Delta Exposure (DEX) across NIFTY, BANKNIFTY and F&O option chains
Delta Exposure converts option open interest and delta into an estimated directional exposure profile by strike. The dashboard compares call and put contributions, modelled neutral levels and available customer or dealer sign conventions.
Check the selected expiry, units and sign convention before interpreting a peak or zero crossing. OI does not identify actual dealer inventory, so hedge-flow and support or resistance readings depend on model assumptions. Compare the profile with spot, IV and changes over time; a concentration is not proof of institutional absorption or a future price target.
How is DEX different from GEX?
DEX is the level — the directional delta position embedded in open interest right now. GEX is the rate of change — how fast that position re-hedges as spot moves. DEX answers 'which way is the book leaning'; GEX answers 'will hedging dampen or amplify the next move'. Used together they map both direction and regime.
Why can Net DEX be positive while the market falls?
DEX describes the standing hedge landscape, not a directional forecast. A long-delta-crowded book can accelerate a decline as those positions unwind. That is exactly why the negative-gamma + call-heavy-DEX quadrant is flagged as unwind risk on this page.
What is the Delta Neutral Level and how should I trade around it?
It is the modeled spot level where the option book's net delta flips sign. Treat it like a regime line: oscillation around it favors range tactics; clean acceptance through it, especially with supporting DEX flow, favors continuation in the breakout direction.
Which view should I use — Customer or Dealer?
Customer view shows the raw OI-weighted delta of open positions (calls positive, puts negative) and is convention-free. Dealer view flips the sign under the short-calls/long-puts assumption to approximate the hedging book. Start with Customer for structure, toggle Dealer when reasoning about hedge-flow direction.
Why do different platforms show different DEX numbers?
Because DEX is modeled: platforms differ on sign conventions, whether they use exchange or model deltas, lot-size and spot scaling, and which expiries they aggregate. Compare the shape and the key strikes rather than absolute magnitudes.
Does delta divergence prove that institutions are absorbing orders?
No. This dashboard compares spot with OI-derived DEX flow and identifies a statistically meaningful mismatch consistent with absorption. Because the option-chain feed does not classify buyer- versus seller-aggressor volume, confirm the highlighted zone with rejection/reclaim price action before trading it.

Understanding Delta Exposure for Options Trading
This dashboard answers the question GEX alone cannot: which way is the option book actually leaning right now.
Delta exposure (DEX) aggregates the directional exposure embedded in open interest at every strike, turning the chain into a map of rupee delta notional. DEX is the level; GEX is the rate of change. Together they describe both the direction and the violence of dealer hedging.
In the India market this matters most in NIFTY and BANKNIFTY weeklies, where intraday OI updates make DEX flow a genuinely real-time signal and where expiry-day charm effects mechanically drag price toward heavy DEX strikes in the final hours.
How Traders Should Use It (Intraday Workflow)
Read the Quadrant First
The DEX × GEX card classifies the session — pinned grind, supported range, fragile longs, or squeeze fuel — before you pick fade or continuation tactics.
Mark the Shelves
Peak call DEX strike is the resistance shelf, peak put DEX strike the support shelf. These are your operating boundaries.
Track the Delta Neutral Level
Oscillation around it favors range trades; acceptance through it flips the hedge-flow direction and favors continuation.
Confirm with DEX Flow
A rally without positive DEX flow is unsponsored and fade-prone; a decline into rising net DEX flags accumulation.
Respect Expiry Drift
Inside the last day, charm dominates — expect gravitation toward heavy DEX strikes unless news breaks the structure.
India-Specific Execution Notes
Revalidate After Gap Opens
A large gap re-prices every delta in the chain; the DEX map from yesterday’s close is stale until strikes reprice.
Writers Weaken the Dealer Assumption
Heavy Indian retail option writing means the dealer-view sign flip is a scenario, not a certainty — trust the strike map over the aggregate sign.
Be Stricter on Stock Options
Thin chains produce unstable deltas and unreliable DEX; demand clear OI concentration before trusting levels.
Event Days Override Structure
RBI, Budget, CPI, and global shocks can overwhelm hedge mechanics; downgrade DEX confidence accordingly.
