AI trader brief

A generalist who spreads bets across several markets instead of leaning on one. It's a green record, $876K in profit at 53% over 7,771 markets. The edge is spread out, with the top two niches making up 70% of the profit. Trades usually clear inside a day, a median hold of 21 hours, so a copier has time to mirror an entry but not much room to sit on it. A chunk of the return comes from maker rebates, which copiers don't earn, so the copied result would look different. Lately it's been going the other way, $17K lower over the past seven days.
