Which Strike?
Important support and resistance levels to watch when selling options or LPing tokenized stocks.
About Which Strike
Which Strike answers one question for options sellers and liquidity providers: given a ticker, which prices matter right now? It gathers the levels a discretionary trader would otherwise compute one at a time, puts them in one table, and flags the prices where several independent methods agree.
What it does
Enter a ticker and the page lists the current price, IV rank and percentile, and every level from ten indicators: expected moves from implied volatility, simple moving averages, the 52-week range, volume at price, dealer gamma exposure, max pain, Fibonacci pivots, RSI thresholds, and the VIX futures curve. Rows where two or more indicators land within 0.15% of each other are highlighted, because a price that several methods point at tends to matter more than one that a single method produces. Any row opens a candlestick chart with the level drawn on it and the formula behind it.
Who it is for
Traders who sell covered calls, cash-secured puts, credit spreads or iron condors and want a defensible strike. Liquidity providers on Uniswap and similar pools who hold tokenized stocks or ETFs and need a range that respects where price has reacted before. Anyone who would rather read one table than run the same six indicators by hand every morning.
Where the data comes from
Stock, ETF, options and futures data comes from Massive (daily and minute aggregates, snapshots and option contract history). Earnings dates come from Finnhub. Quotes are 15-minute delayed. Implied volatility history is solved daily from each day's option closes, because no vendor keeps it. Everything is computed on request and cached briefly; nothing is hand-edited.
Who makes it
Which Strike is built and run by @blauyourmind, a solo developer and options trader. There is no company behind it, no sales team, and no data resale. Subscriptions pay for the market-data feeds.
What it is not
It is not investment advice, not a broker, and not a signal service. Levels are places where price has historically reacted, not predictions. Nothing on the site knows your position, your risk tolerance or your tax situation. Do your own research and size accordingly.
