I have to agree with Spectra...
12 - 2 PM in YM can be very boring and generally non-productive. But like a good trader, I don't walk away (for the entire time). FWIW, it is during this time, and this time only, I use an indicator (a very fast ATR applied on a fast tf) in attempt to capture the mood AS the action returns.
The last 15 - 30 minutes of the day, nope. Not unless, as Spectra says, something juicy.
