In previous articles about connecting to exchanges for data, I ran my setup on a foreign server without network issues. However, since most people run locally and need proxies, I explored the considerations for using proxies locally. To fetch data without an API key, you can directly specify the proxy when initializing the exchange instance, like this: ```python exchange = ccxt.binance({ 'timeout': 60000, 'proxies': { 'http': '127.0.0.1:7890', 'https': '127.0.0.1:7890', } }) exchange.load_markets() ``` I used Clash as my proxy software, which defaults to port 7890. Other proxy software can be researched or found within the application. For trading operations, Binance requires an IP whitelist. Without your own server, you can only whitelist the IP of the purchased node, which poses some risk. It's safer to run on your own server. You can check your proxy node's IP at https://ipinfo.io/. While it's not advisable to run quantitative programs on purchased nodes, experimenting with small accounts during the learning phase is acceptable.

In my previous articles about connecting to exchanges to obtain data, I didn't have to worry about network issues since I was running it directly on the foreign server I purchased. However, considering that most people are still running it locally and need to use proxies, I recently took some time to try out the precautions for using proxies locally.

First, if you only need to obtain data, you can do it without an apiKey, just specify the proxy directly and initialize the exchange instance with the proxies field:

exchange = ccxt.binance({
   'timeout': 60000,
   'proxies': {
      'http': '127.0.0.1:7890',
      'https': '127.0.0.1:7890',
   }
})
exchange.load_markets()

The proxy software I use is clash, and the proxy port defaults to 7890.

You can search for other proxy software on your own, or you should be able to find it within the software. If it's some closed-source software, it might be a bit difficult to find, and you may have to capture packets to see.

For operations like trading, Binance requires setting an IP whitelist. If you don't have your own server, you can only set it to the IP of the purchased node, which might carry some risk, I think. It's still safer to run it on your own server.

However, for safety's sake, I still do not recommend using purchased airport nodes to run quantitative programs. But during the learning phase, using a small fund account for experiments is still acceptable.
