Client Portal includes a dedicated “ON/OFF toggle for "Last Size Extra Decimal" display behavior. It can be accessed from clicking the User icon from top-right corner:
- OFF (default): Client Portal reads the "Last Size Extra Decimal" setting configured in Trader Workstation, IBKR Desktop, or IBKR Mobile and formats the Last Size values accordingly. The tooltip on hover will show the unformatted raw Last Size.
- ON: Client Portal ignores the decimal formatting setting and displays the unformatted raw Last Size directly in the UI. The tooltip behavior also reflects the raw value.
This toggle gives Client Portal users a quick way to switch between formatted and raw Last Size display without modifying the underlying setting in other platforms.
