Jev 做交易决策、Opus 写交易台：19 天实盘复盘
Jev 用 Choice long/short/flat 和 Score 仓位给每笔交易下判断，代码算仓位与风控，19 天 291 笔净赚 2260 美元，8.2 万次决策花了 8.27 美元。
JEV CALLED EVERY TRADE, OPUS 5.5 BUILT THE DESK, AND $25,000 BECAME $27,260.60 IN NINETEEN DAYS Jev is TypeSafe's decision model. It doesn't generate text. It returns typed answers: Choice long / short / flat, Score size 0–1, each with a probability and a confidence. so the split was simple. Opus 5.5 wrote the desk and reads the journal every night. Jev makes every call. Code does all the maths, because Jev's own docs say keep arithmetic out of the model. trade 214, the one on the chart: - Jev: long ETH at 2,412, p .71, 84ms - Score .52 × a 10 ETH cap = 5.2 ETH, sized in code - notional $12,542, over $10k, so it waited 35s for my click - take-profit at 2,460: 48 × 5.2 = +$249.60 nineteen days: 291 trades, 163 green. $4,180 gross. Fees $1,212, funding $389, tokens $318.40. Net $2,260.60. 82,080 Jev decisions cost $8.27 in total. 37 orders waited for a human. the API key can trade. It cannot withdraw. the spider in the video walks every panel: it replays the trade candle by candle, presses all four approval gates, and ends on the line where buy-and-hold wins. next round I'm giving Jev a choppy month instead of a trending one. that's where the drawdown either earns its keep or doesn't, and the full desk goes up here when it's done. if you know someone who thinks an AI trading bot is free money, show them the honest panel first. Jev or just hold?
