The upward momentum for GBPUSD D1 continued strongly with the sixth consecutive day of gains last Friday. Friday's up D1 bar was structurally important because it broke out - from the most recent price high, confirming GBPUSD D1 return to the uptrend, as it established a new price high.
GBPUSD H1 accelerated as it created an upward sloping price channel with a steeper slope than the trend line below. This increased buying pressure is a sign of a trend with strong momentum that is likely to continue. So if GBPUSD H1 pulls back today, you can wait to buy.
