Operational Integrity,
Verifiable by Design

Arkenwell is a quantitative analytics terminal for NIFTY & BANKNIFTY options traders. Every metric we display — Gamma Exposure, Delta Exposure, dealer positioning, volatility surface — is computed directly from NSE exchange data, using documented methods, on versioned engines. This page is where we show exactly how, and where our models are limited.

01
Dealer Positioning (GEX & DEX)
Proprietary Gamma and Delta Exposure models for precise market regime detection and institutional hedging analysis.
02
Volatility Surface Analytics
Real-time SVI-calibrated Implied Volatility tracking smile, term structure, and 25-delta skew dynamics.
03
Deterministic AI Contract
Our NLP engines are strictly bound by a read-only data contract with our quant pipelines. Zero hallucination.
04
Exchange Data Fidelity
Institutional-grade direct NSE options feeds. Missing values are explicitly flagged, never filled with synthetic estimates.
01 · Our Commitment

“Arkenwell is not designed to predict markets. Arkenwell is designed to reveal market structure — and to show its work.”

Financial media narrates price moves after they happen. We focus on the mechanics that precede them — dealer gamma balances, delta-flow regimes, liquidity walls, and volatility term structure — and we document how every figure is derived, so you never have to take a number on faith.

01
Mathematics Before Narratives
Greeks, delta balances, and dealer hedging flows are computed from raw exchange data — never reverse-engineered from price action.
02
Probability Before Certainty
Markets are distributions. We surface IV surfaces, strike-level risk boundaries, and probability tools — not fake directional calls.
03
Structure Before Opinion
Open-interest clusters, gamma-flip levels, and liquidity walls give durable context that survives sentiment shifts.
04
Transparency Before Marketing
Model assumptions, data limitations, and pipeline architecture are documented openly on this very page.
02 · Data Provenance

Every Number Traces Back to the Exchange

Arkenwell's analytics are built on a tiered data architecture. NSE exchange data is the ground truth; institutional streaming feeds provide redundancy and cross-validation; our own engines compute derived metrics on top — and nothing is invented in between.

ZERO-FABRICATION POLICY

Arkenwell does not fabricate market data, dealer-positioning estimates, historical records, or AI-generated metrics.

When underlying exchange data is unavailable, insufficient, or delayed, the platform states this explicitly on the affected panel — it never substitutes synthetic or interpolated values without disclosure.

Unavailable → labelled, not filledInsufficient History → labelled, not filledDelayed → labelled, not filled
PRIMARY TIER
NSE Exchange Ground Truth
NSE Option Chain — NIFTY
Full strike ladder: open interest, volume, IV, bid/ask, Greeks — refreshed each market cycle.
NSE Option Chain — BANKNIFTY
Complete derivatives feed across all active BANKNIFTY expiries.
NSE Derivatives OI
Strike-level open interest for all expiries — the primary input to GEX/DEX computation.
NSE Market Data
Underlying spot and futures prices for delta-adjusted exposure calculations.
SECONDARY TIER
Redundant Institutional Feeds
Institutional WebSocket Stream
Professional-grade streaming — real-time tick, option chain, OHLCV, and derivatives OI with sub-second latency.
Redundant Derivatives API
Independent pipeline for NIFTY & BANKNIFTY option-chain redundancy and cross-validation.
India VIX (NSE)
Reference volatility index for IV-regime context and term-structure benchmarking.
Historical Archive
EOD option-chain records for backtesting, IV rank, HV30, and historical GEX overlays.
INTERNAL TIER
Proprietary Quantitative Engines
GEX Engine
Computes dealer Gamma Exposure per strike using standard market-maker gamma models on NSE option-chain data.
DEX Engine
Aggregates net dealer delta across strikes and expiries; classifies regime and directional hedging pressure.
IV Surface Engine
Constructs the full implied-volatility surface via SVI/SABR calibration on live NSE option-chain data.
NLP Synthesis Engine
Language explanation layer — reads quantitative output only; cannot alter or override any computed metric.
03 · Methodology & AI Governance

Deterministic Math. A Read-Only AI Layer.

Arkenwell keeps a strict architectural separation between its deterministic quantitative pipeline and its natural-language layer. The two share a one-way data contract: the language layer reads quantitative outputs — it cannot write, modify, or influence any metric.

ARCHITECTURE CONTRACT
QUANT_ENGINE — computes GEX · DEX · IV · OI
↓ read-only data contract
NLP_SYNTHESIS_LAYER — explains, summarises, answers
The language layer never sits between you and the number. Every AI explanation is generated from the same computed metric shown on the panel — and can be checked against it.

04 · Engine Versioning & Auditability

Documented Methods. Reproducible Results.

Each quantitative engine carries a version number. When core methodology changes in a way that could affect interpretation, the version increments and users are notified — so the meaning of a metric never shifts silently underneath you.

Reproducibility

Every derived metric follows a documented mathematical method. Where possible, calculations can be reconstructed directly from the underlying raw NSE option-chain records — enabling independent, third-party audit.

Version Governance

Version numbers increment whenever core methodology changes in a way that could affect output interpretation. Major changes are communicated in advance, with a transition window to adjust workflows.

05 · Known Limitations

What Arkenwell Cannot Know

Radical transparency means disclosing the boundaries of our models, not just their strengths. Understand these before making any trading decision — they apply to every platform in this category, whether or not it says so.

01
Dealer positioning is estimated, not observed

True dealer inventory is private to each dealer's own risk systems. Our GEX/DEX models estimate hedging obligations using the standard market-maker gamma assumption — dealers net short options, hedging delta-neutral. Real behaviour can deviate in certain regimes.

02
Feeds can lag under peak load

Streaming feeds may encounter latency during peak volume — particularly the final 30 minutes before expiry and on high-volatility event days. Where delays are detected, the platform shows explicit status indicators and falls back to the next feed in the pipeline.

03
AI explanations are probabilistic

Natural-language summaries are generated by language models applying probabilistic inference. They can contain errors or misinterpretations. Always cross-reference AI text against the raw quantitative data shown on the same panel.

04
Historical reconstruction has gaps

Historical GEX/DEX overlays rely on periodic option-chain snapshots, not continuous tick recording. Intraday changes between snapshots are not captured, so reconstructed positioning may differ from actual intraday exposures.

06 · Security & Data Handling
