Altair® Panopticon


Price Band Graph Settings

The Pricing Band Graph displays the variance or spread between two time-based metrics.

Each grouping defined in the breakdown will be displayed as a separate layer of the overall graph, where typically color is used to display the category.

As it is expected that spread layers will occlude, the transparency is defaulted to 50% and can be modified as appropriate.

Typical use cases include comparing the pricing bid offer spreads from multiple liquidity providers.

The price band graph settings pane is displayed after clicking the Options  button.
