Summary
Market Depth Volume summarises the visible quantity on the bid and offer sides of the Orderbook across the displayed levels.
How to read it
Compare the buy-side and sell-side totals to understand where visible interest is concentrated. The totals include only the levels currently shown and may change as orders are entered, amended, executed, or cancelled.
Things to keep in mind
Visible depth is not the same as guaranteed liquidity. Hidden orders, other venues, and rapidly changing orders can affect the quantity available when a trade is placed.
