Recently, the old Zhang head of stock speculation loss of pants are almost gone, have to say that because they did not get real-time data. In fact, nowadays, the Internet can just pull to the historical data, the key is that you have to know where to find, how to get down fast. This time we have to talk about the protagonist of today's -proxy IPThe following is a list of the most common types of products that are used in the world.ipipgoThis artifact, keep you down data like a rocket.

Why do I need to use a proxy IP to download stock data?

For example, you must have encountered this situation: dozens of CSV files in a row to be blocked by the website IP. If you use ipipgo's Dynamic Residential IP, it's like wearing an invisibility cloak for your computer:

• Changing the "armor" (IP address) for each download.
• Breaking through a website's anti-crawler mechanism
• Rotate servers in different regions

Before I tried to continuously download the ten years of data of 300 companies, the ordinary method takes two days, with ipipgo proxy IP half a day to get it done.

Practical operation guide (with code)

Here's a useful script for the guys using Python+ipipgo:

import requests
from itertools import cycle

 List of proxies from the ipipgo backend
proxies = [
    "http://user:pass@gateway.ipipgo.com:30001",
    "http://user:pass@gateway.ipipgo.com:30002".
    "http://user:pass@gateway.ipipgo.com:30003"
]
proxy_pool = cycle(proxies)

def download_stock_data(url).
    for _ in range(3): retry 3 times
        current_proxy = next(proxy_pool)
        try: current_proxy = next(proxy_pool)
            current_proxy = next(proxy_pool) try: response = requests.get(url,
                proxies={"http": current_proxy},
                timeout=10)
            return response.content
        except.
            continue
    return None
