For humans.
And their agents.

Read-only by default. We do not trade for you.

One bench, one camera: a reading head counts $62.4M of premium as a punched tape runs through it, and the recorded Option Trades page behind it shows the prints; the lit print peels off and feeds a rack of three glass tubes that ranks the day's contracts, then the recorded Contract Rank page shows the put as #2; a token becomes the put-wall pin on a comb that takes the shape of positioning, then the recorded structure chart shows the put wall at $770; a cable runs to a box marked MCP and the recorded Claude Code session shows the same rows; the objects fold into the mark.

Data from the venues options traders watch

Market data for a research routine. Rank the session, inspect the prints behind the move, read the structure by strike, and let your own agent ask the same tables through MCP.

01

Read the tape.

Every print as it hits the tape: side, strike, premium, size and open interest in one row, with the session and date attached, so the move can be checked print by print.

02

Rank the money.

Symbols and contracts ranked by premium for the session, with flow direction, Vol/OI and IV rank beside them, so the one put that took $62.4M stands out from the noise.

Features

03

See positioning take shape.

Net GEX and open interest by strike, the walls and the spot on one chart, read as context for the tape rather than as a target.

How the workflow stays honest.

The interface keeps observation, modeled context, and remaining uncertainty separate so a useful signal is never presented as a guaranteed outcome.

Session and date stay attached

Ranks and recaps remain tied to a dated market session, so the context behind a result is visible when you review it.

Exact prints remain inspectable

Open the trades behind a rank, then check size, side, expiry, sentiment, and the specific contract instead of relying on a score alone.

Freshness and caveats stay visible

Delayed, snapshot, or prior-session inputs are labeled where they apply, and modeled GEX is presented as context rather than a directional promise.

Access boundaries are explicit

The free preview is visible before checkout; live mode, full depth, advanced filters, exports, and saved workflows are identified as Premium.

Every market figure on this page is from one recorded session: SPY, October 6, 2026, one put, 64 trades, $62.4M of premium.

Call walls, option flow, and GEX—explained.
