Wyckoff Method Analysis
A market-structure read based purely on real price and volume data — not full classic Wyckoff schematic identification (Phase A-E), but a quantitative analysis of what can reliably be computed: trading ranges, "effort vs. result", volume within the range, and Spring/Upthrust detection.
The stock is in a clear uptrend with no defined trading range in the period examined.
Low confidence
Evidence Behind This Read
- 🟢Rising price trend — A 10.4% change over the last 50 days, with no defined trading range.
- 🔴Divergence between price and cumulative money flow (A/D Line) — Price and the cumulative Accumulation/Distribution Line are moving in opposite directions — a classic Wyckoff sign that the move isn't backed by real money, and may be less stable than it looks.
- 🔴Bar with buying-climax characteristics — On 2026-07-16: volume 2.2x the average and a spread 1.6x wider, with a close suggesting counter-absorption.
The Wyckoff Method, developed by Richard Wyckoff in the early 20th century, reads the balance of supply and demand through price and volume, based on the premise that large investors ("smart money") quietly accumulate shares before rallies and quietly distribute them before declines. The read here is based solely on real price and volume data — full, precise identification of classic Wyckoff patterns (such as Phases A-E) requires human chart-reading experience and judgment, so this is an approximate algorithmic read, not a substitute for professional analysis. This should not be considered investment advice.
🎯 Trade Planning (M.A.E.E Framework)
Based on a mechanical trading method: market structure → value zone → ATR-based exit point. Not investment advice — a calculation tool only.
1️⃣ Market Structure
🟢 Uptrend
The price is above the 200-day average — per the market-structure method, this environment mainly favors looking for buying (Long) opportunities.
2️⃣ Value Zone
🟡 Price far from value zone
The price is currently far from the 50-day average — the method recommends waiting for a "pullback" before entering, rather than chasing prices.
3️⃣ Suggested Exit Point (ATR-based)
Method formula: Stop-loss = support minusone ATR margin — this way the stop adapts to the stock's actual volatility, rather than an arbitrary number.
