Charts and OHLCV

Render currency-correct stock and ETF charts using chart-ready series or OHLCV candles from MyStocks.

Use the chart endpoints when your UI needs labels, local-currency prices, converted USD history, and a ready-to-render series. Use /market/ohlcv when your analytics pipeline needs open, high, low, close, volume, and candle timestamps.

Rendering checklist

  • Label the exchange and native currency.
  • Show the data timestamp and freshness.
  • Do not mix local-currency and USD series on the same axis.
  • Handle markets with sparse history or closed sessions.
  • Treat volume 0 as no recorded trades, not as missing price data.
  • Include the instrument symbol and exchange in exports.

See Historical Market Data for endpoint selection and Quotes and Market Status for current-market context.
