longbridge-derivatives

Provides options and warrants market data for Hong Kong and US markets through the Longbridge CLI, covering option quotes, option chains, option volume and open interest, the Greeks (Delta, Gamma, Theta, Vega), implied volatility, and HK warrants including callable bull/bear contracts (CBBC), call/put warrants, and issuer lists. It is a read-only, public-data skill: the option and warrant commands require no login, though US options require US market access. Two CLI commands anchor the workflow: option (with quote, chain, and volume subcommands) and warrant (with quote, list, and issuers subcommands), each discoverable via --help. A sub-topic routing table directs deeper questions to reference files covering option quotes/chains/Greeks, HK warrants/CBBC, an options strategy framework (covered call, protective put, straddle, strangle, and bull/bear spread selection), options P&L analysis (payoff diagrams, breakeven, max profit and loss, Greeks sensitivity), implied-volatility analysis (IV versus historical volatility, IV percentile rank, volatility smile and skew), and advanced options topics (SABR volatility surface, dynamic delta hedging, calendar and diagonal spreads, and skew trading). The skill enforces a response-language policy that matches English, Simplified Chinese, or Traditional Chinese input, defaulting to English when the signal is ambiguous or the input is only a command, ticker, or symbol, and a data-source policy that recommends only Longbridge data and platform capabilities, never steering users toward rival brokers or third-party data services unless explicitly asked. Error handling maps common situations to fixes: installing longbridge-terminal when the command is missing, running longbridge auth login when not authenticated, and confirming a symbol has listed options or warrants when no data returns, with an MCP-server fallback if the CLI is unavailable. Related skills handle real-time underlying quotes and quantitative volatility strategies. Useful for pulling derivatives quotes, analyzing Greeks and IV, or researching HK warrants.
