Attack on MM 2: Market Maker Order Book and Order Flow

"Attack of the MM 2: Market Maker Order Books and Order Flow" by Dave explores the dynamics of market making in crypto, focusing on the Limit Order Book (LOB) and order flow. The LOB is the market maker's battlefield, defined by depth, tick size, and the concept of price improvement—providing better prices than the current best bid/ask to create market value. Market makers profit from the bid-ask spread, which covers order processing costs, inventory risk (holding assets amid price fluctuations), and adverse selection risk (being exploited by informed "toxic" traders). The spread types include quoted, effective, and realized spread, with the latter factoring in future mid-prices to measure true profitability. Order flow involves managing incoming trades, with a focus on identifying "toxic flow" from informed traders who can cause losses. Market makers use metrics like VPIN (Volume-weighted Probability of Informed Trading) to detect one-sided pressure and respond by pulling quotes, widening spreads, or reducing order sizes to mitigate risk. The article hints at deeper institutional strategies in future installments.
