GET Single Product K line query（High Low, Open, Close）

English / 中文

GET /kline

Interface Description

This interface can be used to query historical K-line data, but it only allows querying one product at a time. It is recommended to cache the retrieved historical K-lines in a local database.

For clients using the HTTP interface to obtain K-lines, it is advisable to combine the /kline and /batch-kline interfaces as follows:

  • First, use the /kline interface to poll for historical data and store it in a local database. Subsequent historical data can be retrieved directly from the client's database without needing to make additional requests through the interface.

  • Then, continuously use the /batch-kline interface to request the latest two K-lines for multiple products in bulk and update the database with this data.

This method allows for quick updates of the latest K-lines while avoiding limitations on request frequency caused by frequent requests for historical K-lines.
