}Data
GEX by strike with key markers
Returns GEX data broken down by strike price, plus key markers (gamma flip, max
pain, positive/negative walls, max-volatility and max-stability price levels, spot
reference, aggregate totals) and a flat levels object.
Pass TOTAL as expiration to get all expirations combined. Use view=levels
for a compact response without per-strike arrays, or range_pct to trim the
strike arrays around spot. Counts as 1 request.

account dashboard.
Path Parameters
Crypto: bybit, deribit, okx, derive, binance, all / combined, or a +-joined
subset such as deribit+derive. TradFi tickers: tradfi (all and combined
are aliases). Use /exchanges for the live list.
Examples:
"all"
"deribit+derive"
"tradfi"
Symbol (case-insensitive), for example BTC or QQQ. Use /coins for the list.
Example:
"BTC"
Expiration in DDMMMYY format (e.g., 25APR26), an ISO date (2026-04-25) or TOTAL for all expirations.
Example:
"25APR26"
Query Parameters
full (default) returns per-strike arrays, markers and metadata. levels
returns only levels and metadata.
Available options:
full, levels With view=full, keep only strikes within +/- this percent of spot in the
per-strike arrays. Number in (0, 50]. No effect with view=levels.
Required range:
x <= 50Response
GEX by strike data
With view=full: gex_data, markers, metadata and levels.
With view=levels: levels and metadata only.
