Stock Market Dataset CSV Download: Historical Market Data Packs

Why do you always get stuck with stock data downloads?

Recently, the old Zhang wanted to get some U.S. stock historical data to do analysis, the results found that many sites under a csv file is more difficult than the sky. Either limit the number of downloads or directly block the IP, what is even more annoying is that some platforms see the domestic IP directly blocked. At this time if there is a reliable proxy IP tool at hand, it is really a relief.

How can proxy IPs help you sneak through the data barrier?

As a chestnut, suppose you want to download ten years of daily data from a financial platform in bulk. Ordinary operation may be down to the 5th time on the IP blocked. With ipipgo's proxy IP service, each request for a different export IP, the site can not distinguish between a real person or a machine in the operation. The specific operation is like this:

import requests
from ipipgo import RotatingProxy

proxy = RotatingProxy(api_key='your key')
url = 'https://xxx.com/historical-data.csv'

for page in range(1, 50):: {'https' = {'http', 'http')
    proxies = {'http': proxy.get_next()}
    response = requests.get(url, proxies=proxies)
     Save the data locally...

In this code snippet, theRotatingProxyIt will automatically rotate IPs in different regions, perfectly circumventing the access restrictions of a single IP. Remember to set reasonable request intervals, don't mess up their servers.

What are the doors to look for when choosing a proxy IP?

特别注意有些免费代理号称高速稳定，实际用起来上千毫秒都是常事。之前用ipipgo的香港金融节点测试，下载速度能稳定在2MB/s，比自家宽带还快。

Configuration guide that even a novice can handle

1. Go to the official website of ipipgo to register for an account, new users get 1G traffic trial
2. Generate the API key in the console
3. Selection of specialized packages for financial data collection (with ⭐ marker)
4. Refer to the documentation to configure the proxy parameters
5. It is recommended to take a small batch of data to test, stabilize and then run the full amount of

Focusing on step 3.Don't go for the regular package.! Financial websites have stricter wind control and have to use specially optimized IP pools. Before a buddy to cheap with ordinary package, the results of half an hour to be recognized.

Old driver common overturn scene QA

Q: Why are you still blocked even though you have changed your IP?
A: 80% of cookies or device fingerprints are not processed. It is recommended to randomly generate User-Agent for each request with ipipgo's browser fingerprint protection.

Q: What should I do if I get disconnected halfway through the download?
A: ipipgo support for continuous transmission, in the code to add a retry mechanism on the line. It is recommended to set up a maximum of 3 retries with an interval of 10 seconds.

Q: Which node should I choose to place NYSE data?
A：优先选美国东海岸的金融专线，能控制在150ms以内。别迷信物理距离，有些西海岸节点反而绕路了。

Don't step on these potholes!

1. Don't write a dead IP address in the code, use an automatic rotation mechanism
2. Remember to clean up the connection after downloading to prevent the IP from being dragged to death.
3. Remember to check the important data to prevent downloading the defective files.
4. Early morning collection is not necessarily safer, it depends on the quality of the IP.
5. Don't be tough when it comes to CAPTCHA, and don't be reluctant to go to a coding platform.

The last nagging sentence, now a lot of data platforms are on the intelligent wind control, just change the IP is not enough to see. It is recommended to match the ipipgoTraffic camouflage modelIt can disguise your collection request as normal browser behavior, which is tested to effectively circumvent 90%'s wind control interception.
