OHLCV Candlesticks

What is this endpoint for?

This Stream delivers the OHLCV for an instrument on an exchange in real-time.

Parameters

Parameter	Description	Examples
aggregate	The period you would like the OHLCV aggregation to be calculated over.	1m
instrumentCriteria	A nested object to configure following properties for your stream: exchange (String) - The code(s) for the exchange(s) instrument_class (String) - The class(es) of the instrument(s) . code (String) - The Kaiko code for the instrument. Explore instruments, codes and exchanges in the Instrument Explorer or by using the Reference API endpoint.	cbse spot btc-usd

Configuring a wildcard

A wildcard allows you to request all information we have on a specific instrument, class, or exchange in the same stream. Use a * in place of the relevant exchange, instrument, or class parameter.

For example, the configuration below would deliver trades for BTC/USD across all exchanges where it’s supported:

exchange: * class: spot instrument: btc-usd

Fields

Field	Description
aggregate	The period of calculation.
class	The class of instrument.
close	Closing price of interval. null when no trades reported.
exchange	The exchange the OHLCV is referencing.
high	Closing price of interval. null when no trades reported.
low	Lowest price during interval. null when no trades reported.
open	Opening price of interval. null when no trades reported.
code	The instrument code.
timestamp	The timestamp for the interval.
uid	The unique ID for this delivery.
volume	Volume traded in interval. 0 when no trades reported.
sequenceId	Not applicable. Null
