Simple, Transparent Pricing

Professional Plan (₹999/mo)

• Sub-Second NSE Stream: Live low-latency WebSocket feed for continuous tick updates without 15-minute delays.
• Black-76 Greeks: IV and Greeks solved on the put-call-parity forward for every listed strike, so dividends and rates need no guessing.
• Net GEX & Gamma Flip: Real-time Dealer Gamma Exposure (₹ Cr) surface, Call/Put walls, and automatic crossover alarms.
• Volatility Skew & Smile: 25-Delta volatility smile calibration, term structure curves, and intraday PCR accumulation tracking.
• Desktop HUD & Audio Alerts: In-session browser notifications and audible threshold alerts for key structural levels.

Professional+ Plan (₹1,999/mo)

• Everything in Professional: Retain full real-time derivative telemetry, full strike ladder Greeks, and live GEX surfaces.
• Unusual Activity: Flags option contracts trading far above comparable contracts in past expiries, with OI change, premium and buildup.
• Quant Studio: In-browser TypeScript editor for your own chart indicators, using the @arkenwell/quant script library; saved scripts can drive alerts.
• Off-Platform Alerts: Alerts are evaluated on the server and keep running while you are signed out, delivered to Telegram, Discord, email, browser push or a webhook.
• Kalman Filter Engine: State-space tracking of the spot–futures basis with z-score readings and a signal log.
• Two Terminals: Run your desktop and a second device at the same time.

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, 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.

GEX, DEX and open interest are computed from the live NSE option chain on every plan, the trial included. Index chains refresh every few seconds; stock chains refresh in rotation, every few minutes. Each desk shows how old its data is.

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 7-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 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.
