Live Option Chain Analysis

The option chain holds the market's positioning — where calls and puts are written, how open interest is shifting, and which strikes act as walls. Charteq turns the raw chain into one live dashboard: per-strike OI and ΔOI, PCR, max-pain, call/put walls, and gamma/GEX.

Everything is factual, derived from the live chain — no tips.

What to read in the chain

Open interest shows where positions are concentrated; the change in OI (ΔOI) shows where fresh writing or unwinding is happening now. The call wall (max Call OI) is resistance; the put wall (max Put OI) is support; max-pain is where option holders lose most at expiry.

Gamma / GEX

Gamma exposure (GEX) shows where dealer hedging can dampen or amplify moves. The zero-gamma level separates a calmer, mean-reverting regime (above) from a more volatile, trending one (below). Charteq marks it live.

FAQ

What is option chain analysis?

Reading the option chain's open interest, OI change, PCR, max-pain and walls to see how calls and puts are positioned — where resistance and support are being built by writers.

What are call and put walls?

The call wall is the strike with the most Call OI (resistance); the put wall is the strike with the most Put OI (support). Large walls mark heavy writer positioning.

What is GEX / gamma flip?

Gamma Exposure measures dealer hedging pressure. The gamma-flip (zero-gamma) level separates a calmer regime above from a more volatile one below the spot.
