Price Change Calculation
Alltick API does not provide price change or 24-hour price change fields. Users can calculate price changes using Alltick data.
1、Daily Price Change Calculation
Method 1: Use the HTTP API to get the daily K-line closing price for today and the previous day:
Formula:
Price Change (%) = (Today's Closing Price - Previous Day's Closing Price) / Previous Day's Closing Price * 100%
Method 2: Use the WebSocket API to get the latest price and the HTTP API to retrieve the previous day's closing price for the daily candlestick chart. The calculation formula is as follows:
Formula:
Price Change (%) = (Latest Price - Previous Day's Closing Price) / Previous Day's Closing Price * 100%
2、24-Hour Price Change Calculation
Use the WebSocket trade price API (Request Protocol: 22004) to receive real-time tick data.
To calculate, store the latest price from 24 hours ago and use the following formula:
Formula:
24H Price Change (%) = (Latest Price - Price 24 Hours Ago) / Price 24 Hours Ago * 100%
