USD/MXN COULD BE IN A BULLISH TRIANGLE

In spite of oil, it does not want to go strongly up, looking at 4 hour charts, so I am thinking this is legg B in a wave 4. Eventhough, the legg is not over yet so it could go to 18.75 or even 19.00 said in last publication.

But since it is getting choppy I will place a stop @ 18.30 and still setting the target @ 19.00
