Trend is bullish in USD/JPY currency pair in 15 minutes time frame. short term support could be seen around the 121.99 price level. In last few trading days, market has printed a bearish corrective Wave 4 leg. Now, I expect price to resume the up trend and I am waiting for a bullish break out in price, out of bearish trend channel. Current price action offers a possible buy trading chance to join the up trend. However; a break down in price below 121.99 vital support level will fail the bullish forecast. In such case I will stay out of the market and re-analyze the price action of USD/JPY currency pair.
