# QQQ Expiring Options April 23 Quantitative Trading System Review

### I. Profit Situation

Last night, a total of 74 trades were made, profit: $18,148 $Invesco QQQ Trust(QQQ.US) loss: $7,024, net profit: $11,124.

Because in the first half of the night, my position opening setting was 10 contracts/time, and in the second half, I changed it to 5%-10% of the total capital to open positions. The win rate was higher in the first half, otherwise last night's profit would have been even higher.

### II. Problems Encountered

The dynamic profit-taking feature had a bug. My dynamic profit-taking setting was: close half the position when reaching 100% profit, then let the remaining position continue, and close the entire position when it retraces 30% from the peak profit.

Last night, there was one order where it was closed entirely in two batches without capturing the maximum profit.

### III. Problem Solving

When a problem is discovered, the first thing to do is to let the AI check and solve it itself.

Actually, I solve many bugs every day, so the system improves and parameters are adjusted daily.

When the system is running normally, I use MiniMax2.7 which is terrible but cheaper. For modifying programs and code, I use Xiaomi MIMO-V2.5 PRO which is very good and solves the bugs generated by MiniMax every time.

- **坚决不入坑 · 2026-04-29T17:12:02.000Z**: Could you please advise on how to set up simulated trading?
- **Luck_Giao · 2026-04-28T17:21:28.000Z**: Teacher, do you use a skill to let the AI run, or do you use AI-assisted code and throw the script to the server to run?
  - **热血青年** (2026-04-29T07:33:14.000Z): AI writes scripts to run on its own computer, AI reviews and optimizes
- **闲庭信步纳斯达 · 2026-04-27T10:31:58.000Z**: May I ask if you plan to operate a quantitative live trading account on Longbridge or switch to another brokerage firm after your backtesting stabilizes?
  - **热血青年** (2026-04-27T11:32:56.000Z): Definitely staying on Longbridge, because the system is built on Longbridge
  - **闲庭信步纳斯达** (2026-04-27T11:35:34.000Z): So I see you seem to have quite a lot of funds, teacher. Aren't you worried about CRS back taxes? I basically don't dare to keep much money in Longbridge anymore, it's mostly in IB.
  - **闲庭信步纳斯达** (2026-04-27T11:38:13.000Z): I thought you were mainly backtesting strategies on Longbridge, after all, Longbridge's API is free and the Chinese documentation is convenient.
- **忌贪忌躁忌赌落袋为安 · 2026-04-26T07:20:45.000Z**: May I ask, during the Longbridge API test, it was found that only K-line data from April 2024 to the present can be downloaded. Why can you download data from January?
- **反复分析 · 2026-04-26T03:51:37.000Z**: Learning something new, may I ask why the exhaustion reversal is limited to once per day? Is it the optimal result from backtesting?
  - **热血青年** (2026-04-26T04:00:07.000Z): This is just an example, you can modify it based on your own trading situation.
- **耄耋的交易員 · 2026-04-24T14:06:59.000Z**: Bro, is there a script missing on GitHub? 🤔
  - **热血青年** (2026-04-25T09:29:08.000Z): Everyone's configuration environment is different; some documents are better when you generate scripts yourself using AI.
- **宇宙战舰大和号 · 2026-04-24T11:40:46.000Z**: Boss, I'm using Tencent Cloud's Hermes. Why can't the AI they provide access external links? How do I fix this?
  - **热血青年** (2026-04-24T12:04:52.000Z): Cloud servers cannot access servers and websites outside of mainland China. You can download and then upload to Tencent Cloud yourself.
  - **宇宙战舰大和号** (2026-04-24T12:47:15.000Z): Then AI won't be able to check the market through Longbridge either.
  - **卖飞的小韭菜** (2026-04-29T13:10:48.000Z): Buying servers from other regions, I bought a Korean one.
