On 10/14 RGTI fell to $12.12, leaving the 14.5P two days to expiry and deep in the money (Δ −0.98). Assignment meant 400 shares ≈ 60% of NLV plus negative cash — the accident line. At 10:03 ET, a single BAG order: bought back 14.5P×2 @ $2.34, sold 14.0P JAN 2027×2 @ $2.76 — net credit $84, old leg settled at −$390.74, obligation downgraded and pushed 93 days out. The cost, stated plainly: the new leg is still ~15% ITM with Δ −0.58, so assignment remains the base case. Includes the three-path comparison and the follow-up trigger lines.

On 10/12 NOK fell to $10.08 (−2.7%), compressing the time value of two covered calls — the 12C×5 sold on 9/18 shrank from $0.44 to $0.10, and the 12.5C×10 sold on 10/3 from $0.163 to $0.05. The pre-earnings exit window was planned for 10/15–21; the conditions arrived early. Two limit buy-backs at 09:53 and 11:47 ET on 10/12: +$270.13 total (broker realized P&L, incl. $9.49 fees). Last 20–30% of premium converted into cash — before the 10/22 earnings and 10/23 expiry.

October 8, US session — a sector-wide pullback knocked NOK down 4.5%, not one headline of its own; at 14:01 I bought JUN 2027 10C ×10 at $2.050 in four clicks. The next day NOK rebounded +3% and the new lot was up 12% in a day — but cash at $775, maintenance margin at 69.9% and LEAP concentration at ~70% had all crossed their lines. Under the risk rules the lot went back at $2.24: cash basis +$175.05, settlement basis −$330.72. A 24-hour round trip — entries are a gift from the tape; exits are a demand from discipline.

October 6, US Eastern — a big-up day for Nokia, and two clicks 32 minutes apart: at 11:17 the OCT 9 $10 puts ×5 came back at $0.04 ($0.263 → $0.04, net banked +$107.94); at 11:49 the NOV 20 $13 calls ×5 went out at $0.32 (net $156.20 collected). One old lease redeemed at a 15% residual, one new lease written at the 13 strike with a 21% cushion — and from today, all 20 LEAPs are leased, 20/20. This entry covers why a pure seller closes before opening, the pricing on both legs, and what the board looks like now.

October 1, US session — two buyback clicks. 10:39 AM ET: NOK Oct 2 $10 puts ×5 back at $0.05; 11:34: RGTI Oct 9 $18 calls ×2 back at $0.10. Combined net banked: +$129.78. One leg came from the September 22 three-tier put sale; the other was the covered call sitting on the RGTI shares. This entry covers the full life of each leg, the $48.85 price of leaving early, and what remains on the board.

A Xiaohongshu post claimed friends had quit their jobs on stable options income. I did not laugh at it — I gathered 40 years of global evidence, 100 comments, and my own 143 real options trades, and put the question on trial. The verdict is not yes or no. It is three switches.

On September 28 (US Eastern), 11:15 — 23:15 Beijing — I bought back the last 10 contracts of my NOK Oct 2 $11 call. The $0.03 limit never got a seller; the fill came at $0.04, $43.20 all-in including fees, banking +$114.80. This entry covers why "clearing an obligation" is the only right move in a RED account, what the gap between $0.03 and $0.04 is really about, and what is left on the Nokia board.

On September 22 (US Eastern), mid-session — just past midnight Beijing time — I sold 15 NOK puts across three expiries: 10P OCT 2, 10P OCT 9 and 9.5P OCT 23, netting $393.50 in premium. This entry covers why I sold, what the assignment ledger looks like, the margin bill (30.4% to 63.4%), and why this position got a management calendar from day one.

In the early hours of September 22 Beijing time (midday September 21 US time), the last 2,300 TRON shares were sold at $1.542 — closing the books on an inventory battle that began in July 2025. The same night, both NOK put positions were closed (settled +$95.47). Account leverage dropped to 0.82x and cash swung from -$81 to +$3,368. With +$693.86 of stock-lending fees earned over the holding period, the fourteen-month net narrows to about -$819. This was not an ordinary stop-loss — it was a system upgrade: except for 200 RGTI shares, all capital now goes to options.
