What is Toxic Order Flow? Informed Volume & Adverse Selection Explained

What is Toxic Order Flow?

Toxic order flow refers to aggressive market orders submitted by informed institutional traders who possess superior speed, private information, or latency advantages. Because toxic flow consistently moves price adversely against liquidity providers, market makers immediately widen bid-ask spreads or withdraw depth to avoid being front-run and liquidated.

Origin:Informed institutional flow / HFT latency arbitrage
Affected Entity:Passive liquidity providers & Market Makers
Direct Market Result:Order book evaporation, spread blowouts, trend acceleration
