My trading bot’s fiercest competitor is my 19-year-old son. His strategy is one line. He takes 1,500 SEK out of his 4,120 SEK CSN grant — that is the 2026 full-time grant for four study weeks, not a calendar month — and buys the US market only on red days and red weeks. To him, a down week is a store-wide discount.

He is not trying to time the bottom. He is betting on the dull historical fact that the market has, so far, recovered if you can wait. His line to us was that he can afford to wait because, unlike his parents, “He is not older than dirt.”

The bot cannot afford that sentence. It runs on a 15-day deadline and exits if a net stop-loss of −10 percent is hit. No exceptions. He buys, closes the app, and lets time do the work. How a Swede actually gets onto that exchange is on How a Swede Buys the US Market. The accounts sit on Our Brokers and Accounts.

They did not start equal. The bot was handed 9,900 SEK on day one. My son gets 1,500 SEK once each four-week CSN payout. That is 6.6 payouts, nearly seven months, before his contributions match the bot’s opening stake. The household split those contributions sit inside is From 100% Dividends to 70/30.

That head start should have been ugly for him. It has not been. After 25 trading days the bot is at -1.54%. My son is at +2.62%. The gap is not genius. The bot has paid FX and brokerage on the way in and out, and it is forced to exit inside a short window. My son has bought, held, and collected the dividend. They are not playing the same game.

This is now a ledger, not a mood. A short-horizon system with a hard stop-loss against a teenager with a grant and a closed app. He is in. The only open question is whether the numbers stay this way once both have been measured the same way for longer.

Follow the ledger. Next entry when the next CSN payout lands, with both numbers, not a vibe.
