Current VIX level + 5-tier fear-thermometer classification + option-seller strategy hint. Translates the single VIX number into actionable trading guidance (calm / normal / seller sweet spot / caution / extreme fear). Includes current percentile vs 1-year history and how many days the market spent in each tier. Triggers: "what's VIX", "VIX level", "is market calm", "market fear gauge", "should I sell premium now", "VIX tier", "VIX strategy", "volatility environment", "fear index", "should I buy protection", "is this a good time for BPS".

Quantified version of David Tepper's 2009 (+132%) and 2020 (+82%) panic-buy playbook. Detects whether current conditions match Tepper's signal: VIX ≥ 35 AND FearScore ≥ 80 AND quality filter (large-cap, positive margin). Only fires during genuine market panics — the rest of the time it returns the "waiting" state, which is ~80% of all days per Tepper's own framework. The API reuses our existing FearScore module, so the signal is directly comparable to the multi-indicator panic index. Triggers: "is this a Tepper buy signal", "panic-buy detector SPY", "should I buy the panic", "Tepper style entry check", "are we at a panic bottom", "is VIX 35+ and fear 80+", "historical bottom signal today"

Quantifies whether a stock is suitable for long-term holding or requires tiered profit-taking — using a novel "rollercoaster rate" metric (probability that an entry's paper profit reaches +50% then falls back >50% from peak before exit). Runs 15 exit strategies over ~10 years of daily history per ticker and returns medians for each. First query for a new ticker takes ~30s and gets cached globally; subsequent queries are instant. Triggers: "should I hold TQQQ long-term", "take-profit strategy for NVDA", "is AAPL holdable", "rollercoaster rate for TSLA", "sell strategy COIN", "when to sell NVDA", "profit-taking plan for QQQ", "exit strategy for my stock", "leveraged ETF hold analysis"

Full walk-forward Bull Put Spread backtest over ~8 years of daily history. Runs both the signal (FearScore ≥ 60 entry) version AND a no-signal control in the same request, so you can quantify whether the fear-entry rule actually delivers alpha for this ticker under your parameters. Returns equity curve, 4 KPIs (annualized return / win rate / max drawdown / Sharpe), trade ledger, and a plain-language takeaway. Triggers: "backtest BPS on QQQ", "bull put spread backtest", "does FearScore work on SPY", "what DTE for BPS", "optimal bull put spread delta", "BPS strategy backtest", "credit spread backtest", "backtest short put spread"
