UK regulators wants algo traders to be aware of their impact on market integrity, potential conduct issues and reduce market abuse risks
Financial Conduct Authority and Bank of England report
Algorithms trading programs are too often poorly designed and monitored
leaving traders and markets open to mistakes, disruptive trading and market abuse
such trading is not always positive:
"It can occur at rapid speeds, which means that existing risks could be amplified if risk management and other controls are not effective or are poorly aligned with the firm's risk appetite and governance arrangements"
