AUD/NZD 4 hour possible trend reversal

We're following this pair for a possibility of a significant momentum shift to the downside. We're looking at a confluence of significant long term resistance zone, coupled with bearish divergence on the RSI. We're looking for technical confirmation in the form of a breakout, breaking the ascending price trend-line or the 50 area RSI support zone should signal a short for us, aiming to hold for an extended move downwards, which in reality is reasonable since the fundamentals don't seem to support the pair breaking much higher.
