Hello everyone, I want to start this by saying I know absolutely nothing about options. I asked Gemini AI to code me a python program that scans the entirety of the S&P 500, and looks for Unusual Options Activity. I wanted to see if this data was valid, and should be taken into serious consideration, or how it could be improved. Here is the data it provided for the 10 stocks with the most unusual options activity.
