# Tape Profile

Where today's options trading landed, strike by strike, as gamma, delta, vanna or charm flow, or as call and put volume.

**Tape Profile** answers a different question from the open-interest widgets:
not where positions sit, but where today's trading happened. Each bar is one
strike's share of the session's options activity, expressed as gamma flow by
default. Green bars add long dealer gamma, red bars add short.

## What it shows

| Element | What it is |
|---|---|
| **Bars** | Today's flow at each strike, for the chosen greek |
| **GAMMA flow** (header) | The net of all bars |
| **Top + / Top −** (Details) | The strikes with the largest flow on each side |

In **Details**, **bars** switches between **Classified** (flow for the chosen
greek: delta, gamma, vanna or charm) and **Volume / Ladder** (call and put
contracts traded). The expiry scope is ≤90DTE, 0DTE or 1DTE.

Marked **(Beta)** in the widget picker: it is newer, and some of the options
data behind it can lag the live market by several minutes.

## Practical application

![Tape Profile widget, illustrative example: call trading at 27,250 and put trading at 26,900](https://q-bitf.com/docs-img/tape-profile.png "Illustrative example data, not a real session. NQ, gamma flow: net +784M; largest positive strike 27,250 (+126M), largest negative 26,900 (-97M), spot 27,075.")

**Reading it.** Today's net gamma flow is **+784M**. Most of it sits in a block
of green bars from about 26,950 to 27,300, and the single largest is 27,250 at
**+126M**: traders were active in the call wall strike all day. Below price
there is one red cluster around 26,900, with **-97M** at that strike alone.

**What it means.** Two strikes drew the day's attention: 27,250 above, where
the open-interest book already has its call wall, and 26,900 below, where put
trading concentrated at a level that had little open interest before. Today's
trading added to the ceiling and may be building a new level below.

**How to use it.**

- **Today's biggest strike matching the call or put wall:** the wall is being
  defended or added to; expect it to matter again.
- **A new cluster where open interest is thin:** a level is forming. Mark it,
  and check [Open Interest](https://q-bitf.com/docs/widgets/open-interest) tomorrow to see if
  the positions stayed open.
- **Switch to 0DTE** to see what is driving today's moves; same-day options
  move the most with price.
- **Volume / Ladder** shows the raw call and put contracts if you want counts
  rather than exposure.
