- **SUKI · 2026-04-29T02:01:41.000Z · 👍 2**: Simulation is boring. Options can be traded freely, but in real trading, you can't sell them at all.
  - **Z兄交易笔记** (2026-04-29T03:59:58.000Z): Awesome bro
- **自信的我 · 2026-04-28T16:41:14.000Z · 👍 2**: Why cancel the account
  - **Z兄交易笔记** (2026-04-28T16:47:36.000Z): Perfectly concluded, focusing on live trading now.
- **小旋风2025 · 2026-04-28T15:12:12.000Z · 👍 2**: I now feel like I'm playing with a simulated account using real money. Because I'm only playing with my pocket money.
  - **Z兄交易笔记** (2026-04-28T15:13:16.000Z): This is the truth. Manage your idle money.
  - **小旋风2025** (2026-04-28T15:14:44.000Z): It's not even called financial management anymore. It's lottery money 🤣🤣🤣
  - **Z兄交易笔记** (2026-04-28T15:15:54.000Z): I envy you, man.
- **Jack deng · 2026-04-28T15:10:31.000Z · 👍 1**: There's no feeling of real money in simulated trading, and there's no economic pressure anyway.
  - **Z兄交易笔记** (2026-04-28T15:13:28.000Z): Yes. For speculative short-term trading, mindset is very important.
  - **Jack deng** (2026-04-28T15:16:10.000Z): Otherwise, if you have spare money, buy good companies for the long term and hold them. That's not like doing one or two short-term trades a day and then pulling out; most people can't handle that.
