Position Manager Interface

The IPositionManager interface provides access to position information per symbol.
It is typically implemented by a component that tracks fills and updates internal position state.

Purpose

To allow strategies, trackers, or execution components to query current exposure levels per trading symbol.

Interface Definition

class IPositionManager {
public:
  virtual ~IPositionManager() = default;

  virtual double getPosition(SymbolId symbol) const = 0;
};

Responsibilities

• getPosition(...): returns the current net position for the specified symbol
• Underlying implementation must keep this data consistent and accurate

Use Cases

• Risk checks before submitting new orders
• Displaying strategy exposure
• Calculating PnL or exposure-weighted metrics

Notes

• This interface only provides read access
• Actual position tracking is done by components like PositionManager
