The Sterling was also benefit from Dollar bearish after FOMC yesterday, topped at 1.6596 and closed at 1.6555. Technically on h4 chart below we can see that my triangle has been violated to the upside indicating potential further bullish scenario at least towards 1.6700 area before re-testing 1.7042. Immediate support at 1.6520/00 area. Break below that area should lead us into no trading zone but I prefer bullish scenario at this phase.
On fundamental side, investors focus is now on whether the BoE is going to expand the quantitative easing program. If that happen, Sterling should be under heavy pressure and technical bullishness might fail.
