It was the deep of illiquid night when the momentum ignition trading algos struck. Out of the blue, a liftathon in all JPY crosses without any accompanying news sent the all important ES leading EURJPY surging by 50 pips, which in turn sent both the Nikkei up over 1% in minutes, and led to an E-Mini futures melt up of just about 8 points just when everyone was going to sleep. All of this happened completely independent of the actual data, which was chiefly European retail sales which missed (-0.6%, Exp. 0.4%, prior revised lower to 0.5%), Eurozone Service PMI which dropped (from 52.2 to 51.6) but beat expectations of 50.9 (notably the Spanish Service PMI of 49.6, up from 49.0 saw its employment index drop from 46.5 to 45.3, the lowest print since June), and finally, German Factory Orders which surged from last month's -0.3% to +3.3% in September. And while all this impacted the EUR modestly stronger, it had little if any residual effect on the ES. The bigger question is whether these slightly stronger than expected data point will offset the ECB's expected dovishness when Mario takes to the mic tomorrow).
