Shows the daily share of a stock's volume reported off the exchanges, as a percentage line in a lower pane, from public daily off-exchange volume data.
In plain English
What it shows
- A lower pane with the daily percentage of a stock's volume that was traded off the public exchanges.
- It uses public daily volume data.
How traders use it
- See whether the off-exchange share is high or low compared with recent days.
- Compare spikes in the share with big days on the price chart.
What it does not tell you
- It shows a share of volume, not the direction of the trades.
- Daily charts only, for listed stocks and ETFs in the data.
Overview
Off-exchange Volume draws one line in a pane below the chart: the percentage of each day's volume that was reported off-exchange (dark pool / ATS and other off-exchange trades), meaning trades done away from the exchanges. A status line shows when the data was refreshed.
How it works
The data comes from public daily off-exchange (dark pool / ATS) volume data, which lists the total off-exchange volume reported for each symbol each day. The indicator divides that by the chart's volume for the same day and plots the result in percent.
If the result would be above 100%, the chart's volume is not the consolidated count, so nothing is drawn for that day. The data file is refreshed once a day, in the US evening.
How to use it
- Some traders watch for days when the off-exchange share is unusually high or low for that stock.
- Use it to see how much of a stock's trading happens away from the exchanges over time.
- Some traders compare the share with price moves on the same days.
These are ways some traders read it, for learning. They are not trade signals.
