On the above images the box is created between 00:00 am to 7:00 am EST on GBPUSD M15 chart. On a neat reaction of the market like the one below (Aug 4, 2006) you can even place your order with peace of mind about 15 minutes before the news release. BTW, if you want to win big I suggest to focus on GBPUSD only (just a suggestion).
