Hi! I am new to quantconnect and am trying to create a simple algorithm that will buy all stocks that gapped down overnight at the beginning of each day, and then sell them at the end of each trading day. I created a universe for for the volume and price criteria (the price must be between 1 and 100 USD, and the 10 day SMA of the volume must be greater than 3,500,000). I keep getting errors, then tweaking my code and getting more errors. If anyone can help me figuring out what I am doing wrong it would be greatly appreciated. I'm not sure if I have completely on the wrong track and am wasting my time, or if I just have a few simple errors that I'm overlooking. Thanks in advance!
