U.S. Socks5|New York Stock Exchange high-frequency API calling program

How the U.S. Socks5 agent to solve the New York Stock Exchange API high-frequency call problem

Recently, a friend who does quantitative trading of U.S. stocks approached me to complain, saying that the strategy system developed by their team is always restricted by the New York Stock Exchange API to limit the number of requests. This is actually quite common in the financial circle, especially the main high-frequency trading, or will be officially pulled into the dark room. Today we will talk about how to use the proxy IP to break this situation.

Why is the Socks5 protocol better suited for high-frequency calls?

Let's start with a real case: last year, a private equity with HTTP proxy to engage in API calls, the results of continuous triggering of the wind control mechanism, the account was almost frozen. The problem lies in the HTTP protocol features are too obvious, the exchange monitoring system can be recognized in minutes.

That's when it's time toSocks5 ProxyOn to the show. This thing has three great tricks:

Four Steps to Real-World Configuration

Here's an example of ipipgo's Residential Proxy in hand to show you how to deploy it:

1. Created in the ipipgo backendDynamic residential agent poolSelect U.S. Node
2. Configure the authentication method (recommended whitelisting IP binding)
3. Set the proxy parameters in the code:

   proxies = {
       'http': 'socks5://user:pass@gateway.ipipgo.com:24000',
       'https': 'socks5://user:pass@gateway.ipipgo.com:24000'
   }

4. Add a middleware that automatically switches IPs, it is recommended to change them every 5-10 minutes

High Frequency Calling Anti-Blocking Essentials

Don't think that everything will be fine if you hang up your agent, these are a few pits you should avoid:

• Don't use the data center IP(The exchange loves to block these.)
• The frequency of requests from a single IP is controlled toWithin 30 beats per minute
• Remember to simulate normal user behavior and add a random 0.5-2 second delay
• Update 1/3 of the IP pool every week (ipipgo's auto-refresh feature works just fine)

Frequently Asked Questions QA

Q: Why is it better to use ipipgo's proxy than to build my own server?
A: Self-built IPs are easily recognized as server room IPs. ipipgo's residential proxies are real home broadband, and the trading system is more difficult to detect.

Q: What should I do if I encounter slow API response?
A: First check the proxy delay, ipipgo background has a real-time speed measurement tool. If individual nodes have high latency, manually switch service areas in the console.

Q: How to handle the need to call multiple exchange APIs at the same time?
A: It is recommended to create multiple proxy sub-accounts and assign independent IP segments to each exchange. ipipgo supports the separation of sub-account privileges for easy management.

Finally, a cold knowledge: the New York Stock Exchange's API wind control system at 3:00 a.m. (U.S. Eastern Time) will reset some of the counters, a reasonable arrangement of the call time can be twice as effective.
