It's been a while that price has been moving into a rising channel, developing a correction after a sharp impulse to the down. What we may now see at the daily chart of GBPUSD is that price has reached the upper parallel of the channel and in addition the upper quartile of the median line, which has previously acted as both support and resistance. Any sell setup completion at current level might be the beginning of the upcoming next impulse to the down, which most definately want to catch as early as possible.
