What is Internal Flow?

Internal Flow, also sometimes referred to as Intrabar Flow, refers to volume activity taking place inside candles.

This is fundamentally different to regular volume, which only reveals the net sum of the candle volume.

In this article we will explore how Internal Flow works in SubFlow Terminal, what information it tells us and how to take advantage of it.

Internal Flow in SubFlow Terminal

Internal Flow shines an X-ray vision, revealing unusual volume activity and aggressive large trades developing inside candles.

Internal Flow is visualized in an intuitive heatmap style. Brighter colors correspond to higher, more extreme volume.

In this example we can see how moderate, high and extreme volumes are visualized.

Aggressive trading positions exposed

Similarly to Value Area and Point of Control, Internal Flow gives us information about positioning of traders.

Key difference between the two is that instead of revealing where majority of trading interest is located, Internal Flow reveals where aggressive, high value trades are developing.

Internal Flow in stock market

By default, TradingView displays stock market charts only for regular trading hours (when stock market is open).

This means Internal Flow will not have access to all volume data available beyond regular trading hours to determine what "unusual volume" means.

On lower timeframe charts, this leads to sparse and inaccurate data.

Switching to electronic trading hours

Internal Flow will work properly once we switch "Regular trading hours" to "Electronic trading hours" on TradingView's chart settings.


  1. Open any stock chart, right click canvas and select Settings

  2. Navigate to "Data modification" under Symbol tab

  3. Select "Electronic trading hours"

  4. Click "Ok"

How to trade Internal Flow

When we evaluate Internal Flow with the context of price action, we can detect hidden insights such as where traders were likely liquidated, selling in extreme fear or buying in extreme greed. The dumb money, if you will.

However, Internal Flow can also be used to identify how more informed players have positioned - the smart money.

Consolidating price followed by a sudden move up or down with aggressive flows can indicate strong conviction found after uncertainty in the markets, marking a beginning of a new trend.

You're flowing through the lessons ๐Ÿ’ช

Internal Flow is fairly easy to understand and identify, the brighter the color, the more extreme activity is taking place inside the candle.

By combining this with price action, we get lots of valuable clues for identifying what the dumb and smart money are doing.
