IRiskManager

IRiskManager defines an interface for validating whether a given order complies with system-defined risk constraints before it is submitted.

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

Purpose

• Enforce pre-trade risk checks such as size limits, leverage rules, or order throttling.

Responsibilities

Method	Description
allow()	Returns true if the order is permitted to proceed.

Notes

• Called by strategy or execution layer before submitting an order.
• Stateless implementations may rely solely on order parameters; stateful variants may track recent flow.
• Integrated into the engine via ISubsystem for unified startup and reset behavior.
