EUR/USD, GBP/USD are heading lower while AUD/USD and NZD/USD have given back their earlier gains.

(Note the pops for AUD and NZD were not large).

On Globerx, overnight CME trade, S&P500 index futures have dropped - extending their Thursday US time losses. NQ also dropping.

Apart from what has been posted there is no fresh catalyst I can see. I don't see a need for a fresh catalyst for the ES and NQ drops, continuation moves.
