v2.3.0b5

What's New

underlying_price is now optional

• csv_data() no longer requires an underlying_price column — only underlying_symbol, option_type, expiration, quote_date, strike, bid, ask, and delta are needed
• TA-based signals (RSI, Bollinger, MACD, etc.) now require a close column in stock data rather than falling back to underlying_price
• apply_signal() auto-merges Yahoo Finance stock prices when the options data lacks a price column, so IV rank and other price-based signals work out of the box

Standalone data CLI (optopsy-data)

• New optopsy-data CLI for downloading and caching historical options data
• optopsy-data symbols command to list available symbols [EODHD only]
• optopsy-data download SPY -s flag to download stock prices alongside options
• optopsy-data cache subcommand for cache management (size, clear)

Revamped sample files

• Replaced 12 repetitive examples with 5 progressive samples covering the full API: basic strategies, signal composition, simulation with risk management, portfolio backtesting, and strategy comparison

Documentation

• New MkDocs documentation site with auto-deploy on push
• Updated docs to reflect the optional underlying_price architecture
