二、逐笔报价查询

逐笔报价功能允许您获取最新的汇率数据，包括买入价、卖出价、最高价、最低价等详细信息。通过订阅相关频道，您可以实时获取汇率变动的信息。请看下面实例代码：

import time
import requests
import json
# extra headers
test_headers = {
    'content-type': 'application/json'
}
'''
# special note:
# github: https://github.com/alltick/realtime-forex-crypto-stock-tick-finance-websocket-api
# token application: https://alltick.co
# replace "testtoken" in the url below with your own token
# api addresses for forex, cryptocurrencies, and precious metals:
# https://quote.tradeswitcher.com/quote-b-ws-api
# stock api address:
# https://quote.tradeswitcher.com/quote-stock-b-ws-api
encode the following json and copy it to the "query" field of the http query string
{"trace": "python_http_test1", "data": {"code": "700.hk", "kline_type": 1, "kline_timestamp_end": 0, "query_kline_num": 2, "adjust_type": 0}}
{"trace": "python_http_test2", "data": {"symbol_list": [{"code": "700.hk"}, {"code": "unh.us"}]}}
{"trace": "python_http_test3", "data": {"symbol_list": [{"code": "700.hk"}, {"code": "unh.us"}]}}
'''
test_url1 = 'https://quote.tradeswitcher.com/quote-stock-b-api/kline?token=testtoken&query={"trace" : "python_http_test1","data" : {"code" : "700.hk","kline_type" : 1,"kline_timestamp_end" : 0,"query_kline_num" : 2,"adjust_type": 0}}'
test_url2 = 'https://quote.tradeswitcher.com/quote-stock-b-api/depth-tick?token=testtoken&query={"trace" : "python_http_test2","data" : {"symbol_list": [{"code": "700.hk"},{"code": "unh.us"}]}}'
test_url3 = 'https://quote.tradeswitcher.com/quote-stock-b-api/trade-tick?token=testtoken&query={"trace" : "python_http_test3","data" : {"symbol_list": [{"code": "700.hk"},{"code": "unh.us"}]}}'
resp1 = requests.get(url=test_url1, headers=test_headers)
time.sleep(1)
resp2 = requests.get(url=test_url2, headers=test_headers)
time.sleep(1)
resp3 = requests.get(url=test_url3, headers=test_headers)
# decoded text returned by the request
text1 = resp1.text
print(text1)
text2 = resp2.text
print(text2)
text3 = resp3.text
print(text3)

三、批量订阅

批量订阅功能允许您同时查询多个货币对的汇率数据，节省了频繁发送请求的时间和资源消耗。您可以根据需求订阅感兴趣的货币对，获取实时的批量数据。请看下面实例代码：

import json
import websocket    # pip install websocket-client
'''
# special note:
# github: https://github.com/alltick/realtime-forex-crypto-stock-tick-finance-websocket-api
# token application: https://alltick.co
# replace "testtoken" in the url below with your own token
# api addresses for forex, cryptocurrencies, and precious metals:
# wss://quote.tradeswitcher.com/quote-b-ws-api
# stock api address:
# wss://quote.tradeswitcher.com/quote-stock-b-ws-api
'''
class feed(object):
    def __init__(self):
        self.url = 'wss://quote.tradeswitcher.com/quote-stock-b-ws-api?token=testtoken'  # enter your websocket url here
        self.ws = none
    def on_open(self, ws):
        """
        callback object which is called at opening websocket.
        1 argument:
        @ ws: the websocketapp object
        """
        print('a new websocketapp is opened!')
        # start subscribing (an example)
        sub_param = {
            "cmd_id": 22002,
            "seq_id": 123,
            "trace":"3baaa938-f92c-4a74-a228-fd49d5e2f8bc-1678419657806",
            "data":{

                        "depth_level": 5,
                    },
                    {
                        "code": "unh.us",
                        "depth_level": 5,
                    }
                ]
            }
        }
        # if you want to run for a long time, you need to modify the code to send heartbeats periodically to avoid disconnection, please refer to the api documentation for details
        sub_str = json.dumps(sub_param)
        ws.send(sub_str)
        print("depth quote are subscribed!")
    def on_data(self, ws, string, type, continue_flag):
        """
        4 arguments.
        the 1st argument is this class object.

        print(result)
    def on_error(self, ws, error):

        """
        print(error)
    def on_close(self, ws, close_status_code, close_msg):
        """
        callback object which is called when the connection is closed.
        2 arguments:

        @ close_msg
        """
        print('the connection is closed!')
    def start(self):
        self.ws = websocket.websocketapp(
            self.url,
            on_open=self.on_open,
            on_message=self.on_message,

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

以上实时外汇汇率api提供了丰富的功能和灵活的接口，使开发者能够轻松获取汇率和行情数据。通过逐笔报价、批量订阅和历史k线等特性，您可以在自己的应用中实时展示最新的汇率信息，并进行相应的数据分析和决策。

目前国内可用的金融行情api并不多，实时的高频数据接口就更少了，这些都以国外的产品为主，详细的选购教程可以看。
