With the BOJ decision to maintian the current Yen interest rate, the rebound of the Aussie could continue to 89.300 before a bearish retreat to 84.400. At the moment the bears still hold the market under the 50 day MA on the daily.
The alternative to the upside would be a break above 89.500 for a bullish move to 89.800 conservatively, should the Aussie continue to strengthen. Manage your risk smartly.
