The next days will be decisive for USDMXN now that NAFTA talks have officially begun. In the chart there are 4 relevant price levels (shown in bold green). And 2 short-term price levels (in thin red).
If the price breaks the short-term resistance at 18.04 then we would likely see the price reaching 18.40 or even 19.28 if NAFTA negotiations don't favor Mexico.
If the price breaks the short-term support at 17.48 then we may expect the price to reach the Pre-Trump support level at at 17.16.
Events that would favor the first scenario would be:
A full withdrawal from the NAFTA deal.
While the second scenario would be more likely in the event of:
A soft NAFTA "tweak".
An increased feeling of a "Trump's failed agenda".
An armed conflict between the US and North Korea.
