EURGBP broke out of its descending resistance-turned-support line where a potential bounce on weakness at 0.8696 (76.4% Fibonacci retracement, multiple swing low support) could occur. This could push prices all the way to its resistance at 0.8789 (38.2% Fibonacci retracement, horizontal swing high resistance).
RSI (89) has a corresponding breakout from its descending line which contributes to our bullish bias.
