When financial data interfaces meet IP blocking? Try this wildcard
The old iron engaged in quantitative trading understand that the data interface is not moving to the wind. Last month just used Python to write the automatic trading strategy, these two days suddenly shut down. Check half a day and found that the IP was pulled by the data platform black - this kind of thing is just like the stock market encounter meltdown, anxious people scratching their ears.
That's when it's time toResidential IP ProxyCome to the jungle to save the day. Ordinary server room IP is like a cabbage in the supermarket, the data platform can recognize it with a glance. The residential IP is equivalent to the home-grown vegetables mixed in the stalls in the vegetable market, with the smoke and fire of the real home network, the data platform can't tell whether you are the Li Kui or the Li Ghost.
Why do quants love the SOCKS5 protocol?
Anyone who has played with proxies knows the difference between HTTP and SOCKS5, like a manual and an automatic. Financial data transmission to beSilky smooth without laggingThe SOCKS5 protocol can penetrate directly into the TCP/UDP layer, picking up two less layers of skin than the HTTP proxy. Specifically there are three brushes:
| functionality | SOCKS5 | HTTP |
|---|---|---|
| transmission speed | Akihabara | morning rush hour traffic jam |
| Protocol Support | All protocols accepted | HTTP only |
| authentication | double doors with safety deposit | Single thin anti-theft lock |
Take ipipgo's residential SOCKS5 agent that supports theUsername + PasswordDouble authentication is much more reliable than those pheasant agents who just take any IP and use it. Especially when doing high-frequency trading, dropping out once could be missing a couple of small targets.
Financial level agents have to go through five hurdles to get to the top of the list
Choosing a proxy IP can't be like picking carrots in a vegetable market, it has to be based on hard metrics of quantitative trading:
- IP purityYou have to have a decent home broadband, not those server room IPs.
- Geographical coverage: something like ipipgo that cuts to 240+ countries, so you don't get caught out when tuning the interface.
- responsiveness: Delay of more than 200ms directly pass, trading signals are more time-consuming than takeaways!
- concurrency: at least carry a triple-digit number of concurrent requests, don't get on your knees at the first sign of volume
There is a U.S. stock arbitrage buddy told me, before using other agents always at 10:00 a.m. EST on time to drop the chain, and then switched to ipipgo's dynamic residential IP, and finally with the gang of Wall Street hard line.
A practical guide to avoiding pitfalls (with code snippets)
Here's a real example of a Python call to a data interface using ipipgo's SOCKS5 proxy:
import requests
proxies = {
'http': 'socks5://user:pass@gateway.ipipgo.net:1080',
'https': 'socks5://user:pass@gateway.ipipgo.net:1080'
}
response = requests.get('https://api.finance.com/real-time', proxies=proxies, timeout=10)
Be careful to set thetimeout parameterDon't let the program wait for you. If the interface returns 429 error code, don't be hard-headed, just cut the IP when it's time to cut the IP. ipipgo's API can automatically change the IP, which is less troublesome than writing your own rotation script.
Quick questions and answers for veteran drivers
Q: How can I prevent my IP from being blocked by the data platform?
A: three tips: 1) use dynamic residential IP pool, do not catch an IP to death with 2) control the frequency of requests, do not get like a DDoS attack 3) remember to bring User-Agent, do not run naked on the battlefield!
Q: What about the high latency of the domestic data interface?
A: ipipgo'slocal relay serverIs the key, their family has access points in New York, London, Tokyo. For example, if you tune the US interface, you should choose the US West node, which is at least 30% faster than the direct connection
Q: How do I mess up if I need to call multiple data sources at the same time?
A: On the multi-threaded + IP pool combo. Make ipipgo's 90 million IP resources into a rotating pool, each thread randomly take IPs from different regions, remember to do a good job of IP health checks
In the end, choose the right proxy IP is like looking for a partner, light pretty useless, the key must be able to carry things. Those who do not move on the drop, delay agent, throw into the blacklist before it is too late. Professional things or have to hand over to ipipgo this old geezer, after all, people in the hands of the global residential IP resources, which is the bottom of the quantitative trading.
