Article 50 Trigger to compound a short term correction in USD?

٢٤ مارس ٢٠١٧

technically GBPUSD set to drop back to 1.21 add the fundamentals with article 50 triggering next week on the 29th, will we see a sell off in GBP in anticipation of what may happen.
DX short term correction for me will add more downside to this trade, nice R:R
