Risk Manager

The IRiskManager interface defines the logic responsible for enforcing trading risk limits before order submission.

Purpose

To act as a gatekeeper for outbound orders, ensuring compliance with capital, exposure, and custom risk rules.

Interface Definition

class IRiskManager : public ISubsystem {
public:
  virtual ~IRiskManager() = default;
  virtual bool allow(const Order &order) const = 0;
};

Responsibilities

• allow(...): evaluates the order and returns true if it's safe to proceed
• Integrated into the system lifecycle via ISubsystem

Use Cases

• Capital-based order blocking
• Exposure control per symbol or globally
• Custom constraints (e.g., time-of-day, user-defined logic)

Notes

• Typically used in conjunction with IOrderExecutor
• Stateless or stateful implementations depending on enforcement logic
