Brad Toonie — USD/CAD Signal Desk (Python)

Brad Toonie is the USD/CAD ("the Loonie") 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 Brad Toonie desk makes.

What it does

Brad trades Canada's oil-sensitive dollar with a selective RSI(2) reversion approach and a tighter threshold than the other FX desks — so he only fires on more pronounced extremes, fewer but cleaner setups, holding about two hours. Each run reads real USD/CAD 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

• brad_toonie_cad.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.
