0DTE on SPX
0DTE options expire on the same trading day. That puts timing, liquidity, and a clear intraday plan at the center.
Introduction
Why SPXW fits this style
0DTE is usually best traded through liquid, cash-settled indices. Those products tend to offer cleaner execution and more manageable risk than smaller or less liquid names.
SPXW stands out because these are European-style, cash-settled index options. There is no physical stock delivery.
Regular PM-settled contracts trade until 4:00 p.m. ET on expiration day. After that, the expiring contract stops trading without the typical stock-delivery process seen in many US equity options.
Later on, the workflow can be expanded with the OWS Tools. For now, this page is only about the basic structure.
