Johnson Outdoors Inc (JOUT) - student project

Hello! 
First of all, I really liked your classes as your teaching style is simple and starts with the basics - perfect for a beginner like me.
Now, the reason I chose JOUT was that its fundamental indicators were close to what you had talked about and the technical indicators like the candlesticks showed that now would be a good time to buy the shares as the opening rate is relatively low. 
Although, I couldn't understand the "P's" on the graph. Are these the different buyers and sellers who affect the price of the shares?
Also, how do I study the moving averages in this case?

Hope I didn't do really terrible for my first time. I will be looking forward to hearing from you on the same. Thank you!
