GBPJPY Bullish trend reversal

After failing to create lower lows in the pre-existing downtrend, the GBPJPY price action has now produced a bullish break-out on the 4 Hour timeframe, surpassing the previous high, thus confirming the start of a possible uptrend.
The previous downtrend has failed to continue creating lower bottoms and could signal the start of a new bullish trend reversal. A rally in price, surpassing the previous top created at the 153.00 level has confirmed the reversal in trend and can we expect the bulls to take full control, creating higher tops and higher bottoms.
The MACD has moved above its zero-line and continues moving further into positive territory, confirming the bullish trend direction and indicates that this bullish momentum is accelerating. The slope of the MACD histogram is on the incline, as well as moving above its 9-period moving average, once again confirming the sentiment of market participants.
An intraday break above the downtrend line, also confirms the weakened downtrend, while a close above the trendline will become more significant.
If this bullish price momentum continues, we could expect to find possible resistance zones in the form of 153.72 and 154.82 as per Fibonacci retracement levels 1.618% and 2.618% respectively.
In an alternative scenario, if sellers manage to regain the previous downward pressure, we could find price action revert back down to find support at the previous top around the 153.00 zone, before trying to break below the previous bottom at 151.94.
Summarized, if price action and bullish momentum continues to accelerate higher, we could see this currency pair print higher highs, continuing on its newly found upward path.
