According to the last entry, the British Pound performed as expected. The current rebound from the upward channel trendline level gives us a positive impulse for further increases. We can assume reaching the designated resistance, breaking it and further increases.
However, if the rate was to drop, the alternative option indicates where we should take into account short positions (hint: after breaking the levels indicated in the image, during correction). The possible adjustments shown in the image are hypothetical, and they do not have to be exactly the same, but after breaking one of the levels, the price has a chance to reach the designated price levels, making a correction.
