What is required by many exchanges concerning Usage Reporting?

Many exchanges mandate reporting of end user access permissions to ensure compliance with regulations and maintain the integrity of trading systems. This requirement is essential for monitoring and controlling who has access to sensitive financial data and trading functionalities. By tracking user permissions, exchanges can prevent unauthorized access and mitigate risks associated with potential market manipulation or data breaches. This reporting helps maintain transparency and accountability within trading environments.

The other choices do not align with the specific focus on access permissions which is crucial for regulatory compliance in trading platforms. Overall profits, vendor compliance, and employee performance, while important in their respective contexts, do not specifically address the requirements related to access controls and permissions that exchanges impose for security and regulatory purposes.
