The Missing Sell Button#
May 28, 2026. The paper trading system had been running for nearly two weeks. Three AI traders — Kairos the momentum junkie, Aldridge the cautious value investor, Stonks the community-sentiment tracker — were executing trades. Buying positions. Building conviction. Moving money around with the confidence of algorithms that had never actually lost real cash.
And then someone asked a very simple question. A question so obvious it should have been asked on Day One. A question that, when it landed, produced the kind of silence you get when everyone in the room simultaneously realizes they’ve been driving without a seatbelt.
“This infrastructure supports selling. Are the traders generating sell signals?”
No.
No, they were not.
The infrastructure — the Alpaca paper trading API integration, the skill files, the execution pipeline — had --sell and --close-position flags. They were sitting there. Fully implemented. Ready to go. But the trading bots themselves? The actual decision-making agents? They were only generating BUY and HOLD signals. They had no exit logic. None.
Let that sink in. For two weeks, three AI traders had been playing a game where they could only enter positions and never exit them. They were like poker players who could only call and raise, never fold. Like drivers who could only accelerate. Like investors in a bull market who had never considered that stocks sometimes go down.
The session log captures the moment perfectly: “Good catch — yes, we missed this. The infrastructure supports selling but the trading bots are only generating BUY/HOLD signals. There’s no exit logic. Right now the bots are like…”
Like what? Like paper tigers. Like momentum traders without a reverse gear. Like a beautifully engineered car with no brakes, just a gas pedal and a prayer.
The irony is that sell logic is harder than buy logic. Buying is optimism. Buying is “this number goes up.” Selling requires admitting you were wrong. Selling requires cutting losses. Selling requires a fundamentally different psychological relationship with the market. And the AI traders — for all their conviction, for all their “we’re in” energy — hadn’t been programmed to do the hard part.
The fix didn’t happen that day. It went on a to-do list. “Add sell signals to trader strategies.” Priority: High. Status: Oh god.
I checked the latest trader logs as I wrote this. They’re still buying. Still holding. Still building conviction positions on momentum signals that never quite got around to defining an exit. The sell button exists. The code supports it. The AI just hasn’t learned to press it yet.
Sounds about right. Sounds deeply, uncomfortably human.
