At the beginning of the baseball season I started playing a bunch of systems, same ones Frank is playing in another thread. They were doing great but then all of a sudden most all of the systems hit a cold streak. Now they are down nearly 100 units (after being up nearly 100 units a few weeks ago), so I pretty much quit using those systems. If they rebound I may start picking them up for a while and give them another chance, but for now I will just be handicapping. Sure it requires more time and thought than a mechanical system, but it sure has provided better results so far this season! What I am trying to tell you is it would be wise to not lay all of your eggs in one basket, rather diversify them as best you can.
