Time-in-Queue Decay

Context

Time-in-Queue Decay, within cryptocurrency derivatives, options trading, and financial derivatives, describes the diminishing value of a pending order as it remains in a queue awaiting execution. This phenomenon arises primarily in environments employing Fair Order Flow (FOF) or similar mechanisms where order prioritization is based on price-time priority, and latency impacts order fulfillment. Consequently, orders that experience prolonged queuing periods may see their intended execution price become less favorable due to market movement, effectively eroding their potential profitability. Understanding this decay is crucial for algorithmic traders and market makers seeking to optimize order placement and minimize adverse selection.
