The real-time gamma exposure API
Call walls, put walls, the gamma flip and net GEX per strike - computed live from the full options chain and served as JSON your code can act on.
Included with every paid QuantWheel plan.

Dealer positioning, fully mapped
One GET for the headline levels, deeper endpoints when you need the whole surface - across strikes, expirations and time.
See where hedging concentrates
Break net GEX down by strike and expiration to separate 0DTE pinning from monthly opex magnets - and pull vanna and charm from the same engine.

Alerts on the flip, not after it
A dedicated events endpoint surfaces gamma flips and wall migrations as they happen - so your bots react to regime change instead of discovering it in the P&L.
- /v1/gex/eventsflip and wall-move events with timestamps
- /v1/gex/historyreplay how the walls evolved, for backtests
- formula=switch GEX formulas - the same knobs as the dashboard

Every paid QuantWheel plan includes the full GEX API.
Query any ticker
GET /v1/gex?symbol=SPY with your Bearer key returns live walls in milliseconds.
Tunable compute
Filter by expirations and delta range, or switch GEX formulas - the same knobs as the QuantWheel GEX dashboard, exposed as query params.
History included
Historical GEX snapshots ship with every plan - validate a strategy against how walls and flips actually moved before wiring it to live data.
