Tests overhead resistance in early trading
The USDMXN is off to a bullish start as President Trump and Mexican President Nieto agree to disagree.  
Technically, the pair moved up to the 100 hour MA in NY trading yesterday and backed off. The pair is back up testing that MA in trading now. That MA comes in at 21.32250. The price did trade above for a brief moment but backed off. A break above will be eyed for more bullish sentiment. In the meantime traders are leaning as risk is defined and limited.
