description: "$Nokia Oyj(NOK.US) Damn, I spotted a potential institutional accumulation signal, but it's the first time this has appeared, so I'm not sure how reliable it is. The signal shows that the max open interest (OI) for both calls and puts increased 2x compared to yesterday, spiking at the same strike price. The surging put is at $11 and the call at $12. Since I'm unsure about the validity of this signal, I'll hold off on selling and have no plans to add to my position."

- **jiafei纪律按系统执行 · 2026-08-19T06:53:29.000Z**: After backtesting, this signal looks a bit like a top signal. Help 🆘
  - **hg** (2026-08-19T07:06:00.000Z): Really? I'm a bit scared, still haven't broken even.
  - **jiafei纪律按系统执行** (2026-08-19T07:14:49.000Z): I'm not sure either, maybe the straddle option has no clear direction. But don't worry, optical communications will bounce back.
