Stock Market Dataset: Residential Proxy Access to Financial Data

When Stockholders Meet Anti-Crawlers: Alternative Uses of Residential Proxies

Recently, a quantitative trading friend complained to me that the crawler program he wrote was always blocked by the IP of the financial website, and he tried all kinds of disguise means, and even his own broadband was blocked for three days. This reminds me of the experience of helping a private equity organization to do data collection last year -Access to financial data is essentially a war of offense and defenseThe

Why does your crawler always get pulled?

Many newbies will ignore the anti-climbing mechanism of the site. To cite a real case: a stock forum set the"Auto-blocking for more than 20 visits per minute from the same IP address".The rules. Bulk accessing with a server room IP is like holding up your ID card and going to the bank counter to repeatedly access $1. If you don't block you, who will?

Hands-on: grabbing stock comments with ipipgo

Taking a well-known stock community as an example, we achieve stable collection through ipipgo's residential proxy. The focus is onSimulate real user behavior::

import requests
from time import sleep
import random

proxies = {
    'http': 'http://user:pass@gateway.ipipgo.com:9021',
    'https': 'http://user:pass@gateway.ipipgo.com:9021'
}

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0) AppleWebKit/537.36'
}

for page in range(1,100): url = f'{page}'.
    url = f'https://stock.site/comments?page={page}'
    response = requests.get(url, headers=headers, proxies=proxies, timeout=10)
     Randomly wait 3-8 seconds
    sleep(random.uniform(3,8))
     Processing data...

Key Tip:

• Change User-Agent per request (don't use the fake_useragent library)
• 在代码里加入随机，别用固定sleep值
• Don't fight with CAPTCHA, change IP and continue

Guide to avoiding pitfalls: these details kill people

1. Don't use requests.: The session object maintains a TCP connection and is easily recognized.
2. proxy pool should be large enough: it is recommended to use ipipgo's dynamic residential proxy, their IP pool is automatically updated every hour
3. Pay attention to request header fingerprints: in particular, Accept-Language and Cookie settings
4. Dealing with redirection traps: some sites will intentionally return 302 jumps to detect crawlers

QA: Trouble you may be having

Q: What should I do if the agent is too slow?
A: Preferred ipipgo'sHigh Speed Residential Agent Package，他们的节点有专门优化过TCP连接速度，实测能控制在200ms以内。

Q: What if I need to collect overseas stock data?

A: This means that your behavioral characteristics are recognized. Try adding mouse movement track simulation to the crawler, or switch to ipipgo'sDevice Fingerprint BindingFunction.

put at the end

Financial data collection is like dancing in a minefield. Last year, a private equity firm was claimed 2 million dollars by a website because the IP of the server room was captured. It is recommended that newbies buy ready-made proxy services directly from ipipgo, their home"Failure Retry + Auto Switch"Mechanisms can save a lot of work. Remember, good tools are half the battle, the remaining half depends on whether you will pretend to be 'normal'.
