# Darkpool

> Read dark pool prints with EchoScore, Block/Unusual/@Magnet/Accum badges, per-ticker rollups, and the Snapshot levels view.

Dark pools are private venues where institutions execute large stock trades away from the public order book. Trade Echo streams those **prints** live and scores them - so instead of a wall of rows, you see which prints actually matter and **at what price levels** institutions keep transacting.

## What a print tells you

Each row is one dark pool trade: ticker, size, price, notional amount, and time. Individually a print is just a data point. In aggregate, repeated size at the same price marks **levels institutions care about** - which is what the Snapshot view is built around.

---

## EchoScore

Every print gets an **EchoScore (0-1)** - print significance derived from **notional size, relative volume, and share of the day's volume**. The score renders as a gradient bar: amber for routine prints sweeping to green for standouts.

Use the **min-score quick filter** (0.50+ / 0.70+ / 0.90+) to cut the feed down to prints worth a look. A 0.90+ print on a mid-cap name is rare - that is the tape talking.

## Badges

Prints can carry up to four badges:

| Badge | Meaning |
|-------|---------|
| **Block** | Notional of **$100M+** in a single print |
| **Unusual** | Print size is **3x or more** the ticker's 30-day average volume |
| **@Magnet** | The print sits at a price level that keeps attracting repeated dark pool activity |
| **Accum** | The ticker is showing an ongoing accumulation pattern |

Block and Unusual are derived from the row itself; @Magnet and Accum come from Trade Echo's accumulation engine watching activity over time. You can filter the feed by badge.

## Views and quick filters

The view dropdown switches between **All prints**, **$50M+**, **$100M+**, and **Snapshot**.

On All Prints, quick filters narrow by **premium** ($1M+ / $10M+ / $50M+ / $100M+) and **size** (10K+ / 50K+ / 100K+ / 500K+) alongside the EchoScore filter. Search and filters apply to every page of results, not just the page on screen.

### Per-ticker rollup

Focus a ticker and a **rollup strip** appears: 30-day average and last-day dark pool premium (from nightly rollups) plus today's **active level** and spot price. It answers "is today's activity normal for this name?" in one glance.

## Snapshot view

Snapshot turns prints into **levels**:

- **Levels rail** - the price levels with the most dark pool premium, ranked; sort by premium, print count, or cluster size
- **Premium profile** - how premium distributes across price, so you can see where the volume actually sits relative to spot
- **Chart panel** - price with dark pool levels overlaid
- **Window and filter chips** - change the lookback window and minimum premium ($50M+ / $100M+ / $300M+)

## Trading with dark pool levels

1. Find a name with **Accum** or repeated **@Magnet** prints
2. Open **Snapshot** and note the top 2-3 levels near spot
3. Treat heavy levels as **support/resistance zones** - institutions defended them before
4. Confirm with [Dealer Edge](https://tradeecho.com/docs/features/dealeredge/quick-start) (do gamma walls agree?) and [OptionFlow](https://tradeecho.com/docs/features/optionflow/quick-start) (is options money leaning the same way?)

Dark pool prints are **not directional by themselves** - a print records a trade, not whether the initiator was buying or selling. Levels plus confirmation is the edge.

## Web and mobile

Darkpool is available on **web and mobile**. The Snapshot levels view and per-ticker rollup strip described above are the web experience; mobile carries the live prints feed.
