OPEN-SOURCE SCRIPT
Opex + Triple Witching (Julio)

Triple Witching occurs on the third Friday of March, June, September, and December.Triple Witching occurs on the third Friday of March, June, September, and December. It's when three types of derivatives expire simultaneously: stock index futures, stock index options, and stock options. This causes elevated volume and volatility as traders roll or close positions.
OPEX (Options Expiration) is every other third Friday of the month — the ones that are NOT Triple Witching. These are standard monthly options expirations and also tend to see increased volatility and pinning behavior around key strikes as market makers hedge expiring contracts.
