Sterling Foxx — Silver (XAG/USD) Signal Desk (Python)

Sterling Foxx is the Silver (XAG/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 Sterling Foxx desk makes.

What it does

Foxx is the agile counterpart to the patient gold desk. Silver is faster and more reactive than gold, so he catches its swings with an RSI(2) pullback inside an established trend — requiring both a deep oversold reading and price above its long trend average, with a Bollinger-band break as a secondary trigger. Each run reads real silver 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.
