Why do I need a proxy IP for stock market data?
We do data collection know that those financial websites are more strict than thieves to prevent crawlers. Last month, a buddy with his own broadband to catch three days of data, the result of the IP directly blocked to the year 2099. This time we have to rely on proxy IP toDiversification of risk, as if fighting a guerrilla war, shooting one shot and changing places.
Let's take a real example: a quantitative team has to monitor 30 stock pages, and if they access them with a single IP, they will be blocked every 5 minutes on average. After switching to a proxy IP pool, it can be accessed viaRotation of residential IPs in different areas, hardening the collection success rate from 231 TP3T to 981 TP3T.
Practical Program Design (Hands-On Version)
Here's a breakdown for you guys.Four-step program::
A chestnut in Python.
import requests
from itertools import cycle
List of proxies from ipipgo
proxy_pool = cycle([
"http://user:pass@gateway.ipipgo.com:30001",
"http://user:pass@gateway.ipipgo.com:30002", ...
... More proxy nodes
])
def fetch_stock_data(url).
for _ in range(3): retry 3 times
proxy = next(proxy_pool)
try.
resp = requests.get(url, proxies={"http": proxy}, timeout=10)
return resp.json()
except Exception as e.
print(f"{proxy} is down, move to the next one")
return None
Here's the key point.Dynamic Switching + Failure Retrymechanism, like playing a game to renew your life. Here's a recommendation to use ipipgo'sDynamic Residential PackageIt's $7+ for 1 G of traffic which is enough to run for half a month.
A Guide to Avoiding the Pit (Blood and Tears)
Three major potholes that newbies tend to step into:
| pothole | Overturning Symptoms | method settle an issue |
|---|---|---|
| Poor IP quality | I just connected and got blocked. | Choose a residential IP over a server room IP |
| Too many requests | Trigger Frequency Limit | Plus random delay (0.5-3 seconds) |
| Protocol mismatch | Connection timeout | Confirming whether a website uses HTTP or HTTPS |
Special note: ipipgo'sTK LineIt works wonders for some brokerage websites. Previously, a private equity client used this program, and the data latency was 0.8 seconds faster than the counterparts.
QA time (heartfelt words)
Q: Why do you recommend residential IP?
A: The IP segment of the engine room has been memorized by major websites in a small book, and the residential IP looks like a real person's operation, and the camouflage effect is directly pulled full.
Q: How many IPs per day is enough?
A: 50 IPs/day is enough to turn around if ordinary retail investors monitor 10 stocks. If it is institutional level demand, it is recommended to go on ipipgo'sCorporate Packages, $9+ 1G with exclusive access.
Q: What should I do if my IP is blocked?
A: Immediately change the new IP don't hesitate, ipipgo's API extraction interface supports second replacement, which is at least 20 times faster than changing IP manually.
How to choose a package without wasting money
A direct comparison table is more intuitive:
| Package Type | Applicable Scenarios | price of item |
|---|---|---|
| Dynamic residential (standard) | Individuals/small teams | 7.67 Yuan/GB |
| Dynamic Residential (Business) | Institutional level requirements | 9.47 Yuan/GB |
| Static homes | Long-term monitoring of specific areas | 35RMB/IP |
Tip: Newbies are advised to buy firstDynamic Standard EditionTest the waters and upgrade when you get a feel for your own data volume. ipipgo supports switching packages at any time, which is much better than the rigid providers.
A final word of caution: data collection should be doneLegal Compliance, don't catch a website and glean it to death. Setting a reasonable collection frequency is not only a respect for the data source, but also a necessary operation to avoid legal risks. When you encounter difficult problems, you can directly find ipipgo's technical brother, they can help customize the collection strategy, which is much more worrying than blindly figuring it out by yourself.
