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 the previous day’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 that was 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%
