Access control in an algo trading system is used to decide who can access the platform and what actions they are allowed to perform. This helps protect trading strategies, user data, and system operations.

When you develop an algo trading software, access control is usually set up using user login systems, where only authorized users can enter the platform. After login, different roles are assigned, so each user can only access certain features. For example, some users may only view data, while others can manage trades or system settings.

There are also permission settings that limit access to specific actions such as editing strategies or executing trades. In addition, the system can track user activity to monitor what actions are being performed.

This way, the platform keeps control over who can do what, and reduces the risk of unauthorized access or misuse.
