UsdJpy- New high is probable on medium term

After making a high around 112 at the beginning of July, UsdJpy has started to drop.
The drop is clearly corrective in nature and is contained in a flag pattern.
2 days ago a bullish engulfing candlestick pattern has formed and this can be an indication of a bottom.
I;m bullish as long as the price is above 108.75 and buy dips is my strategy
