01. Command Center Fundamentals
The Arkenwell Command Center is the keyboard-first control layer for navigating market data, derivatives analytics, quantitative models, alerts, and terminal workspaces.
It is designed to reduce navigation overhead and keep analysis inside a single, consistent command workflow. Commands are parsed in real time, security symbols are resolved dynamically against NSE symbology, and supported analytics are connected to Arkenwell live market-data and telemetry layers.
Open the Command Center
Use the Command Center from any Arkenwell view:
•
/ — Open Command Center
•
Ctrl + K — Open on Windows/Linux
•
Cmd + K — Open on macOS
•
Esc — Dismiss and return to the active workspace
•
↑ / ↓ — Navigate command history
•
Enter — Execute the active command
Commands highlighted throughout this guide can be entered directly into the Command Center.
Command Syntax Structure
Arkenwell commands follow a consistent syntax structure:
[ACTION / METRIC] [SYMBOL] [PARAMETERS / CONDITIONS / THRESHOLDS]Command rules
•
Case-insensitive
Commands are not case-sensitive. For example:
gex nifty · Gex Nifty · GEX NIFTYall resolve to the same command.
•
Global commands
These require no symbol:
VIX · REGIME · SWEEPS · CLEAR · HELP•
Symbol-bound commands
These apply an analytical function to a specific security:
GEX NIFTY · PCR BANKNIFTY · QUOTE TCS · CHAIN AXISBANK•
Multi-asset commands
These evaluate relationships between securities:
KALMAN HDFCBANK ICICIBANK•
Conditional commands
These define a metric, operator, and threshold:
ALERT SET NIFTY PCR < 0.8 · ALERT SET NIFTY GEX < 002. Market Data & Options Chains
Use these commands to move directly from the Command Center into live quotes, options chains, and derivatives data.

•
PCR > 1.30 — Bullish support bias

These commands expose the positioning and hedging metrics used to interpret options-market structure.
GEX <SYMBOL> — Net Gamma ExposurePurpose
Estimate aggregate dealer gamma exposure across active option strikes.
Screen output
•
Aggregate Net GEX
•
Strike-by-strike GEX profile
•
Positive/negative gamma balance
Reference interpretation
•
Positive GEX: A positive gamma environment is generally associated with dealer hedging that can dampen directional moves and support mean-reverting price behavior.
•
Negative GEX: A negative gamma environment can increase the sensitivity of dealer hedging to price movement and may reinforce directional momentum.
Examples
GEX NIFTY · GEX BANKNIFTY · GEX AXISBANK · GEX RELIANCEGFLIP <SYMBOL> — Gamma Flip LevelPurpose
Identify the price level at which aggregate modeled gamma changes sign.
Screen output
•
Gamma Flip price
•
Distance from spot
•
Percentage distance
•
Current gamma regime
Reference interpretation
•
Spot above Gamma Flip: The modeled environment is generally associated with lower volatility and stronger mean-reversion characteristics.
•
Spot below Gamma Flip: The modeled environment can indicate greater volatility sensitivity and stronger directional hedging pressure.
Examples
GFLIP NIFTY · GFLIP BANKNIFTYWALLS <SYMBOL> — Call Wall & Put WallPurpose
Identify major option strikes that may act as structural boundaries.
Working mechanics
The engine scans the option chain for significant call- and put-side concentration using open interest and modeled gamma exposure.
Screen output
•
Call Wall
•
Put Wall
•
Current spot position
•
Distance to each boundary
•
Structural range visualization
Reference interpretation
•
Call Wall: A major call-side concentration that may act as overhead resistance under normal conditions.
•
Put Wall: A major put-side concentration that may act as downside support under normal conditions.
Examples
WALLS NIFTY · WALLS BANKNIFTYDEX <SYMBOL> — Dealer Exposure IndexPurpose
Quantify modeled dealer inventory stress and hedging sensitivity around near-the-money strikes.
Working mechanics
The engine evaluates dealer delta sensitivity to a 1% change in the underlying and normalizes the result to a -100 to +100 scale.
Screen output
•
DEX value
•
Hedging-risk indicator
•
Directional vulnerability
Examples
DEX NIFTY · DEX BANKNIFTY · DEX AXISBANK04. Volatility & Risk Pricing
Use these commands to evaluate implied volatility, volatility skew, and the broader market volatility environment.
IVR <SYMBOL> — Implied Volatility RankPurpose
Place current implied volatility within its 52-week historical range.
Screen output
•
0–100 IVR gauge
•
52-week IV range
•
Historical context
•
Strategy reference tags
Reference interpretation
•
IVR < 20 — Historically low implied volatility
•
IVR 20 – 50 — Normal historical range
•
IVR > 70 — Historically elevated implied volatility
IVR is a historical positioning measure and should be interpreted alongside expiry, liquidity, realized volatility, and event risk.
Examples
IVR NIFTY · IVR BANKNIFTY · IVR HDFCBANK · IVR RELIANCESKEW <SYMBOL> — 25-Delta Volatility SkewPurpose
Measure the relative pricing of downside and upside out-of-the-money options.
Screen output
•
Volatility smile
•
25-delta skew
•

Reference interpretation
A steeper positive skew generally indicates stronger demand for downside protection. A flatter skew may indicate comparatively lower demand for downside insurance or stronger demand for upside exposure.
Examples
SKEW NIFTY · SKEW BANKNIFTYVIX — India VIX MonitorPurpose
Monitor the implied market expectation of near-term NIFTY volatility.
Screen output
•
India VIX
•
Daily percentage change

These commands provide statistical and model-based views of price relationships and market regimes.
KALMAN <SYM1> <SYM2> — Dynamic Kalman Filter Pair ModelPurpose
Model time-varying statistical relationships and dynamic hedge ratios between two securities.
Working mechanics
The model estimates a dynamic hedge ratio across the selected pair in real time without relying on a fixed lookback window.
Screen output
•
Dynamic hedge ratio
•
Current spread
•
±1σ, ±2σ, ±3σ bands
•
Mean-reversion signal
Reference interpretation
A spread extending beyond ±2σ may indicate a statistically unusual divergence. The result is a model signal, not a guarantee of mean reversion.
Examples
KALMAN HDFCBANK ICICIBANK · KALMAN TCS INFY · KALMAN TATAMOTORS MARUTIZSCORE <SYMBOL> — Rolling Statistical Z-ScorePurpose
Measure the distance between the current price and its rolling mean in standard-deviation units.
Screen output
•
Current Z-score
•
Historical distribution
•
Statistical boundary levels
Reference interpretation
•
Z > +2.5 → Strong upside extension
•
Z < -2.5 → Strong downside extension
These thresholds indicate statistical extension rather than a guaranteed reversal.
Examples
ZSCORE NIFTY · ZSCORE BANKNIFTY · ZSCORE RELIANCEREGIME — Market Regime ClassifierPurpose

Working mechanics
Reads the live option chain. Volume z-score is measured against each contract's own prior sessions from the NSE bhavcopy and shows "—" when there is not enough history. The chain reports totals per contract, not individual trades, so this is a turnover ranking, not a trade-by-trade tape.

The analytics and thresholds described in this guide are designed as market-structure and decision-support tools. Metrics such as GEX, DEX, PCR, IVR, skew, Z-score, Gamma Flip, and regime classification should be interpreted in context rather than treated as standalone predictions or guaranteed trading signals.
