AUD had been weak last few days, and AUDCAD broke out of bullish trendline. Currently, price is retracing back role reversal area, possibly forming head and shoulder pattern. I'd go into smaller TF and look for selling opportunity.
On 4hr, price seems bullish at the moment, making sequence of HH and HL. If price action consolidate around TL, I'd consider going short somewhere between role reversal and WM3 confluence level.
