Ping orders, often referred to within the context of high-frequency trading (HFT) and electronic trading, are small-sized orders sent to an exchange, dark pool or other trading venue to gauge or "ping" the market for existing hidden orders or liquidity. By detecting these hidden orders, traders can gather information about the market's potential direction or interest levels.[1]

The advent of electronic trading and the evolution of market structure have paved the way for more sophisticated trading strategies. High frequency trading firms, in particular, utilize advanced algorithms and rapid order execution to capitalize on small price discrepancies and market patterns. One such strategy involves the use of ping orders to detect hidden or iceberg orders on exchanges.[2]

Regulatory Concerns[edit]

Some market participants argue that the use of ping orders can be manipulative or disruptive. They believe that by continuously sending out these small orders, traders can flood the market with "noise," making it challenging for other participants to discern genuine order interest. This can lead to concerns about market integrity and fairness. Given the potential for misuse, several regulatory bodies worldwide are closely monitoring the use of ping orders and other HFT strategies. While not inherently illegal, malicious or excessive use of ping order.[3]
