OptionStrat combines strategy building, optimization, and options flow for comparing multi-leg positions and researching unusual activity.
About
OptionStrat groups strategies by complexity and purpose, including single options, spreads, straddles, iron condors, and calendars. Its navigation connects the strategy builder, optimizer, and flow tools. Choose a structure before considering expiration, strike selection, and market assumptions.
The public flow page states a 15-minute delay and shows only some alerts; full access requires an upgrade. The site also describes calculations as estimates that do not account for every market condition or event. Check outputs against actual quotes and costs.
