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

FX:GBPUSD   British Pound / U.S. Dollar
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
