description: "Paper account day tripMade two trades at the open, shorted Netflix, went long on NVIDIA's "favorite son".And at the open, the movements of Netflix and NVIDIA's "favorite son" were consistent with my expectations. Netflix indeed plummeted, but because I wasn't fast enough to grab shares, I only made 20 points. I chose to keep one option contract, but that contract also has a cost, over 100 bucks. As a result, that option is now worthless.On the NVIDIA "favorite son" side, I was a bit faster with my hands, but still didn't hold on. After it rose 20 points, I chose to withdraw the principal and let the profits run. But later, I couldn't control my hands. Seeing it pull back to 82 bucks, I thought it would break the previous high of 84.8, so I bought 5 option contracts. Huge loss, now both the principal and profits are locked in.The paper account once doubled, could have tripled actually, but because I was busy with my real account, forgot to take profits in time, and later stubbornly shorted Netflix, causing the paper account's principal to almost halve.$Netflix(NFLX.US)$Invesco QQQ Trust(QQQ.US)$Coreweave(CRWV.US)"

- **youngerliu · 2026-02-28T08:11:29.000Z**: Do you need to write so much drama for a simulated trading account?
- **顾神与chatgtp · 2026-02-28T05:46:26.000Z · 👍 1**: Directional judgment was actually not bad.Short Netflix — it did indeed plummet at the open.Long "NVIDIA's godson" (most likely an AI chain company strongly related to NVIDIA) — the price movement also met expectations.In other words:Directional judgment ≠ The main problem.This point is cruc
- **xiaomayi666 · 2026-02-28T03:11:54.000Z**: In real trading, I lost 98 out of 100 times. I introduced a simulation account, playing the simulation based on my previous real trades. I then do the opposite in real trading compared to the simulation. Wouldn't that instantly raise the win rate to 98%?
- **路边的韭菜 · 2026-02-28T02:55:08.000Z · 👍 1**: Didn't expect Gu Shen's simulated trading account to come so fast 😅
- **郑浩然车检 · 2026-02-28T02:48:17.000Z**: Am I also desperate?

- **SK117 · 2026-02-28T00:28:21.000Z · 👍 6**: Kai Si, from now on, I'll call you the Simulated Account Expiring Options Prince.
  - **Lu Lu** (2026-02-28T02:40:44.000Z): No, virtual trading doesn't give you the thrill, anyway, there's unlimited capital to top it up.
  - **SK117** (2026-02-28T02:42:10.000Z): Kai Si can only go to Macau to collect the 'duck money' and top up his margin. He just doesn't get it. How can he collect the 'duck money' without going to Macau?
  - **Lu Lu** (2026-02-28T02:57:27.000Z): This guy is quietly making a fortune now. Isn't it great to earn $3200 in one go in Macau?
- **强者恒强 · 2026-02-28T00:19:07.000Z**: Will you still get money after the simulated account is cleared?

- **北极星baby · 2026-02-27T19:06:32.000Z · 👍 1**: Just trade with a simulated account, watching the account balance is also nerve-wracking.
- **美股主升浪 · 2026-02-27T18:38:51.000Z**: You know how to do reverse operations
- **樂在骑中 · 2026-02-27T18:31:28.000Z · 👍 1**: When simulating, the mindset is completely different, so there's no point in playing.
- **fries fund · 2026-02-27T18:23:40.000Z**: God is God
- **APTAPT · 2026-02-27T18:11:15.000Z · 👍 22**: From now on, I'll start playing with a simulated account. This means unlimited ammo.
