If they ease...
The big question will be "if they ease" and they have a tough decision. The trend in sentiment has been swinging that way, and perhaps the weak US data might encourage the RBA to get ahead of the curve, but on the other hand is the concerns about the housing prices. If housing gains does not slow that can be more detrimental if there is a burst of the bubble at some point.
So it is a more of a gamble.
Having said that traders can prepare for the after the event trade.
Technically, the pair is looking more bullish. The price moved above topside channel trend line. On Friday it closed above a downward sloping trend line on the 4 hour chart and the 50% retracement of the move down from the February 3 high. That level comes in at 1.4312 level currently. That line will be a key level to stay above if the buyers are to remain in control. If that line is broken (likely on the back of the RBA remaining as is and expressing increasing concerns about the house prices), then there should be further momentum selling.
Looking at the daily chart (see chart below), there is some pretty significant levels that are being approached. The first is the 200 day MA (green line in the chart below). That level comes in at the 1.44138 level.
The next level is the 61.8 of the move down from the February 3rd high at the 1.44489. This level is also near the high from March 2nd (see 4 hour chart above).
The third key level is the 100 day MA (blue line in the daily chart below). That level currently comes in at the 1.4466 level.
This combination not only should provide selling levels before the release for those looking to trade the pair. If the RBA does cut, they will provide the road map for further upside. The price of the EURAUD would need to get and stay above these levels to keep the bulls firmly in control.
Can EUR bullishness help the pair? Of course and if the EURUSD can keep the upside momentum moving higher on Monday, that may lead to the test of some of the topside targets, but by Tuesday, the focus will switch to the decision, and then I feel the focus on the pair will be dictated by what the decision is.
That will be a gamble. I don't like gambling, but the levels are there to trade after the event and details are known.
