The above chart is of the E-Mini Futures. You would have no way of knowing that. I would sell every time the price hit the top bands and buy when it hit the lower band. Like anything else in the market, there are no guarantees.
I don't find myself eating because I'm bored anymore. I find that I want to eat only very small portions. The only thing that has been difficult is getting used to my new appetite. I've been throwing out a lot of my food because I physically feel like I cannot eat that much, and if I do eat too much then I don't feel so good. However, I'm learning to keep all my meals small and frequent (just like I should have been doing all along!).
