K-Line Push (Not Supported)

Learn K-Line Push (Not Supported) for AllTick WebSocket API, including connection setup, subscription messages, real-time quote streaming and request examples.

K-Line Push Description

AllTick WebSocket interfaces do not support K-line data push. Because many customers have questions about this, this document explains that both historical K-lines and real-time K-lines are currently supported only through direct HTTP interface retrieval. The recommended implementation is as follows:

Implementation suggestions (for reference only):

1. Periodically pull K-lines: To quickly update K-lines, it is recommended to purchase a plan with a higher request frequency to increase the pull frequency.

2. Use HTTP interfaces together: We recommend using /kline and /batch-kline together as follows:

• First, use the /kline interface to poll historical data and store it in a local database. Later historical data can be obtained directly from the customer’s database without requesting the interface again.
• Then, continuously use the /batch-kline interface to batch request the latest two K-lines for multiple products and update the database with the data.

This approach can quickly update the latest K-lines while avoiding request frequency restrictions caused by frequent historical K-line requests.

Price Change Description

AllTick interfaces do not provide a price change or 24-hour price change field. Customers can calculate price changes themselves by obtaining AllTick data.

1. Daily price change calculation methods:

• Method 1: Use the HTTP interface to obtain today’s daily K-line closing price and the previous day’s daily K-line closing price. The formula is:

Price change = (today’s closing price - previous day’s closing price) / previous day’s closing price * 100%

• Method 2: Use the WebSocket interface to obtain the latest price, and use the HTTP interface to obtain today’s daily K-line closing price. The formula is:

Price change = (latest price - previous day’s closing price) / previous day’s closing price * 100%

2. 24-hour price change calculation method:

• Use the WebSocket latest trade price interface (request protocol number: 22004) to receive tick-by-tick trade prices in real time.
• You need to store the latest price from 24 hours ago pushed by the WebSocket interface for subsequent calculation.
• Formula:

24-hour price change = (latest price - latest price 24 hours ago) / latest price 24 hours ago * 100%
