This archive aggregates CTEC's daily end-of-day options snapshots into monthly summaries, spanning 2021-06 through 2026-07. Each month rolls up the underlying snapshot archive, which provides continuous end-of-day coverage from 2007 to present: implied-volatility levels, IV rank, and the put/call ratio are time-averaged across the month; total call and put volume are summed; and dealer positioning (net gamma and delta exposure) and the max-pain strike are taken at the month's final trading day. The result is a long-horizon view of how CTEC option pricing, volatility regime, and dealer hedging pressure evolved month over month, useful for backtesting strategy assumptions and for studying volatility-regime shifts around earnings and macro events. The most recent aggregated month (2026-07) shows an average ATM implied volatility near 80.3%, a month-end max-pain strike around $51.00, an average put/call ratio of 0.00.
