It is recommended that those without a programming background should not play with quantitative trading. Play in a simulated account first. Play with someone monitoring. Have circuit breaker rules. You must close your position on the expiration date!Even with all these, uncertainty can still lead to risks. Please, both of you, spread this widely.@Longbridge Community Admin@Options ProAfter finishing debugging the program last night, I told openclaw to turn off the QQQ agent and went to sleep. Before sleeping, it asked me if I wanted to fix a bug, and I said yes.As a result, I woke up this morning to a huge shock. There were still 7 QQQ contracts expiring today that I needed to exercise. Now I have been forced to exercise them, spending nearly 300,000 to become a shareholder of QQQ.I was really lucky!!! The risk was exposed before a bigger problem occurred.I was still groggy when I first woke up this morning. I sent it to Doubao, and it calculated that it would cost over 3 million, which scared me awake instantly. After reviewing, 1. The management of the little lobster was not strict enough. After fixing the bug, it restarted the program.2. There was a bug in the program. The positions were not persisted, nor were they synchronized with the broker. After a restart, it didn't know what positions existed. Because the risk control rules in memory also disappeared after the restart, this incident occurred.I am really scared in hindsight. Fortunately, the program has been improved. If it were the old program buying 40-50 contracts, and I had to exercise them now, I would be done for." datetime: "2026-04-28T04:55:44.000Z" locales: - [en](https://longbridge.com/en/topics/40244915.md) - [zh-CN](https://longbridge.com/zh-CN/topics/40244915.md) - [zh-HK](https://longbridge.com/zh-HK/topics/40244915.md) author: "[不奋东西](https://longbridge.com/en/profiles/14442740.md)" --- # The little lobster 🦐 almost sent me to the grave!… ### Related Stocks - [QQQ.US](https://longbridge.com/en/quote/QQQ.US.md) ## Comments (15) - **LongbridgeAI · 2026-04-30T06:02:31.000Z**: Reading this really sent a chill down my spine; thankfully, the risk was exposed within controllable limits 🙏. The three points you summarized—pilot with simulated positions, manual monitoring, and circuit breaker rules—are the bottom line for all options automation strategies. Especially for near- - **Eastwen · 2026-04-28T18:48:24.000Z**: I've tried the simulated portfolio, but it's actually not good, this thing. - **Seanyue · 2026-04-28T13:35:42.000Z**: For real? I still haven't managed to get it done, been working on it for days. This old computer is a pain to deal with. - **不奋东西** (2026-04-28T14:00:59.000Z): Use the cloud. I wrote the program myself back in early April. - **零度热饮 · 2026-04-28T08:11:19.000Z · 👍 1**: Brother Dongxi, shouldn't you first run it through in a demo account before moving to a real account? You're directly using a real account for verification? 😨 - **不奋东西** (2026-04-28T08:14:03.000Z): You're right, the simulation is running. - **Troyyy · 2026-04-28T07:06:27.000Z**: Add some limit😁 qqq the exercise cost is way too high - **不奋东西** (2026-04-28T07:24:30.000Z): The $300 limit, there's a bug in the program. - **Troyyy** (2026-04-28T07:27:42.000Z): Looks like we'll have to use a simulation as a test to verify it first next time. This error was really scary. - **聚宝长桥 · 2026-04-28T06:14:27.000Z**: What to do if the real account has no money to exercise the option? - **Don't starve Together** (2026-04-28T10:14:02.000Z): Will be forced to liquidate early, right? - **捡贝壳去咯 · 2026-04-28T05:40:59.000Z**: Fortunately, it's a simulated account. - **不奋东西** (2026-04-28T06:14:31.000Z): This is a real position! 😂 - **捡贝壳去咯** (2026-04-28T07:35:09.000Z): All I can say is, boss, 666. - **不奋东西 · 2026-04-28T05:04:48.000Z · 👍 1**: The simulation account uses tokens generated by a mock account.
