AUDCAD: Possible Buy Opportunity

There are following reasons to think about opening long positions:
- the price is going to bounce from 0.89000 support level
- the price dropped below the Bollinger Band, and it will move back
- the deep downward movement, which should be corrected
- we can get a possible reversal candlestick pattern.

The market gives us buy opportunity based on the daily chart, but buy signals it will be better to use from hourly timeframes.
