MANDATE — The Stateful Multi-Agent Trading Desk

MANDATE is an autonomous, stateful multi-agent trading desk for Alpaca paper markets that operates continuously across market and off-market hours. In the background, a persistent research process collects attributable news, market events, corporate actions, movers, and IPO activity, organizing them into an evolving graph of connected evidence. Instead of treating each trading cycle as an isolated prompt, MANDATE carries this accumulated context forward. New information is linked to events, companies, hypotheses, and prior research, allowing agents to reason over fresh market signals together with the continuously evolving news graph. A main trader combines quantitative signals with context retrieved from this graph to produce an evidence-bound trading plan. Independent market, risk, and execution agents challenge each hypothesis before any action reaches the broker, creating a true multi-agent decision process rather than a single model approving its own trades. LLMs never receive direct broker write access. A deterministic execution boundary revalidates market state, portfolio constraints, liquidity, exposure, and order parameters before submission. Invalid output, stale evidence, unavailable critics, or breached limits resolve to PARK or HOLD. MANDATE supports equities and defined-risk options strategies, including long premium and debit spreads. Its live operator console exposes hypotheses, background research, agent activity, tool calls, evidence dependencies, positions, exit policies, and P&L. MANDATE is not a trading chatbot that wakes up when prompted, but a persistent multi-agent system whose understanding of the market continuously evolves and informs future decisions.
