# Dark Pool Activity

Weekly dark-pool share volume, average print size and the venues carrying the most activity.

The **Dark Pool Activity** widget shows reported off-exchange activity for a
listed stock or ETF, one reporting week at a time. Futures and cash indexes use
their listed proxy: ES and SPX use SPY, NQ and NDX use QQQ, and GC uses GLD.

## What it shows

| Readout | Meaning |
|---|---|
| **ATS shares** | Shares reported across dark-pool venues during the week |
| **ATS trades** | Number of reported trades during the week |
| **Average print** | Average shares per reported trade |
| **Recent vs prior** | The recent half of the selected window compared with its earlier half |
| **Top venues** | Each venue's share of the latest reported week's activity |

Switch the chart between **Shares** and **Trades**, then choose a four-to-52
week window. The average-print line keeps clip size visible while activity
changes.

## How to use it

- Compare weekly volume with average print size. Rising volume with larger
  clips indicates a different participation profile from rising volume made
  of many smaller trades.
- Use the venue list to see whether activity is broad or concentrated in a few
  pools.
- Compare the latest week with the recent trend instead of treating one spike
  as a signal.
- Use this as positioning context. It does not identify trade direction and is
  not an intraday timing tool.
