Data Provenance

Analytics are derived from live NSE options data. Each session carries an internal audit reference so derived values can be traced back to the source feed rather than to an unattributed model output.

Session Isolation

Terminal sessions are scoped per authenticated user. Watchlists, alert thresholds, workspace layouts, and command history are namespaced to your account and are not shared or aggregated across accounts.

Reliability Posture

The terminal is designed for continuous availability during NSE market hours. Feed anomalies and ingestion gaps are monitored and surfaced in-session. Public status updates are posted for material incidents.

Data Ownership

You retain ownership of the analytics outputs, exports, and configurations produced in your session. Aggregate, anonymized usage telemetry is used for platform reliability and is not resold or licensed.

Access Controls

Access is protected by session-bound tokens with configurable timeout. Sign-ins from separate devices are logged independently. Professional runs one active terminal at a time and Professional+ runs two, on two different devices — if you reach the limit, signing in shows your open terminals and lets you sign one out from there, so you are never locked out. Additional controls such as SSO are available on request for team accounts.

Model Transparency

Every derived analytic — Gamma Flip, DEX aggregation, dealer positioning, pressure engine — has a published methodology note describing inputs and formula. We do not ship opaque, unattributed indicators.

Live GEX, DEX, and Open Interest feeds on Professional and above are sourced directly from NSE's real-time OI dissemination with a sub-second ingestion pipeline. Explorer tier receives a 15-minute delayed snapshot. Latency figures are session-dependent and may vary during high-volatility expiry windows.

GEX in Arkenwell is computed from live strike-level open interest combined with Black-Scholes delta approximations refreshed per tick. It is not sourced from a third-party model vendor. The Gamma Flip level is derived from our net delta-weighted OI crossover algorithm, which may differ from simplified GEX calculators by up to ±0.3% in high-skew environments.

Yes. A 3-day trial of the Explorer tier is available with no credit card required at signup. The trial provides full access to live GEX, PCR, DEX, and knowledge center features under real market conditions. Advanced algorithmic engine commands and live signal desks are Professional exclusive.

There is no lock-in period. Subscriptions are billed monthly and can be cancelled at any time from your account portal. Cancellations take effect at the end of the current billing cycle — you retain full access until that date. No partial-month refunds are issued, and downgrade to Explorer (free tier) is always available instantly.
