But I am more into number crunching & arbitrage than long term data analysis... More risk more reward. You are young. Might as well do it now before you get settled down with a wife and kids. Then you will see how much more risk they add to your trades. First build capital, Then preserve it.
have you done much with behavioral economics yet? This is a powerful field and is probably the leading factor in most markets. "Don't worry about figuring out where the herd is going, as much as leading them to where you want to go."
