A newbie question points on support resistance calculations

[Igat]

OK so far today trading Euro/USD I calculated my support resistance points based on the usual high low close. So far I am up 50 pips however my concern is for tomorrows figures. Due to the interest rate cut in the US the Euro surged 100+ pips and came back down again, the simple question is in my calculations for tomorrow is this is it safe to assume this high as part of the calculation? Thanks in advance

I would say most rules have gone out the window in the last couple of weeks. Assume nothing...
