Tools
| Tool | Description | Behaviour |
|---|---|---|
| get_dataset_stats | Discover what data is available before querying: date ranges, contract counts, symbol counts and sector coverage for the unusual-activity dataset and its daily aggregates. Call this first when unsure about available history. | Not declared |
| get_expiry_concentration | Where the day's unusual premium sits along the expiry axis, in DTE buckets (0-7, 8-30, 31-90, 90+) with call/put splits. Heavy short-dated premium reads as event bets; heavy long-dated as positioning. | Not declared |
| get_flow_history | End-of-day series of one symbol's UNUSUAL options flow (aggregated from the contracts that passed the unusual filter - not the full tape): daily call/put volume, premium, C/P ratios, average IV, net delta and the consecutive-day streak. ~75 trading days - the series behind back-tests and 'how has unusual flow on NVDA developed?' | Not declared |
| get_flow_sentiment | Bullish/bearish classification of each symbol's unusual flow with a 0-9 strength score, based on call/put volumes, premium and net delta. Pass a symbol for that ticker's sentiment time series (date_from, date_to, limit apply); omit it for the cross-market snapshot (filterable by sector, side, minimum strength or premium). | Not declared |
| get_flow_streaks | Symbols with unusual options activity on N+ consecutive trading days, with the dominant side (call/put). Persistent unusual flow is a stronger signal than a single print - use for 'where does money keep showing up?' | Not declared |
| get_iv_rank | IV rank and IV percentile per symbol against its rolling history (needs 20+ days). Pass a symbol for its IV-rank time series (lookback_days, limit apply); omit it for a ranked snapshot (e.g. side=put&min_rank=0.8 finds elevated put IV; side=both ranks by the higher of call/put IV rank). | Not declared |
| get_market_regime | Market-wide breadth of unusual flow per trading day: breadth score 0-100, aggregate call/put ratio, regime label (bullish/bearish/mixed) and signal counts. Use for 'what's the overall tone of the unusual-flow tape?' | Not declared |
| get_oi_changes | Day-over-day open-interest change per symbol (total, calls, puts) - fresh positioning being built or unwound. Pass a symbol for its OI-change series (date_from, date_to, limit apply); omit it for market-wide gainers/losers. | Not declared |
| get_sector_flow | Which sectors the day's unusual options premium is concentrating in: total premium, volume, average net delta and bullish/bearish symbol counts per sector label (11 GICS sectors plus Diversified, Unknown and Unclassified; only labels with activity, at most 14 rows). | Not declared |
| get_symbol_flow | Every unusual contract on a single ticker, ranked by score (Vol/OI weighted by premium). Use when the question is about one specific stock's unusual options flow. | Not declared |
| get_top_prints | The day's biggest options bets ranked by estimated premium - the same view OptionsBell alert emails lead with. Perfect for 'what were the largest options trades today?' | Not declared |
| get_unusual_activity | Contract-level unusual options activity scan across 7,000+ US stocks (the dataset behind OptionsBell alerts). Filter by symbols, side and thresholds: Vol/OI ratio, premium (USD), IV, days-to-expiration, volume, open interest. Rows include strike, expiry, volume, open interest, IV, delta, sector and an estimated premium. Use for questions like 'what unusual put buying hit TSLA today?' | Not declared |
