description: "$Tesla(TSLA.US) is back to playing end-of-day high-frequency trading. With only 100k principal, the rest of the money has been deployed but not yet settled. If this 100k is wiped out, I'll deposit another 100k. If that's also lost, I'll conclude this strategy doesn't work, effectively saying goodbye to options, US stocks, and HK stocks. I'll wait until prices are extremely low to bottom-fish, buying regular shares without leverage for value investing."

- **xiaoyang炒股养家 · 2026-07-29T17:55:22.000Z**: It's actually possible to sell TSL options with 100k, which is pretty good; sellers have a natural advantage.
  - **石头老弟** (2026-07-29T17:57:36.000Z): It seems you can sell for around 50k, it's just that the volume is low,
  - **xiaoyang炒股养家** (2026-07-29T17:59:27.000Z): Watch out for risks
- **还是买纳指吧 · 2026-07-29T17:53:45.000Z**: Brother Shitou, roughly how much are your option fees at Longbridge per month?
  - **石头老弟** (2026-07-29T17:55:06.000Z): It mainly depends on how many contracts were traded. In total, my option premiums over more than a year should be around $20,000.

- **xiaoyang炒股养家 · 2026-07-29T17:46:35.000Z**: Is it 100k RMB? It looks like you're short selling options at the end.
  - **石头老弟** (2026-07-29T17:53:21.000Z): It's in RMB. My strategy this time is to sell puts and calls with a 70% position, and buy calls and puts with a 30% position. So there will be more short option positions, with a stop-loss of 25% and
