GbpUsd is bullish, but where to buy it?

Two days ago, GbpUsd broke violently above 1.3 zone resistance. After a rapid rise to 1.3177, the pair is falling now and is coming to confirm 1.3 zone as new support.
The long term trend for Gbp is bullish and a reversal up from 1.3 zone would confirm that cable resumed its long term direction.
On the other hand, a dive back under 1.3 would put GbpUsd in no men's land
