FWIW I have looked at the non-farm payroll days results for the past 13 months (not a huge sample I know) for the JonnyT type break out system & GBP, 70 pip stop. At first glance results don't seem to be anything out of the ordinary ie -38, -22, NT, +56, -70, +54, +70, +103, -70, NT, -70, NT, NT and today NT. Bearing in mind that this is with a 2 hour time restriction on entry, so often the markets may be waiting for the news release and nothing much happens early on. An all day entry study would be more interesting (will post later), as would FOMC meetings etc.
