Proxy Submission

To scrape currency rates, you can use various financial data sources that provide reliable and up-to-date exchange rate information. However, keep in mind that scraping financial data may be subject to the terms of service of the respective websites, and it's crucial to comply with their policies.

Here are some legitimate alternatives to scraping:

1. Use a Financial Data API: Many financial data providers offer APIs that provide real-time and historical exchange rate data. Examples include:

   • Open Exchange Rates
   • ExchangeRate-API
   • Alpha Vantage

   These services often require an API key, and they may have free and paid plans with different levels of access.

2. Central Banks and Financial Authorities: Some central banks and financial authorities publish exchange rate information on their official websites. For example, the European Central Bank (ECB) provides daily updated exchange rates.

3. Financial News Websites: Financial news websites often display live exchange rates. You can check websites like Bloomberg, Reuters, or CNBC.

Remember to always check the terms of service and licensing agreements of any data provider you choose to use. Using a legitimate API is generally more reliable and ensures that you're accessing accurate and authorized data.

Avoid scraping from websites that explicitly prohibit scraping or do not provide permission for such activities. Unauthorized scraping may violate terms of service and legal agreements.

In Selenium, you can check if the DOM of a page is loaded by using JavaScriptExecutor. Here's how you can check:

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("http://www.example.com")

while True:
    try:
        driver.execute_script("return document.readyState")
        if driver.execute_script("return document.readyState") == "complete":
            print("Page is loaded")
            break
    except Exception as e:
        print("Exception occurred")

In this script, the document.readyState property is used to check if the page is loaded or not. In JavaScript, the "complete" value of document.readyState indicates that the page is loaded.

This script will keep running until the page is loaded. Once the page is loaded, it will print "Page is loaded" and break the loop.

Please note that this script assumes that the page is completely loaded when document.readyState is "complete". However, this is not always the case. Sometimes, some elements may still be loading even when document.readyState is "complete". So, it's better to use explicit or implicit waits to wait for specific elements to be present or visible.

Rotary proxies are proxies that cyclically change their real IP address. This is used to make it harder to track their location. The port usually changes as well. How this happens depends on the software used on the proxy server.

Before activating a proxy server in Opera, it is recommended that you clear your browsing history and cookies of sites. This is necessary to ensure that information about the computer is not transmitted during further connections. To do this, it is enough to follow the algorithm:

Open the browser.
Click on the opera icon in the upper left corner.
Hover your mouse cursor over the "History" item.
Use the option "Clear history of visits".
After that you need to specify parameters of the proxy server. To do this, perform the following actions:

Open your browser.
Click on the Opera icon in the top left corner.
Click on "Settings".
Select the "Advanced" option.
Scroll down to the "System" tab.
Click on "Open proxy settings for computer".
Click on "Network settings".
Activate the "Use a proxy server" option.
In the window that opens, specify the IP address of the proxy server. Enter the address in the field of the protocol to which the proxy server belongs. You can get this information from your provider.
Click "OK" to save your settings.

An "open" proxy means one that is publicly available. It can be used by many network users at the same time. But because of this its bandwidth is also quite low, because the server simultaneously handles all requests through a single port.
