How Informed Takers Create Toxic Flow for Market Makers and AMMs
Summary
This article explains why collecting the bid-ask spread does not guarantee that liquidity providers will profit. Takers can wait for favorable conditions, while makers continuously expose quotes; informed takers may therefore trade just before prices move against the maker. The article cites short-term S&P 500 futures profit-and-loss by counterparty type, where aggressive high-frequency traders earned while passive high-frequency and opportunistic groups fared worse. It attributes this gap to information and trading horizon, distinguishing tactical traders from participants seeking longer-term fills.
It identifies latency and broader venue coverage as sources of toxic flow, then illustrates how cross-market signals and simultaneous trading can exploit stale quotes or remove hedges. For automated market makers, it discusses fee design, trader segmentation, adjustable pricing curves, faster oracles, and dynamic parameters as possible defenses. These are proposed mechanisms, not a demonstrated universal solution. The discussion is conceptual, includes theoretical examples, and notes that many automated-market-maker trades may be arbitrage-driven; it does not provide a quantified comparison of defenses or establish which parameters yield sustainable returns.
Key ideas
- A maker’s spread and fee income can be outweighed by losses to better-informed takers.
- Takers can exploit faster venue access or broader visibility into liquidity and activity.
- Cross-venue trading can remove hedges and force liquidity providers to reprice.
- Automated market makers may respond through fees, pricing parameters, or faster price updates.
- The article presents possible defenses but does not establish a proven solution for DeFi liquidity providers.
