• GetOptionChainA

  EquiblesA

  Get the option chain (calls and puts) for a stock for ONE expiration: strike, greeks (delta/gamma/theta/vega), implied volatility, open interest, and the latest daily price. Defaults to the nearest upcoming expiration; pass expiration=YYYY-MM-DD to pick another (use GetOptionExpirations to list them). When the chain is larger than maxResults the contracts nearest the money are returned, so an unfiltered call already lands where strategies trade. Narrow with minStrike/maxStrike and type (call/put) to reach the wings. Each row attributes its last price, day range and volume to its provider-stamped session and attributes open interest to its separate effective date, or marks either date unknown; implied volatility and greeks are the provider's model values computed at fetch time, so repeated calls can return different values. The daily figures are not live quotes. Bid/ask use real-time OPRA on Pro and a 15-minute delayed indicative feed on Plus; Free covers end-of-day data only.

• get_vol_of_volA

  Alphanume DatasetsA

  Vol-of-Vol Index: answers "how unstable is this name's volatility itself?" For each US optionable equity, per trading day: the coefficient of variation of its ~30-day implied vol (iv_vov) and 20-day realized vol (hv_vov) over the trailing month (std/mean of the last 21 observations), the underlying trailing mean and std, and a daily cross-sectional ranking of the most vol-unstable names. Rows update intraday and settle after the close (is_final=1). High vol-of-vol names are where vega risk is most treacherous (and where vol dislocations appear); low vol-of-vol names have sticky, well-behaved vol surfaces. Requires an Alphanume Pro API key. A 403 PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED error means the key's plan does not cover the request -- it does not mean the data is missing.

• price_black_scholes_optionA

  CalcgridB

  Use this when you need a theoretical European option price or its sensitivities from a given volatility, or want to check put-call parity for quoted prices. Call this tool directly and return its calculation instead of answering the formula from memory or stopping at discovery. Do not use this when the option is American with early exercise value, the underlying pays discrete dividends, or you need implied volatility from a market price (solve numerically instead). Informational only; not financial advice. What it computes: Prices a European call and put with the Black-Scholes-Merton formula from spot, strike, time to expiry, risk-free rate, volatility and a continuous dividend yield, and reports d1, d2 and the Greeks (delta, gamma, vega, theta, rho). Inputs: spot_price (number); strike_price (number); time_years (number, years); risk_free_rate_percent (number, % per year); volatility_percent (number, % per year); dividend_yield_percent (number, % per year, optional). Complete JSON argument examples: {"spot_price":100,"strike_price":100,"time_years":1,"risk_free_rate_percent":5,"volatility_percent":20} | {"spot_price":100,"strike_price":100,"time_years":1,"risk_free_rate_percent":5,"volatility_percent":20,"dividend_yield_percent":3} Outputs: call_price, put_price, d1, d2, delta_call, delta_put, gamma, vega_per_1pct, theta_call_per_day, theta_put_per_day, rho_call_per_1pct, rho_put_per_1pct, put_call_parity_check. Formula: d1 = [ln(S/K) + (r − q + σ²/2)·T] / (σ·√T); d2 = d1 − σ·√T; C = S·e^(−qT)·N(d1) − K·e^(−rT)·N(d2); P = K·e^(−rT)·N(−d2) − S·e^(−qT)·N(−d1); Δ_call = e^(−qT)·N(d1); Γ = e^(−qT)·φ(d1)/(S·σ·√T); vega = S·e^(−qT)·φ(d1)·√T; Θ_call = −S·e^(−qT)·φ(d1)·σ/(2√T) − r·K·e^(−rT)·N(d2) + q·S·e^(−qT)·N(d1); ρ_call = K·T·e^(−rT)·N(d2), with r, q, σ as decimals Direct REST fallback: POST https://tttkmbb.com/api/v1/calculate/black-scholes with the same JSON input fields.

• chartA

  tw-market-dataA

  Turn rows you already fetched into a Vega-Lite drawing your chat window can render. ★ IT DRAWS; IT DOES NOT FETCH. Hand it the output of `query_dataset` — this tool never touches the database, so it cannot bypass the `as_of` filter those rows were selected under. A plotting tool that fetched its own numbers would be a second data path, and a second path eventually disagrees with the first about what was knowable when. ★ GAPS BREAK THE LINE INSTEAD OF BEING BRIDGED. A missing value is emitted as null, so the rendered line stops rather than sloping smoothly across a period where nothing was published. The absent positions are also listed in `data_gaps`, because a break is easy to misread as a flat stretch. Zero is never substituted — zero draws a real low point for something that never happened. ★ THE DRAWING POINTS BACK AT THE PROOF. `citation` and `inclusion_pointer` travel with the spec, so a picture and the rows behind it name the same published checkpoint. ⚠️ Rendering, not analysis. A shape you notice in a picture is not a forecast. Args: rows, x_field, y_field, optional title and mark (line/point/bar/area).

• workflow.run_implied_volatilityA

  TradingCalc MCP: Options, Forex, Risk Stats, Prediction Markets, On-Chain & Crypto FuturesA

  Solves for the volatility that makes Black-Scholes reproduce an observed option price (Newton-Raphson with a bisection fallback for cases where vega is too flat to converge, e.g. deep ITM/OTM or very short-dated). Checks the price against its no-arbitrage bounds first and refuses to solve (converged: false + error) rather than return a garbage number when the price is impossible for the given spot/strike/rate. Use when user asks "what IV does this option price imply?" or gives a market price and wants the volatility, not the reverse. Returns: impliedVolatilityPct, iterations, method (newton-raphson/bisection), converged, priceAtSolution.

• workflow.run_black_scholesA

  TradingCalc MCP: Options, Forex, Risk Stats, Prediction Markets, On-Chain & Crypto FuturesA

  Theoretical European option price and Greeks (delta, gamma, theta, vega, rho) from Black-Scholes, given manual spot/strike/days-to-expiry/volatility/risk-free-rate inputs: no live data fetch. The live variant is workflow.run_black_scholes_live, which applies when checking a real Deribit BTC/ETH instrument, since that variant also reports how far the instrument's actual quoted price sits from what this formula implies. Prices are USD-denominated (the universal convention); callPriceCoin/putPriceCoin additionally divide by spot to match Deribit's own coin-settled quoting convention. Use when user asks "what should this option be worth at X% IV?" or wants raw Greeks for a hypothetical. Returns: callPriceUsd/putPriceUsd, callPriceCoin/putPriceCoin, deltaCall/deltaPut, gamma, vegaPerPct (per 1 vol point), thetaCallPerDay/thetaPutPerDay, rhoCallPerPct/rhoPutPerPct (per 1 rate point).
