请求 K 线数据

import time
import requests
import json
 
# Extra headers
test_headers = {
    'Content-Type':'application/json'
}
 
'''
github: https://github.com/alltick/realtime-forex-crypto-stock-tick-finance-websocket-api
申请免费 token: https://alltick.co/register
官网: https://alltick.co
将如下 JSON 进行 url 的 encode ,复制到 http 的查询字符串的 query 字段里
{"trace":"python_http_test1","data":{"code":"AAPL.US","kline_type":1,"kline_timestamp_end":0,"query_kline_num":2,"adjust_type":0}}
'''
test_url1 = 'https://quote.tradeswitcher.com/quote-stock-b-api/kline?token=e945d7d9-9e6e-4721-922a-7251a9d311d0-1678159756806&query=%7B%22trace%22%3A%22python_http_test1%22%2C%22data%22%3A%7B%22code%22%3A%22AAPL.US%22%2C%22kline_type%22%3A1%2C%22kline_timestamp_end%22%3A0%2C%22query_kline_num%22%3A2%2C%22adjust_type%22%3A0%7D%7D'
 
resp1 = requests.get(url=test_url1, headers=test_headers)
 
# Decoded text returned by the request
text1 = resp1.text
print(text1)

上面代码中是以查询苹果股票(AAPL)分钟 K 线为例子的,如果想查询其它类型的 K 线数据则 kline_type 传入以下值:1-分钟 K ,2-为 5 分钟 K ,3-为 15 分钟 K ,4-为 30 分钟 K ,5-为小时 K ,6-为 2 小时 K ,7-为 4 小时 K ,8-为日 K ,9-为周 K ,10-为月 K 。

请求最新报价成交数据

import time
import requests
import json
 
# Extra headers
test_headers = {
    'Content-Type':'application/json'
}
 
'''
github: https://github.com/alltick/realtime-forex-crypto-stock-tick-finance-websocket-api
申请免费 token: https://alltick.co/register
官网: https://alltick.co
将如下 JSON 进行 url 的 encode ,复制到 http 的查询字符串的 query 字段里
{"trace":"python_http_test2","data":{"symbol_list":[{"code": "700.HK"},{"code": "UNH.US"},{"code": "600416.SH"}]}}
'''
test_url1 = 'https://quote.tradeswitcher.com/quote-stock-b-api/trade-tick?token=e945d7d9-9e6e-4721-922a-7251a9d311d0-1678159756806&query=%7B%22trace%22%3A%22python_http_test2%22%2C%22data%22%3A%7B%22symbol_list%22%3A%5B%7B%22code%22%3A%20%22700.HK%22%7D%2C%7B%22code%22%3A%20%22UNH.US%22%7D%2C%7B%22code%22%3A%20%22600416.SH%22%7D%5D%7D%7D'
 
resp1 = requests.get(url=test_url1, headers=test_headers)
 
# Decoded text returned by the request
text1 = resp1.text
print(text1)

上面代码中 symbol_list 是可以同时传入多个的,分别传入不同的市场的产品也是可以的。

获取最新盘口报价数据

    'Content-Type':'application/json'
}

resp1 = requests.get(url=test_url1, headers=test_headers)
 
# Decoded text returned by the request
text1 = resp1.text
print(text1)

同上,symbol_list 支持传入多个值。

通过 Websocket 订阅实时行情数据

        self.ws.run_forever()
 
 
if __name__ == "__main__":
    feed = Feed()
    feed.start()

上面的代码中 symbol_list 代表你要订阅的产品列表,可以同时传入多个市场的多个产品,cmd_id=22002 是订阅盘口数据,当 cmd_id=22004 时订阅的是成交报价,一旦订阅成功,实时股票行情数据就会源源不断的推送过来,并且是及时的。
