Heatmap​

The Heatmap visually represents both current and historical liquidity in the order book.

You can see the scale of the Heatmap in the toolbar.

  • The redder the colour, the higher the liquidity.
  • Colder (or bluer) colours – ending with dark blue – indicate lower liquidity.
  • You can also change the intensity of the heatmap colors or use greyscale.

Volume Dots​

Volume dots depict trade volume at specific prices, with larger dots indicating more volume. For volume dots:

  • Bid aggressors are green.
  • Ask aggressors are red.

Learn more about Volume dots and their settings in this article or this video.

Volume Bars​

Volume bars show the traded volume within the bar timeframe. In other words, from the left edge of the bar to the right edge.

Best Bid and Ask and Last Price​

Best bid and offer lines (BBO) mark prices for the highest buyers and lowest sellers.

The Last Price refers to the most recent price at which a trade was executed. This value is continuously updated in real time as trades occur in the market.

You can switch between two modes for displaying the BBO and Last Price lines:

  • Show only the last value in a pixel: This option simplifies the chart, making it cleaner, but it does not capture peak values within each pixel.

  • Reflect the price range for each pixel: This option displays the exact minimum and maximum values, providing precise details, though it may result in a noisier chart.

To toggle between these modes, enable or disable the "Show min/max for BBO/Last Price" option in the configuration pop-up.
