AAPL by the Hour

I've been collecting intraday minute data for over a month. Here's a quick set of graphs showing the gain/loss for every hour throughout the day (the first half hour considered an hour by itself). The images are named in PST.

I doubt much can be gleaned from this alone. On average the 7am hour has been the best play for a long, the 9am hour (lunch? in NY) is the best hour to sit, and the last hour is the best to go short. The largest standard deviation in values is in the 7am hour, followed by the 6am half hour.
