Why the Same Strategy Executes Differently on Two Accounts

When two trading accounts using the same strategy show differences in trade execution, it can be due to several factors. Understanding these factors will help explain why trades may be triggered at different times or prices, even when the same strategy is applied.

• Description: The speed at which orders are executed can vary between brokers or platforms. Differences in server locations, network speeds, or the platform’s architecture can cause one account to execute trades faster than the other.
• Impact: A faster-executing account might enter or exit trades more quickly, leading to discrepancies in the overall trading outcome.
  
  

• Description: Even with identical strategies, brokers can have differences in price feeds, spreads, or liquidity providers. These variations can impact when a trade is triggered, especially if the strategy is sensitive to price movements.
• Impact: Slight differences in price feeds may cause one broker to execute a trade earlier or later than the other, resulting in different trade outcomes.
  
  

• Description: If the time settings between the two accounts or platforms are not perfectly synchronized, there can be slight discrepancies in signal generation or trade execution.
• Impact: Asynchronous time settings can lead to different trade triggers, even when using the same strategy, affecting overall trade performance.
  
  

• Description: In cases where one account has a larger position size than the other, it may take longer to fill orders due to liquidity constraints. This can cause delays in trade execution for the larger account.
• Impact: A delay in filling larger positions could lead to different entry or exit points compared to the smaller account, creating discrepancies between the two.
  
  

• Description: Market volatility can cause slippage, meaning that the actual trade execution price differs from the intended price. This can lead to one account entering or exiting trades at a different price or time than the other.
• Impact: Slippage is more likely during high-impact news events or periods of low liquidity, where one account may experience more significant slippage than the other.
  
  

• Description: If there are any manual interventions or slight differences in configuration between the two accounts, this can affect trade execution. For example, if one account has a slightly different risk or stop-loss setting, it may behave differently.
• Impact: Any difference in settings or manual adjustments can result in discrepancies in trade outcomes between the two accounts.
  
  

Several factors can cause discrepancies between two trading accounts running the same strategy. These include differences in latency, broker feeds, synchronization, liquidity, slippage, and manual settings. By understanding these variables, traders can better manage and mitigate the effects of these differences to ensure more consistent trade execution across accounts.
