Nice idea on GBPAUD and there may be bullish potential as you have identified. We went for a longer time frame in our set up. The 1st support that we have identified is at 1.8016. It is a 50% Fibonacci retracement , 61.8% Fibonacci extension and a horizontal swing low support. Stochastic is approaching its support at 2.6% where a corresponding bounce could occur. If a potential bounce does occur, we may want to look at 1.8143 resistance level. It is a horizontal swing high resistance. Looking forward to see how things develop.
Please have a look at our idea and we would like to hear your thoughts.
