Performance & Stability
        
        What Happens If I Lose My Connection during a Smart Trading Order?
        
         
        
        
          
        
        
      
        
     
        
        A lost connection triggers a system-state query; the order's fate depends on whether its logic is client-side or server-side.
        
        How Can a Trading System Ensure State Consistency between Its Internal Records and Exchange-Reported Fills?
        
         
        
        
          
        
        
      
        
     
        
        A trading system ensures state consistency through a layered defense of idempotent architecture, protocol-level validation, and continuous, multi-frequency reconciliation against exchange data.
        
        How Does a Drop Copy Feed Differ from a Standard Execution Feed from a Broker?
        
         
        
        
          
        
        
      
        
     
        
        A standard execution feed is an interactive channel for placing trades; a drop copy is a read-only mirror for monitoring them.
        
        How Has the Mandate for Central Clearing Affected the Importance of the Post-Clearing Drop Copy?
        
         
        
        
          
        
        
      
        
     
        
        Central clearing mandates transformed the drop copy from a passive record into a critical, real-time data feed for risk and operational control.
        
        How Can a Firm Leverage Exchange Drop Copy Ports to Enhance Its Own Risk Management System?
        
         
        
        
          
        
        
      
        
     
        
        A firm leverages exchange drop copy ports to build an independent, real-time surveillance system for proactive risk control.
        
        How Does a Drop Copy Feed Help in Complying with Market Access Rules like SEC Rule 15c3-5?
        
         
        
        
          
        
        
      
        
     
        
        A drop copy feed provides the immutable, real-time data necessary to power and validate the risk controls mandated by SEC Rule 15c3-5.
        
        How Do Exchange-Provided Risk Tools Interact with a Broker-Dealer’s Own Control Systems?
        
         
        
        
          
        
        
      
        
     
        
        The interaction is a layered defense: the broker-dealer's granular controls act first, with exchange tools as a systemic backstop.
