Alright... update... Cleared 25% of position at 1.5560 on a 30-min "weakness" signal and cleared a further 50% at the end of the hour at 1.5579.
A price projection was at 1.5547 so I guess the bull's won this one. :(
Still holding a 25% short position until the end of the 2 hour signal completely closes out all my positions on this pair.
