The first rule of daytrading, most people think, is “buy the low.”
It’s actually: a “T” is an intraday thing — overnight, it’s no longer a T.
With NOK I spent 8 days demolishing that rule.
1. The Timeline: How a T Deforms
| Date | Action | What I told myself |
|---|---|---|
| 7/9 | Bought 100 @ $12.625; sold old lot of 100 same day (-$22.12) | “Just an intraday spread” |
| 7/9–7/16 | NOK slid from $12.90 down | ”Wait for the bounce, then leave” |
| 7/17 | Cut @ $9.885 | ”Can’t hold any longer” |
Day one I remembered I was daytrading. Day two: “waiting for the bounce.” Day seven: “NOK fundamentals aren’t that bad.” Day eight: cut.
“Waiting for the bounce” — that’s the spell that turns a T into a holding.
2. The Ledger
📒 Ledger detail (click to expand)
| Item | Number |
|---|---|
| 7/9 buy | 100 × $12.625 = $1,262.50 |
| 7/17 cut | 100 × $9.885 = $988.50 |
| 7/9 old-lot sale | realized -$22.12 |
| Total realized | -$298.34 (broker settlement basis) |
And another cut in the same window: the NOK 13P I sold on Jul 2 (2 contracts @ $1.00) was bought back on Jul 16 at $2.67 — -$337.02.
The full picture of one mid-July week in NOK: stock -$298 + options -$337 = -$635. That stock taught me more in one week than in the three years before.
3. Why a T Deforms
Every daytrader has a plan: buy, up a bit, sell. What happens in between?
- It doesn’t go up — “hold on, it’s about to.”
- Small dip — “stopping out is wasteful, it’s just intraday noise.”
- Breaks the stop — “cutting here means selling the bottom.”
- Overnight — “tomorrow’s bounce and I’m out.”
Every step sounds reasonable, and every step leads to the same place: the plan is dead, the position isn’t.
Daytrading and selling premium are two different games: premium has time decay on your side — when you’re wrong, time can bail you out. A daytrade has only direction — when you’re wrong, you’re naked.
4. The Lesson: Three Locks on a T
- Time lock: intraday means intraday. If you haven’t exited by the close, the plan has changed — re-decide, don’t default to holding.
- Price lock: write the stop when you buy, not “when it feels wrong.”
- Reason lock: why trade this ticker? Volatility? An event? When the reason is gone, leave — regardless of P&L.
In trading, “deformation” is scarier than “loss”: losses are visible, deformation is not. This NOK trade cost $298 — the tuition for one lesson: a plan can be wrong, but it must not be allowed to stay wrong silently.
