OHLCV is the financial market standard representation of market price movements at different granularities (e.g. 1 mn, 5 mn, 1 hour, 12h, 24h). Kaiko OHLCV is a proprietary data aggregate built on top of tick trades allowing customers to ingest high quality time-aggregated data in real time. We provide real-time OHLCV data for over 100 exchanges and 90,000+ instruments, in real time for custom and user defined time granularity. Our OHLCV service is customer oriented, obeying a data-as-a-serviuce approach. Users define : - What exchanges - What instrument - What time granularity And get their real-time OHLCV data feed set-up. Documentation is available here : https://docs.kaiko.com/#ohlcv-candles We cover (i) Centralized EXchanges (e.g. Coinbase, Kraken, Binance, Huobi) - CEXes (ii) Decentralized EXchanges (e.g. Uniswap) - DEXes: our coverage is rapidely expanding. The source is transparent for the users, data is equally normalized across both DEXes and CEXes sources. Kaiko Real time CEX sourced data is collected via a redundant web-socket cluster (to mitigate connectivity issues, packet loss and optimize latency - network route in-determination of exchanges web services) backed by an automatic REST back-fill process. Kaiko Real time DEX sourced data is collected via dedicated blockchain nodes (e.g. ethereum, BSC) to fetch trade data events from the DEXes protocol smart contracts / the blocks - depending on each protocol implementation. Our infrastructure covers the different stacks for a seamless feed from user perspective - who do not have to cope with this complexity.
