is based on the last 20 trading days of 15-minute price, volume, and VWAP data. Price is trading 3.1% above the recent estimated cost basis of 9.03, which keeps the recent cost structure in a clearly stronger position. Price is above the main cost band (8.97 to 9.11), and about 86% of recent positioning is already in profit. That supports trend strength, but it also raises the chance of profit-taking if momentum cools. The next lower support area sits around 9.17 to 9.23. It looks more like a first buffer than a major floor. From a trading point of view, the trend still has support. The main question is whether deeper pullbacks can still hold the next lower 9.17 to 9.23 support zone.
