Finds call and put contracts trading far above their open interest, estimates whether buyers or sellers drove the trades, and ranks the strongest short-dated setups.
Cards are ranked by unusual score. They are candidates to research, not instructions to trade.
| Contract | Score | Side (est.) | Volume | Open int. | Vol/OI | Premium $ | DTE | OTM % | Bid / Ask | Spread % | IV | Delta | Move to B/E |

Free delayed chains from Cboe (about 15 minutes behind). On a computer: open a ticker link, save the page (Ctrl+S / Cmd+S) as a .json file, then drop it here. You can load several tickers at once. Barchart “Unusual Options Activity” CSV exports also work.
Score (0–100) adds up: Vol/OI ratio (30 pts, 1× → 10×), dollar premium traded (20 pts, $20k → $5M), trade side (20 pts if the last trade printed at or near the ask), short expiry (10 pts for ≤ 7 days), tight spread (10 pts for ≤ 5%), and strike (10 pts for in-the-money delta 0.50–0.80, which tracks the stock closely and loses value more slowly than cheap out-of-the-money contracts).
Where the data comes from. A scan runs every 5 minutes during US market hours (Monday to Friday). It reads Cboe’s free options chains for 20 popular tickers, which are about 15 minutes behind the market, and keeps contracts whose volume is at least equal to their open interest. Refresh and auto-refresh load the newest scan.
Side (est.) compares the last trade price with the current bid and ask. Near the ask suggests buyers paid up; near the bid suggests sellers hit it. Free chain data has daily totals, not every trade, so this is an estimate. Real sweep and block detection needs paid trade-by-trade (OPRA) feeds.
Move to B/E is how far the stock must move by expiry for the option to break even if you paid the ask. Large unusual volume can also be hedges, spreads or closing trades, so it does not always mean a directional bet.
Short-dated options can lose most of their value in hours. This tool is for research and is not financial advice.
