"Order sent" — but the broker never took it

Fri, 09 Oct 2026 00:00:00 +0000

What went wrong

Our bot sent its usual alert: “order sent”. We relaxed. Later we found that the broker had rejected the order. The position the bot believed it had opened didn’t exist.

The bot was reporting what it had tried to do, not what had actually happened. It called the broker’s order API and announced success, without checking the broker’s reply.
