See where the dealer book stands, strike by strike, every second.
FirmTape rebuilds the SPX dealer gamma book from every options print while the session trades. The flip, the walls and the strikes that keep standing out are drawn on the chart beside a ladder of every strike, in three books. Alerts watch the levels for you, ASK answers from the same numbers, and the levels follow you into your own platform.
LIVE: today's session every second, alerts, ASK, the levels API and the platform integrations, and 5 LAB credits a month. Every finished session is free in REPLAY.


The problem
A gamma level printed once a morning is stale by the first hour.
- The flip and the walls move as the day trades, and a number from the close says nothing about where they sit at 11:00.
- A level only helps if you are looking when price gets there, and nobody watches four symbols all session.
- A level without its size, its distance and its book is a line you cannot weigh, and copying it by hand into another platform makes it stale again.
With LIVE
The book, rebuilt every second, watched for you, wherever you chart.
LIVE measures the SPX book from the tape itself, once a second, in three books. Every wall and level is drawn with its weight, its distance from price and the moment it came in. A line on any level fires to Telegram, your phone or your server; ASK reads the minute on screen in plain words; the OPTIONS tester puts a structure against the same book; and the same flip and walls refresh themselves in your platform.
How it works
Step by step
-
01 / 04
Draw the walls and levels
WALLS puts each book's call wall and put wall across the chart; LEVELS adds the strikes that keep standing out. Every line is named at its left end and plated on the price scale, its width the share of the book it carries.

-
02 / 04
Read the ladder in any book
Click a ladder column's head. Its card picks the book (VOL, OI, MEAS), the expiry, the metric and the window, so you see the gamma on every strike, level with its price.

-
03 / 04
Put an alert on a level
Right-click near a wall or the flip and pick Alert when price reaches that level. The line follows it as the book moves and fires to Telegram, your phone or your webhook.

-
04 / 04
Ask about the screen
Press ASK (Cmd+\) and type
In the guide/levelsor a question in plain words. It reads the symbol, the day and the minute on screen and answers from these same numbers, with the levels it cites as cards.

What you can do with LIVE

Walls and levels that carry their weight
Width is the strike's share of the book, fade is its distance, and a tick marks when it came in.

FAQ
Questions about LIVE
- Does LIVE tell me which way SPX will go?
- No. Direction was tested three ways on this data and is not there. LIVE measures where the book stands and how far price may travel; it never says which way to face.
- What is the difference between the three books?
- The volume book is built from the day's 0DTE volume, the conventional public object. The open-interest book uses yesterday's positions over four expiries. The measured book signs every print against the prevailing quote, a read no public feed offers.
- How often is the book rebuilt?
- SPX every second during the session. About a hundred more tickers are read from whole-chain snapshots every five minutes, and the chart says which cadence a symbol has.
- What do the alerts send?
- The price, the time in New York, the flip and both walls of the book at that second, and the book it read, to Telegram, a phone notification or your webhook. Never a trade call.
- Is ASK included?
- Yes. ASK is included in every paid plan, fifty questions a day; the slash commands other than /history answer without spending one.
- Does the OPTIONS tester cost extra?
- Building and reading a structure is free. Testing it over the archive spends 10 LAB credits, and LIVE includes 5 LAB credits a month.
- Can I see the levels in my own platform?
- Yes. The levels API and the platform integrations are part of LIVE: make a read-only token under Account, Integrations.
- What is free?
- Every finished session, with the same chart and every layer, in REPLAY. LIVE is today's session as it trades, and what is built on it.
What it does not do
- It does not draw entry arrows or trade calls, in the chart, an alert, an ASK answer or the tester: there is nothing honest to put in them.
- It does not claim a wall holds or breaks: whether price is drawn to strength has not been measured.
- It does not alert on the premarket estimate or on the side of a print, and it does not run outside the regular session.
