Query Parameters
Index identifier to query. For Symbol-type identifiers, use the full <SYMBOL>.<GROUP> form (e.g. SPX.IND_CBOM for the S&P 500 in the CBOE CSMI group). For other identifier types (CUSIP, ISIN, etc.), set identifierType accordingly.
"SPX.IND_CBOM"
How to interpret the value you sent in identifier. Defaults to Symbol. See IndicesIdentifierType for the full set of accepted values.
Which kind of identifier you are sending in identifier / identifiers. Provide the matching value:
Symbol— index ticker (e.g.SPX.IND_CBOM). Default.CIK— SEC Central Index Key.CUSIP— 9-character U.S./Canadian security identifier.ISIN— 12-character international identifier.Valoren— Swiss security identifier.SEDOL— 7-character UK identifier.FIGI— Bloomberg Financial Instrument Global Identifier.CompositeFIGI— country-level composite FIGI.
Symbol, CIK, CUSIP, ISIN, Valoren, SEDOL, FIGI, CompositeFIGI "Symbol"
End time for the bar window. Format: MM/DD/YYYY hh:mm am/pm in the index's native timezone (e.g. 12/22/2025 10:30 am).
"12/22/2025 10:30 am"
How long each bar covers. Pair with period to set the exact size (e.g. precision=Minutes, period=5 = 5-minute bars). Allowed values:
Minutes— minute bars (combine withperiodfor 1, 5, 15, 30-minute candles).Hours— hour bars (combine withperiodfor 1, 2, 4-hour candles).
For daily/weekly/monthly bars use GET /v1/indices/chart-bars which supports a Daily precision.
Minutes, Hours "Minutes"
Multiplier on precision to set the bar size. Defaults to 1. Examples: precision=Minutes + period=5 = 5-minute bars; precision=Hours + period=4 = 4-hour bars.
