Since April 2018, the US dollar has been gaining a lot against the GBP with about 2000pips. Despite several instances of oversold positions, price still continued to go lower until support level was reached in December 2018 at 1.24797. A correction started when price touched the resistance level in February 2019 at level 1.33460. Thereafter, a pullback occurred.
The trendlines have been broken to the downside. RSI shows at two different instances this year that $GBPUSD has been overbought. Before the correction in the price of $GBPUSD, it hit the middle line of the Bollinger bands. Though the candlesticks are still in the higher region of the bands, a reversal could begin, which might make price cross to the lower region of the bands. Price has low tendencies of breaking out of the resistance level 1.33406 upward. About 1000pips could favour the USD against the GBP in the next few weeks. As $GBPUSD might begin a bearish trend, it could reach the support level.
