This idea is based on a trend line and price channel which is supported by the daily candle wicks and if we distance ourselves and look at weekly/monthly charts patterns we can see double bottom formed: October 2016 and March 2020
I also believe USD is weakening while GBP is getting stronger after Brexit, hence my predictions but never forget to place the stop loss (advised below the shaded resistance level) and treat this idea as just an idea not a trading advise! Protect your capital
