• get_realized_vol

  FlashAlpha

  Range-based realized (historical) volatility estimators over 10/20/30-day windows: close-to-close, Parkinson, Garman-Klass, Rogers-Satchell, and Yang-Zhang. Range estimators use the daily high/low/open/close and are 5–8× more statistically efficient than close-to-close. Alpha tier. Use to measure realized vol robustly, compare estimators, or feed a vol-risk-premium calc.

• cast_hexagram

  yarrow

  Cast a hexagram for an I-Ching consultation. Returns the primary hexagram, the six lines (6=old yin, 7=young yang, 8=young yin, 9=old yang from bottom to top), any moving lines, and the changing hexagram if there are moving lines. Pass `seed` to make the cast deterministic (useful for testing or for reproducing a reading).

  Connector

• lookup_hexagram

  yarrow

  Return the full classical sources for a hexagram by its number (1–64): judgment (卦辞), image (大象), Tuan commentary, Zhu Xi 周易本义, Yang Tian Cai modern explanation, Yarrow's separately labelled Chinese reading aid, and historical anecdote — with available Chinese and English source material.

• get_iching_hexagrams_lookup

  I Ching MCP Server by RoxyAPI

  Find an I-Ching hexagram by its binary line pattern. Provide 6 digits (0 or 1) representing broken (yin) and solid (yang) lines from bottom to top. Use this for custom divination interfaces where users input their own line configurations, or to find hexagrams matching specific trigram combinations. Example: "111111" returns Hexagram 1 (The Creative), "000000" returns Hexagram 2 (The Receptive).

• get_iching_cast

  I Ching MCP Server by RoxyAPI

  Generate an authentic I-Ching reading using the traditional three-coin casting method. Each of the six lines is determined by virtually tossing three coins, producing values 6-9 where 6 (old yin) and 9 (old yang) are changing lines. Returns the primary hexagram with full interpretation, the line values showing which lines are changing, and if any lines change, the resulting hexagram that the primary transforms into. Optionally provide a seed for reproducible castings. Perfect for divination apps, oracle features, and decision-making tools.
