GET
Historical price series
The chart endpoint returns the complete OHLCV (open, high, low, close, volume) history for a company sourced directly from daily exchange records. Each data point includes a timestamp, date, and full OHLCV fields alongside VWAP (volume-weighted average price), trade count, and daily change. Use from and to (YYYY-MM-DD) to narrow results to a specific date range, or use the period parameter to request a named time window (7d, 30d, 90d, 1y, 5y, all). Three format options let you pick the shape that fits your charting library:
  • detailed (default) — full objects per day. Includes price as an alias for close for backward compatibility, plus open, high, low, close, volume, value_traded, vwap, trade_count, change, change_percent.
  • chart — compact [timestamp, close] arrays. Backward-compatible with the previous API behaviour, suited for line charts.
  • ohlcv — compact [timestamp, open, high, low, close, volume] arrays. Pass this directly to TradingView Lightweight Charts, ApexCharts, or Highcharts candlestick series.
A statistics block summarises the full range — first/last price, min, max, and total change — so you can render a summary card without extra computation. For example, to fetch one year of DANGCEM data in candlestick format:
