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?
