AI trader brief

This looks less like a bettor and more like a market maker, quoting both sides for the spread. It's a green record, $850K in profit at 48% over 6,772 markets. The tell is entry price: P50 80 carry the record while Lt20 give money back. The book's busiest across European hours. Worth a caveat: much of this volume is maker flow, so a copier's entries won't match theirs. This past week looks about average for them, with no real shift either way.

Generated nightly from verified chain data. Never speculative.
