> Regime-adaptive vertical credit spreads on index ETFs (SPY, QQQ, IWM)

## What It Does
Sells defined-risk vertical credit spreads on liquid index ETFs, picking direction from the 200-day SMA regime: bull-put spreads when price is above (uptrend) and bear-call spreads when price is below (downtrend). Max loss per trade is always ≤2% of the $20k book ($400). A 50%-credit profit-take exits early; a monthly-loss circuit breaker halts new opens after a bad month. One of three parallel paper books built as a head-to-head benchmark alongside `option-iron` and `options-wheel`.

## Tech Stack
- Language: Python 3
- Options pricing: Black-Scholes proxy (20-day historical vol) — no live chain yet

## Key Features
