Pound Yen began to rise, but for how long?

Approaching the 50% retracement level means the possibility of a decline in a downtrend on a four hour timeframe with a key level at 152.6. The older timeframe shows an uptrend and therefore the current decline is a correction within it, and the prospect of growth to 153.9 and above 155.15 will be alive if the price does not fall below the June minimum of 151.32
