Why you should prepare yourself to sell AUDJPY?

When it comes to trading, patterns play an important. While analyzing for patterns, I came across this one. In my view, if the pair breaks the channel, it will go down. For safety reasons, it is not recommended to trade this pair until it breaks down and make a flag, pennant, or retest to the breaking point.
Please note that this is not a trading signal or a trading call. This is just an idea came across my mind.
Thank you and trade safely
