Four free calculators, no signup: IV Rank lookup, Expected Move calculator (1SD/2SD), Options Profit Calculator with 14 preset strategies, and Wheel Strategy tracker with cost-basis through assignment. Explore the full calculators suite.

Hey Fazier 👋 I built VolRadar because every trading morning I was burning 30–60 minutes checking IV Rank on 30 tickers, cross-referencing earnings, eyeballing VIX term structure, and then guessing where to place short strikes on the wheel and iron condors. The workflow was slow and inconsistent — on choppy weeks I'd talk myself into trades that didn't actually have edge. I wanted three things: — A single number telling me whether today is a good day to sell premium at all (that became the Weather Score). — A VRP-based ranking across S&P 500 so I'm not just chasing high IV (which can be a trap when realized catches up). — Pre-computed short strikes so the 1SD/2SD math isn't redone for 30 tickers every morning. Built the first version for myself through 2024, ran it through a full earnings season, then kept adding pieces that actually changed my trading — the scanner, the wheel tracker (cost basis through assignment matters more than most tools admit), the pre-market brief. Launched in April 2026 as a freemium product so the rest of the theta gang can use the same engine. Free tier forever. Starter $19/mo. Bootstrapped solo from Latvia. Feedback especially welcome from anyone running the wheel, iron condors, or credit spreads — what's missing from the daily workflow?
The "Weather Score" single-number concept is exactly right for how traders actually make morning decisions — nobody wants to synthesize 10 data points before the open. What I'd love to know: how are you handling the earnings calendar overlap? That's where IV rank becomes genuinely misleading and I'd imagine it's the trickiest edge case to get right in the scanner.
The VRP ranking using Yang-Zhang realized vol is a smart differentiator — most retail tools just show IV Rank and call it a day, but VRP is the actual edge signal for premium sellers. Weather Score as a regime gate is the right UX call too: it abstracts the multi-factor read into a single go/no-go so traders don't second-guess themselves in the morning rush. The pre-computed 1SD/2SD short strikes alone could save 20 minutes per session for active wheel runners. Would be curious whether you plan to add a journal/tracking layer to record which setups actually hit the profit target post-expiration — closing the feedback loop would make this a full workflow tool.
The Weather Score concept is clever — having a single 0-100 signal that tells you whether to sell premium at all is exactly the kind of filter that prevents costly mistakes on low-edge days. The pre-market brief at 8:30 AM ET sounds very practical for busy traders. How does the VRP ranking handle earnings season when IV tends to spike artificially? Do you filter those tickers out automatically?
