Strike Seller View
How to Read Strike Seller View
A framework for evaluating possible option-writing pressure through premium, OI, volume, PCR, and strike behavior.
Most important nuance
Falling premium with rising OI can be consistent with writing, but spreads, hedges, and other participants can create the same footprint.
What It Tracks
Review CE and PE behavior at each strike.
Best Comparison
Compare premium change with OI and volume.
Strongest Use
Anchor activity to ATM and the underlying.
Main Risk
Track whether a potential seller zone holds or rotates.

Terminology Traders Actually Need
Seller-Side OI Change Writer Activity View+
The seller view interprets strike-level call and put OI changes together with premium behavior and the underlying.
Market Reading
Look for rising OI with premium weakness as possible writing context, then compare the opposite side and nearby strikes.
India Market Context
Weekly index options can show rapid writing and covering around ATM as Indian expiry approaches.
Caveat
OI and premium patterns suggest positioning behavior but cannot identify every trade initiator.
Strike Defense Persistence Test+
Strike defense describes repeated seller activity near a level while the underlying fails to move through it.
Market Reading
Use per-strike charts, the signal strip, and OHLC response across multiple snapshots.
India Market Context
Round-number index strikes often attract concentrated activity because liquidity is deepest there.
Caveat
A defended strike can fail suddenly when covering or directional demand accelerates.
Seller Exit or Roll Position Migration+
Falling OI or activity moving to another strike can indicate covering, expiry roll, or a shifted defense level.
Market Reading
Compare neighboring strikes and the full-session timeline before labeling an exit.
India Market Context
Indian weekly expiry rolls can transfer activity to the next contract or a new ATM strike.
Caveat
Migration does not by itself reveal whether the original seller made or lost money.
How to Use This Page
Choose a Focused Strike Range
Start at ATM or ATM plus nearby strikes so the seller map stays relevant to spot.
Compare CE and PE Seller Behavior
Read OI change and premium action on both sides rather than one strike alone.
Validate With Underlying OHLC
Check whether price respects, tests, or breaks the identified seller concentration.
Use Display and Session Controls
Adjust layout, PCR overlays, time filtering, and historical mode to verify persistence.
Frequently Asked Questions
How does this page infer option selling?+
It combines OI and premium behavior as a positioning heuristic; exchange data does not label every trade as buyer- or seller-initiated.
What makes a seller level stronger?+
Persistent activity, liquid strikes, neighboring confirmation, and repeated underlying rejection strengthen the interpretation.
What indicates possible seller covering?+
OI reduction, premium expansion, a broken strike level, or activity migrating elsewhere can indicate covering.
Why keep the underlying OHLC visible?+
Seller positioning is only useful when tested against the actual price path and timing.
