This endpoint returns a time series of daily closing prices for a specific NGX ETF or ETP. Use period for a named lookback window (7d, 30d, 90d, 1y, 5y, all) or supply from and to for a custom date range. In detailed format each row includes OHLCV data alongside a normalized field that rebases the price to 100 at the start of the requested period — useful for comparing two ETFs on the same scale. The chart format returns compact [date, price] pairs suited for line charting libraries. The statistics block includes return_1m, return_3m, return_1y, and return_ytd — percentage returns versus fixed historical reference points, computed independently of the period you requested. For example, to fetch one year of STANBICETF30 daily closes in chart-ready format:

curl "https://api.ngnmarket.com/v1/etfs/STANBICETF30/chart?period=1y&format=chart" \
  -H "Authorization: Bearer ngm_live_YOUR_KEY"
