Reliable way to get market close of all US stocks using PolygonIO

I like to help out beginning traders but this sounds like it's something else. likely this is commercial or you have been hired to create this screener. I feel it is unethical to request community support for such things. Others may feel differently. Good luck.

I understand your point.
At this point this is not a commercial project.
But, to be honest, I'd like to think it could become one day, if it works fine and is helpful in trading.
The tool is aimed to guide a trader because I would be too afraid it passes orders and a bug make me loose everything.

I am not hired.
My field is computer graphics, not finance.
 
If you don’t have any coding knowledge, you can get in touch with a coder who can help you build your own system that works like this. If you try doing it manually, you may not be able to make the right decisions.

I agree. A coder would be able to help translate this into an algorithm.
