Market Data API FAQs
Common questions about MyStocks market-data freshness, history, symbols, keys, and redistribution.
Are prices tick-by-tick?
No. Partner market data is pull-based and refreshes according to the documented market-data cadence. Events and SSE are not a tick stream.
How do I identify a symbol?
Use the canonical SYMBOL.EXCHANGE value returned by GET /stocks and do not infer exchange from a company name.
Does a data key allow trading?
No. Data keys are read-only and limited to market-data routes.
Is historical depth identical for every exchange?
No. History depth varies by exchange and instrument. Inspect historyConfidence and treat missing history as a data characteristic, not a zero-price series.
May I redistribute the data?
Only within the permissions and attribution requirements in Data Licensing.
