How Does the Use of High-Frequency Trading (HFT) Algorithms Relate to Front-Running Accusations?
HFT algorithms, designed for speed, can exploit minor price discrepancies and information asymmetries. While not all HFT is front-running, some HFT strategies involve detecting large pending orders (e.g. in the mempool or through order book changes) and trading ahead of them.
This practice, often called 'order anticipation,' blurs the line between legitimate speed advantage and illegal front-running, leading to frequent accusations.
