# 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.

African equity quotes are supplied by the exchanges on a 15-minute-delayed basis. MyStocks targets
a 15-minute API refresh cadence during the published coverage window. Read `asOf` on every response;
do not describe the value as live or real-time.

## Does the 15-minute delay mean MyStocks lacks exchange data rights?

No. MyStocks holds full market-data rights for every supported exchange. Fifteen-minute delay is the
latency class of the exchange-supplied feed. It is not a licensing or entitlement gap.

## Can every African stock render a chart?

Yes, every listed African equity has EOD data for a line chart. Not every instrument has complete
reported OHLCV. Use `/stocks/{symbol}/candles` and follow `meta.recommendedChartType`; show
candlesticks only when the response recommends them, otherwise use the EOD close line.

## 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](/partners/docs/data-licensing).
