Depth of Market (DOM)
Overview
The Depth of Market, also known as the order book ladder, displays all resting limit orders at each price level above and below the current market price. DOM analysis reveals where institutional participants have placed large orders, helping traders identify genuine support and resistance levels created by actual liquidity rather than historical price patterns alone.
Key Concepts
Bid side shows resting buy limit orders stacked below the current price. Ask side shows resting sell limit orders stacked above the current price. Large resting orders (icebergs) may be partially hidden and only revealed through execution. Order pulling and spoofing involve placing and cancelling large orders to manipulate perception. Thin levels in the DOM indicate price zones that may move through quickly. Stacked orders at a level suggest a defended price point.
Entry Signals
Large resting bids absorbing aggressive selling without price decline signals institutional defence. Thinning of the ask side above current price suggests resistance is weakening. Enter when aggressive market orders overwhelm visible resting liquidity at a level. DOM imbalance showing significantly more resting orders on one side paired with a footprint confirmation.
Exit Signals
Exit when large resting orders appear ahead of your target, blocking further price movement. Exit if the resting orders defending your entry level are pulled. Watch for spoofing patterns where large orders appear and disappear rapidly. Reduce position if the DOM shows liquidity drying up in your trade's direction.

Pro Tips
DOM analysis requires a live, real-time data feed and is most effective in regulated futures markets where order data is centralised. In crypto, DOM data is exchange-specific and fragmented. Be cautious of spoofing — large orders that disappear when price approaches are designed to deceive, not to execute.

Absorption & Exhaustion
Absorption occurs when large limit orders absorb aggressive market orders without allowing price to move. For example, price hits a level where heavy sell market orders are absorbed by even larger buy limit orders — the aggression is neutralised. Exhaustion is when aggressive buying/selling loses momentum, visible through declining delta and volume at price extremes.
Delta & Cumulative Delta
Delta is the difference between aggressive buying volume (market orders hitting the ask) and aggressive selling volume (market orders hitting the bid) within a candle or time period. Cumulative delta tracks the running total over time. Divergence between price and cumulative delta reveals whether rallies/selloffs have genuine buyer/seller conviction.
Value Area High / Low
The Value Area is the price range containing approximately 70% of a session's or period's total traded volume. The Value Area High (VAH) is the upper boundary and Value Area Low (VAL) is the lower boundary. These levels act as dynamic support/resistance and are central to market profile and volume profile trading strategies.
Order Book & Liquidity Analysis
Order book and liquidity analysis examines the distribution and behaviour of resting orders across all price levels to map where significant liquidity pools exist. By aggregating order book data over time through heatmaps and liquidity visualisations, traders can identify where large players intend to transact, anticipate areas of support and resistance, and gauge market microstructure health.
