Depth of Market (DOM) is a trading platform feature that provides traders with real-time visibility into the number of buy and sell orders for a specific financial instrument at various price levels. Typically, the DOM displays the number of buyers and sellers willing to trade at each price level, as well as the size of their orders. This information can help traders to identify potential support and resistance levels, assess the overall market sentiment, and make informed trading decisions. The DOM is particularly useful for traders who trade frequently and require accurate and up-to-date information on supply and demand dynamics in a specific market.
