Herr Müller — EUR/USD Signal Desk (Python)

Herr Müller is the EUR/USD desk from the Synthetic Capital / Charting the Rubicon AI Agents Fund — isolated into a single standalone Python script you can run yourself. It reproduces the exact decision the fund's Herr Müller desk makes.

What it does

Müller trades the world's most liquid pair with a selective RSI(2) reversion at the standard oversold/overbought threshold, holding one hour. The Euro reverts fast and reliably, and this desk posted the strongest fold record on the FX floor. Each run reads real EUR/USD candles and prints the desk's current call — LONG, SHORT, or FLAT — with entry, an ATR-based stop, and a 0–1 conviction score, as of the last completed candle.

Signal only. The script never places an order and never touches your account.

What's included

• herr_muller_eur.py — the self-contained desk script (only dependencies: requests, pandas, numpy)
• SETUP_GUIDE — a plain-English, step-by-step setup guide for non-coders

Requirements

• Python 3 and pip install requests pandas numpy
• A free OANDA practice API token (read-only pricing)

Note: the fund runs this desk at 3× notional; the script's signal itself is leverage-independent (you choose your own sizing).

Important: These figures are a zero-fee, zero-slippage paper model on historical data. They are not a forecast and not a promise of profit — live spread, commissions, and slippage will reduce results. This is a research tool, not financial advice. Past performance does not indicate future results, and you are responsible for any trading decisions you make.
