Financial Instrument Characteristics

Hello fellow FF members!

One of the most important things when developing trading methods and strategies is knowledge about the environment one is trade in. To widen our knowledge and possibly realize something new, I would like to propose a discussion about financial instrument characteristics. How could we map out the trading environment?
