Later on the Consumer Price Index (CPI) will be announced at GMT 12:30, so it is likely that volatility will subside until then.

Today the USDJPY broke above the high of the previous day shortly after GMT 00:00, and by GMT 04:00 it was trading in the vicinity of 156.40. Looking at the 1-hour chart of the USDJPY (as of GMT 04:00 on May 14), yesterday's breakout has abruptly shifted the market into an upward trend, and the price is now band-walking.

Today the USDJPY started trading by opening a downward gap of about 10 pips, but the price soon rose to fill this. A little after GMT 01:00 it seesawed violently, hitting a low of 155.50 yen.

Today the USDJPY began rising in the morning session, hitting a high of 155.77 not long before midday. Looking at the 1-hour chart of the USDJPY (as of GMT 03:20 on May 10), the Bollinger Bands are not expanding and the middle line is more or less flat, from which one can conclude that the market lacks a sense of direction going forward.

Today the USDJPY fluctuated in the 155-yen range without much sense of direction. On Tuesday and Wednesday the price rose from the Tokyo session and reached new highs, but so far today it has been unable to do so and the high is unchanged. Looking at the 1-hour chart of the USDJPY (as of GMT 05:25 on May 9), the upward momentum has been lost and the upper and lower Bollinger Bands are tightening.

Today the USDJPY continued to trend upward, in the process moving the battleground to the 155-yen range, as shown by the high of 155.26 it reached just after GMT 02:00. Looking at the 1-hour chart of the USDJPY (as of GMT 15:20 on May 8), the middle line of the Bollinger Bands is rising, and the price continues to move above that level.

Today the USDJPY started trading at 153.88, rose during the morning session, and reached a high of 154.58 after GMT 02:00. Looking at the 1-hour chart of the USDJPY (as of GMT 04:20 on May 7), the price has bounced off the middle line and broken through the upper 2 standard deviation band.

Today the USDJPY began trending upward directly after trading commenced, and just before GMT 04:00 it hit a high of 153.97 yen. Looking at the 1-hour chart of the USDJPY (as of GMT 03:55 on May 6), the price reverses into a rising trend after hitting the -2 standard deviation Bollinger Band.

Continuing its downward trend in today's Tokyo session, the USDJPY fell through the low of the previous day and marked a low of 152.75 yen shortly after GMT 02:00.

Today, the USDJPY rose as it recovered from yesterday's sharp price decline, and a little while past GMT 01:30 it had regained the 156-yen level. Looking at the 1-hour chart of the USDJPY (as of GMT 03:35 on May 2), it can be seen that the market has retraced from the early-morning plunge in the price.

In the first half of today's Tokyo session, the USDJPY continued its leisurely rise in an extension of the previous day's trend. As of GMT 03:00, it had hit a high of 157.89 yen, putting the 158-yen level within reach if it continues on this trajectory.

Today the USDJPY opened at 156.33 before rising gradually to hit a high of 157.00 between GMT 01:00 and GMT 02:00. Looking at the 1-hour chart of the USDJPY (as of GMT 03:05 on April 30), the level where the price broke below the -2 standard deviation Bollinger Band several times has become a floor, and the price is now moving slowly upward.

Today the USDJPY started trading by gapping down by around 50 pips at the open, but this was quickly filled and the price subsequently continued to rise.

As today was the second day of the Bank of Japan's Monetary Policy Meeting there was an announcement regarding the benchmark rate, but as expected there was no further hike. The USDJPY soared in response, breaking through the 156-yen level.

Today again the USDJPY remained at the high end of its range with no clear trend, and after GMT 05:00 fluctuations in the price were restricted to the extraordinarily narrow limits of 154.73-154.87 yen.

Today the USDJPY started trading at 154.83 yen, and some time after GMT 01:00 it reached a low of 154.65.

Today the USDJPY fell directly after the open to touch a low of 154.41 yen, after which it rose to hit a high of 154.73 a little before GMT 01:00.

At around GMT 01:00, there were news reports of a large explosion within Iran, and from the middle of the 154-yen range the USDJPY plunged as far as 153.58. The situation was subsequently further complicated by news that there had after all been no major explosion on the Iranian side caused by an attack by Israel.

Today the USDJPY opened at 154.33. Not long after GMT 02:00 the price fell below the recent low, going down as far as 153.95, but it recovered immediately and resumed trading in the 154-yen range.
