Wave counting analysis:During the November 20 trading session, the GBP / USD currency pair lost about 70 basis points, but still leaves no hope of building an ascending wave c. As part of this supposed wave, waves 1 and 2 can already be traced. Thus, if the current wave counting is correct, then the rise is resumed within wave 3, C, with targets located around 30 figures. As before, disappointing news on the Brexit talks or the refusal of the British Parliament to accept exit from the EU offered by Theresa May can hinder the growth of the pound.The objectives for the option with purchases:1.2991 - 38.2% of Fibonacci1.3175 - 0.0% of FibonacciThe objectives for the option with sales:1.2695 - 100.0% of Fibonacci1.2637 - 261.8% of Fibonacci (senior grid)General conclusions and trading recommendations:The GBP / USD currency pair remains in the process of building an upward set of waves, but the wave marking, if successfully attempted to break through the 100.0% of the Fibonacci level, will require making adjustments. The chances of building an ascending wave C with targets located near the marks of 1.2991 and 1.3175 remain, but a lot will depend on the nature of the news from the UK, which will come in the coming days.
