Halifax HPI is about to be released.
As GBPUSD shows not much power of going too far either up or down I would be interested in long position on good UK news, however I would not expect much more than 1.6160.
In case of bad news I would trade short only when price would go below today low, however it would have to be clear that it's not just a stop loss hunting. To be safe I would wait price to bounce back to 1min bollinger band and then entry short.
