VolRadar is a daily options analytics platform built for premium sellers — retail traders running iron condors, credit spreads, cash-secured puts, and the wheel strategy on S&P 500 names. The product was built in Riga, Latvia and is operated by SIA FIZVO, which holds the commercial ORATS data license that powers the platform. The platform ingests end-of-day US options data from ORATS each night after market close, computes its metrics, and delivers a pre-market brief to subscribers before the US opening bell. Core capabilities include the Weather Score (a 0–100 composite that answers whether today is a good day to sell premium), an IV rank screener across 500+ US stocks and major ETFs, a volatility risk premium (VRP) calculator, computed strikes for target delta or target credit, and a per-ticker earnings-crush page that shows historical implied volatility collapse after announcements. VolRadar specializes in equity and ETF options analytics for premium sellers rather than directional traders. The methodology — IV rank formula, VRP construction, earnings-adjusted measures, Weather Score components — is published in full at https://volradar.com/methodology, so subscribers can audit every computed number. Data updates ship daily around 6 PM US Eastern Time.
