Traders Agents

Overview

Layers 2–5 on the Mental Model. Four Trader agents (Warren Patience, George Bold, Ray Systematic, Cathie Crypto) share the floor timer. Each builds an OpenAI Agents SDK agent with MCP for accounts, push, and market, plus a nested Researcher tool. Env can assign different models per trader (USE_MANY_MODELS) or one shared gpt-4o-mini.

Behavior

• Scheduled peers (Parallelization). The floor wakes every trader on an interval; each decides trade or rebalance alone. See Building effective agents.
• Strategy as prompt. Persona and style live in trader_instructions; message is trade_message or rebalance_message based on do_trade, which flips after each run.
• Orchestrator-Worker. Nested Researcher has its own MCP belt (Brave, Fetch, memory/{name}.db); the trader places orders and push.
• Tools over MCP. Trader always attaches accounts, push, and market (local market_server.py or Polygon MCP).
• Max turns and traces. Runner.run with max_turns=30; LogTracer attributes rows per trader for the dashboard.

Tick flow

One scheduled tick for a single trader. Diagram key: ✦ AI agent · second line = Anthropic workflow · purple = actor · white = service.
