Hello I'm experienced Python developer and I have strong expertise in building web scrapers. I've checked you script and found several point that we have to discuss in order to create the scraper more effective. Let's discuss it in detail over the chat. Regards, Alex.

Hi there, I took a glance at the code. It's really clear and looks good. However, it's not obvious how many symbols it's going to track which will directly effect the performance. The reason is that unfortunately selenium is not thread safe. For parallel operations and multithreading, you need to spawn several selenium instances and put each one into its own thread. But this way RAM and CPU usage will increase linearly as the number of symbols to track increase. To get the better of both worlds you need to create a queue system and spawn a certain number of instances which will constantly dequeue the symbols, update the price and/or tradingview where another component schedules the symbols to be processed again by putting back to queue. I did create a similar system in c# and it was definitely not fun so if you have a better alternative in mind we should go for that. Still, if the number of symbols to track is low, e.g 10 or something, and since you need 1 update every 30sec. for each symbol that means 1 update every 3sec. which can be handled with a single instance just fine. In this case, above is a total overkill since a single instance will do and please ignore my bid if so, thanks.

‌Hi, I have gone through your requirement to scrape lots of websites. I am EXPERT in building scraping tools /scripts. Hence, I can SURELY work on your project. I am having 4 YEARS of EXPERIENCE in developing PHP-PYTHON (Scrapy, Selenium) based web scraper as well as WINDOWS BASED web scraping software through which I have crawled many sites such as Craigslist, Amazon, Yelp and many others. I have also worked on complex site to bypass CAPTCHA with the use of PROXY IP bouncing techniques.. Let's work together :) Have a great day! I am glad to see your WORK HISTORY and positive reviews of other freelancers. I am really excited to work with you and would love to have a long-term business association for any of your data related needs less ,,,,,,

Dear, we are Team of French + US. I checked your project description, I can scrap your data. I will focus on user friendly interface. As you can see I have very good rate, you can be sure I am serious. Regards, Fabrice

Hello! I am a python developer. I looked at your project and it seems interesting. I have all necessary skills required for this project. Ping me to discuss in detail.

Hi, I'm not applying for the project, I simply wanted to have a talk with a fellow trader. I'm curious to hear about your work process and share some ideas and thoughts about strategies and tools. Hope to hear from you, Andy

I believe I am the best candidate for this project as for my experience in selenium. However, instead of using technologies that are operating system limited, I would prefer to use ones that are not. Also, I have not yet done the research to see why you have chosen to use selenium + proxies + user-agents to scrape tradingview. I have an inkling, however, as I am sure you are aware, they do have an api, and I would be inclined to use this rather than selenium. If you would like me to scrape rather than use an api I would be happy to do so. Thank you for your time and consideration. Cody Quist
