Algorithmic Execution Bias

Algorithmic Execution Bias occurs when automated trading systems prioritize certain execution strategies that skew market outcomes. For instance, if many algorithms use the same volume-weighted average price model, they may cluster their trades, creating artificial price pressure.

This bias can distort the natural supply and demand dynamics of an asset. It often leads to predictable patterns that other, more sophisticated algorithms exploit.

In the context of market microstructure, this bias affects how prices are discovered and how liquidity is distributed. It is a result of herd behavior among programmed entities.

Understanding this bias helps traders identify when price action is driven by code rather than fundamentals.
