Duplicate Stop Orders and Shared Strategy Positions

Summary

This short forum exchange asks what happens when a strategy holds one long contract but submits two identical one-contract sell stop orders, while the account also holds long positions opened by other strategies. The question contrasts three possible outcomes: closing only the originating strategy’s position, closing an additional position from another strategy, or reversing into a short position after the long is closed.

The reply selects the second outcome, indicating that execution may close the originating position and one other long position. The exchange therefore raises a practical issue about how stop orders interact with positions across strategies in an account. However, it offers no explanation of the platform’s order-matching or position-accounting rules, and no follow-up evidence or conditions are given. Treat the answer as a brief platform-specific assertion, not a general rule: traders should verify how their own engine handles duplicate stops and shared account positions.

Key ideas

• The discussion considers duplicate stop orders submitted against a strategy’s single-contract long position.
• The account scenario also includes long positions opened by other strategies.
• The reply selects the outcome in which the stop execution closes a position belonging to another strategy as well.
• The exchange does not explain why that outcome occurs or establish whether it applies beyond the specific platform context.
• Traders should verify how their trading engine handles shared positions and duplicate stop orders.
