The Fed meeting tonight and BOE tomorrow practically guarantee high volatility on GBPUSD. But this also could mean that our abovementioned 1.3150 - 1.33 area will be reached, even if only for a brief moment. That could be the opportunity to go short.
Of course, the current rally could also reverse before it reaches 1.3150. Especially if the outcome of the Fed meeting tonight is remarkably hawkish, that could quickly send GBPUSD down to 1.30.
Still, the safer approach (first scenario) is to wait for GBPUSD to reach 1.3150 - 1.33 and then look for reversal signals/patterns on intraday timeframes such as 1H and 4H, which could provide the signal to enter short. Now, exactly at what level such a reversal happens is hard to say ahead of the Fed and BOE meetings as the next 24 hours could get very volatile in
GBPUSD, and a big spike up or down wouldn’t be a surprise.
The other scenario (e.g., if Fed is hawkish and BOE dovish) would have GBPUSD continue down below 1.30 without touching at least 1.3150. In this case, entering short on a break below 1.30 would be an appropriate approach, targeting 1.2850.
Importantly, in the larger context, the outlook for GBPUSD is bearish. The break below 1.3150 on the weekly chart indicates that GBPUSD should eventually break below 1.30 as well. The first target to the downside is the 1.2850 zone.
