Statistical Process Control
Statistical process control is a methodology used to monitor and control a process to ensure it operates at its full potential. In trading, this means tracking the performance of execution algorithms or data feeds to detect when they deviate from expected parameters.
By using control charts and statistical tests, traders can identify when an algorithm is underperforming or when a data source has become noisy. This allows for timely intervention, such as switching to a backup data feed or pausing an execution strategy.
It is a disciplined approach to managing the operational risks of algorithmic trading. Statistical process control provides a framework for continuous improvement and stability in volatile markets.
It ensures that the trading system remains within predefined safety and performance bounds. This technique is widely used in industrial engineering and has been successfully adapted for financial systems.
