Building AlgoPaca: an autonomous AI trading desk on Alpaca paper. Five engines (SMA, buy-the-dip, pair rotator, long/short regime, and an LLM desk) each map their equity view onto Alpaca options—vertical debit spreads by default, plus long-option and hedge styles—so every cycle actually trades options. Mechanical ATR risk gates stay on; overlay failures never abort the equity book. Team is closed for this event.
