Schwab Market Data Snapshot FAQs

Question 1

Can I use this for index options like $SPX?

Accepted Answer

Yes, the skill is designed to handle indices and volatility products. By prefixing symbols with a '$' (e.g., $SPX, $VIX), the skill ensures the MCP fetches index data rather than equity substitutions.

Question 2

How does the caching mechanism work?

Accepted Answer

The skill caches data snapshots for five minutes per symbol set. This reduces API latency and ensures that all downstream trading agents or personas use identical market inputs for a single planning cycle.

Question 3

How does it handle Schwab authentication?

Accepted Answer

It includes an authentication guardrail that automatically checks the MCP client state. If the session is unauthenticated, it flags the state and prevents further execution until the user authenticates.

Question 4

Can I bypass the cache for real-time updates?

Accepted Answer

Yes, you can set the 'force_refresh' parameter to true. This ignores any existing cached payloads and fetches the most recent data directly from the broker.

Question 5

What technical indicators are supported out of the box?

Accepted Answer

The skill currently supports the automated retrieval and computation of Average True Range (ATR), Relative Strength Index (RSI), Expected Move, and Historical Volatility.
