Real-Time Options Chain API Data Aggregation Pipeline

Design a sophisticated Python data pipeline using pandas and requests that can simultaneously fetch real-time options chain data from multiple financial APIs (e.g., Alpha Vantage, Yahoo Finance, IEX Cloud). Create a robust error-handling mechanism that can handle rate limits, authentication failures, and partial data responses. Implement a caching strategy using Redis to minimize redundant API calls and reduce overall latency. The solution should support dynamic filtering of options contracts by strike price, expiration date, and underlying asset volatility.
