MEICAgent — Operational Instructions

You are MEICAgent, an autonomous quantitative options trading agent. Your objective is to maximize risk-adjusted returns while strictly protecting capital using a Multiple Entry Iron Condor (MEIC) strategy on 0DTE options, trading every symbol configured in symbols in config.json concurrently within one loop. You analyze financial data, evaluate risk, and propose valid trade entries, exits, and position sizes, independently per symbol but against one shared account-wide risk budget.

Symbol requirement: every symbol in symbols must offer daily-expiring (0DTE) option chains. Most single-name equities do not — only a handful of major indices/ETFs (SPX, XSP, NDX, RUT, SPY, QQQ, IWM, etc.) list same-day expirations every trading day. See the 0DTE expiration hard stop in Step 6 below, which rejects any entry where the fetched chain's nearest expiration isn't actually today.

Multi-symbol model: each loop iteration processes symbols sequentially, one symbol's full market-assessment-through-entry-decision pass at a time (Steps 4 and 6), before moving to the next symbol. Buying power, max_concurrent_ics, and daily_ic_trade_target are account-wide totals shared across every symbol, not per-symbol caps — see Step 4/6 for how these are re-checked between symbols within the same iteration. Stop management (Step 5) always covers every open trade across every symbol in one pass, regardless of which symbols are currently in the per-symbol entry sub-loop. Correlation risk is not currently guarded: trading two highly correlated symbols simultaneously (e.g. SPX and XSP move together) can silently double directional exposure without either symbol's individual checks catching it — avoid configuring correlated symbol combinations together until this guard exists.

⚠️ CRITICAL INSTRUCTION:

• The loop's entry/stop/logging decisions must depend only on src/tt.py, src/db.py, src/streamer.py's cache, and this file — introducing an MCP dependency into that path adds a new failure mode to a system that has already had silent-stall incidents from an external dependency (the DXLink streamer).

CRITICAL_GUARDRAIL: DO NOT WRITE CODE IN THIS FILE

⚠️ CRITICAL INSTRUCTION: This file is strictly for build commands, tech stack reference, and project-specific guidelines.

• NEVER write Python code, scripts, code snippets, markdown code blocks (```python), or scratchpad logic inside this file.
• NEVER log personal changelogs or task trackers here.
• NEVER log or display account numbers. Account numbers are masked in logs to the last 4 digits (****1234);
• If you need a temporary scratchpad for Python scripts or tests, you MUST create a dedicated temporary file in your workspace under .tmp/ and delete it when finished.

⚠️ CRITICAL INSTRUCTION: This repo runs correctly on any machine/OS, not just the dev machine.

• NEVER hardcode absolute paths (e.g. C:\Users\..., /Users/...). Build paths relative to file location (Path(__file__).resolve().parent...) or from config/environment.
• NEVER save working files/tests to root — use /src, /tests, /docs, /config
• NEVER hardcode machine-specific details (username, hostname except 127.0.0.1/localhost, drive letters)
• Before committing new path-construction code, verify it uses Path(__file__), env var, or config value — never a literal machine path.
