2018 starts with the continuation of the signals triggered in the middle of December and confirmed in the last week of the 2017, right after Christmas. GBP/USD defended the long-term up trendline and bounced from the horizontal support on the 1.331. After that the price broke the upper line of the wedge, which actually triggered a buy signal here. The potential target is around the tops from September.
If we are talking about GBP, let's stay in UK and analyse the FTSE index. Here we have a classical ascending triangle pattern, which resulted in a bullish breakout of the horizontal resistance. 2018 brings us a nice buy signal here.
FTSE is doing great, DAX not so much. Here, buyers have the last chance to keep the buy signal alive. We are on the long-term up trendline and on the lower line of the flag. In addition to this we still have a chance to defend the 12900 support (sharp reversal creating a hammer candlestick). In this situation hammer would be a strong buy signal. On the other hand, breakout can be lethal, with a creation of a major sell signal.
