GBP/AUD Buy Entry

We are focusing GBP/AUD for buying is beacuse, first the AUD Currency Index is at its Resistance, and AUD has conquered the Top Flight for the past 2 weeks and I think it will fall with just a slip. Second, it is at the furthers support and it is also a D1 Support, so that the STOP LOSS will not be a big deal since it is a -30pips STOP LOSS. Kind of Risky since the Selling Momentum is still Strong, but this Selling Momentum has been strong for the past weeks. Third, the graph is creating a double bottom.
