MQE - Market Quality Engine v1.6
# MQE — Market Quality Engine v1.6
**MQE is not a buy/sell signal generator.** It is a Decision Support System that measures the quality of the current market environment on a standardized 0-100 scale. Its purpose is not to dictate "Buy" or "Sell," but to present, transparently and explainably, how favorable current market conditions are for opening a directional position.
## Methodology
MQE combines evidence from five independent analytical engines:
- **Trend Engine** — Evaluates market structure direction using EMA structure, AlphaTrend, and Comparative Relative Strength (CRS) against a benchmark (default BIST:XU100).
- **Flow Engine** — Measures directional capital commitment using a Cumulative Delta Volume (CDV) approximation; unlike raw volume, it prioritizes directional information over mere activity. The engine's highest-weighted criterion (40%) is whether CDV's fast average (EMA5) remains above its slow average (SMA68) — a strong, sustained CDV reading is interpreted as confirmation that the underlying scenario has not broken down.
- **Opportunity Conditions Engine** — Built around Relative ATR, this engine evaluates "tradability" rather than raw volatility; neither extreme compression nor extreme expansion is treated as inherently favorable.
- **Participation Engine** — Uses Relative Volume to assess whether sufficient market participation supports the current move; it is non-directional and primarily feeds into the Confidence output.
- **Momentum Engine** — MFI-based; deliberately avoids classic overbought/oversold interpretation and instead evaluates the persistence of directional energy as a supporting, confirmatory layer.
The output of these five engines is combined using regime-adaptive weighting — based on the current market **Regime** (Bull Trend / Bear Trend / Range / Transition) — into independent **Long Score** and **Short Score** values (0-100). Contradictions between engines are captured separately by a **Penalty** mechanism that only ever reduces the score, while the internal consistency of the evidence is reported through a fully independent **Confidence** value (0-100) that never alters the score itself. A high score paired with low confidence signals an environment that looks attractive but is backed by inconsistent evidence; high score with high confidence signals strong agreement across all evidence families.
For quick manual screening, MQE also provides a composite **Grade** (A+ through D), calculated separately for both directions.
## Dashboard
Two independent panels are provided: a **Primary Dashboard** (Long/Short Score, Confidence, Regime, and per-engine summaries — shown side-by-side for both the last closed bar and the live bar), and a **Diagnostics Panel** (per-engine breakdowns, penalty sources, raw indicator values, and active confirmation timeframes).
## Timeframe Adaptivity
Higher-timeframe confirmation and the AlphaTrend calculation automatically scale to the chart's timeframe (from 5-minute up to weekly), so no manual configuration is required by default; manual overrides remain available for advanced customization.
## Credit
The AlphaTrend calculation logic is adapted from the publicly known AlphaTrend concept originally developed by Kıvanç Özbilgiç.
## Disclaimer
MQE is not financial advice; it provides a statistical assessment of market conditions only. Past performance or evidence consistency does not guarantee future price behavior. All trading decisions and risk management remain the sole responsibility of the user.
