I've made the decision to move the stop to B/E given the uncertainty over the AUD rate decision which gets released at 3:30am London time.
Marc Chandler, Chief Market Strategist at Bannockburn Global Forex wrote - "In Bloomberg's survey 21 of 24 economists surveyed expect a 25 bp rate hike. The futures market is less confident. It shows slightly more than a 50% chance"
In addition to the futures market pricing, we've only seen two example this year where rates were raised on the expectation of a rise, with February resulting in a ~100 pip drop and March resulting in a ~100 pip gain. Other examples of rises had positive affects on the AUD, but none of them were forecast.
So a difficult decision to make because I think the trade setup is A+, but you can't get married to it and there is enough data pointing to at the very least some volatility, and at worse severe downside.
