DOUBLE BOTTOMS


An Intraday Double Bottom In USD/JPY

A positive divergence between the MACD indicator and the greenback/yen pair provides an intraday buying opportunity.

Security:   USD/JPY
Position:   N/A

The combination of volatility and leverage makes trading the Japanese yen more than a little intimidating than trading many other common, international currencies. While it is true that currencies in general trend better than most other trading vehicles, the Japanese yen is often an outlier on that trend of trendiness. Arguably, and particularly of late, the level of intervention the Japanese central bank has exerted in the currency markets has contributed greatly to the volatility of that nation's currency.

That said, the volatility in the Japanese yen can be less of a problem in shorter-time frames, such as hourly charts, when short-term trends can develop, mature and end in the context of what might appear on a daily chart to be merely the sort of high-intensity zig-zagging that is more common to polygraph tests of guilty suspects than of instruments prudent traders would feel comfortable associating with.

Figure 1: Compare the two troughs in the USD/JPY at approximately 9:35 and 12:30 to the troughs in the MACD at the same time. This positive divergence led prices higher and anticipated a successful breakout above 118.50 by 14:00 (2:00 p.m.)

Here, I was watching the USD/JPY as it made a lower trough near mid-day Eastern time. One entry set-up that I have been using as a tool for studying intraday forex is Dave Landry's 2/20 EMA breakout system, which he presented in Technical Analysis of Stocks and Commodities magazine back in December 1996. Essentially, Landry's system looks for confirmation (by way of a follow-through bar) of a breakout based on price action around the 20-period exponential moving average. Whether or not a trader decides to actually use the 2/20 EMA breakout as a trading system, the 2/20 EMA breakout system is helpful at a minimum in determining when new trends appear to be developing.

What caught my eye, however, was the positive MACD divergence after the USD/JPY made a lower low. Recall that a positive divergence comes when an indicator points toward a bullish development, while price action remains bearish. In this instance, the fact that the second MACD trough was higher than the first one sets up a positive divergence compared to the two troughs in the USD/JPY, which show a lower low in the second trough. A Landry 2/20 EMA breakout occurs shortly after prices rebound from the second trough and the rally is on.


Figure 2: After reaching its price projection level of 118.80 near the bottom of the 15:00 hour (around 3:30 p.m.), the USD/JPY reversed and fell sharply back toward the breakout level around 118.50.

This is also an example of how combining technical strategies can help make winning trades. Landry's 2/20 EMA breakout would have a trader long near 118.45, but the trader would not necessarily know whether or not it made sense to take quick profits as USD/JPY approached resistance just north of 118.50 or to stick it out for larger gains. The combination of the double bottom and the positive MACD divergence would have signaled that there was likely more upside beyond 118.50. In fact, the double bottom anticipated a move to the 118.80 area -- given the 30 pip size of the formation and a breakout level at roughly 118.50. As Figure 2 shows, this projection was exactly correct, as prices touched 118.80 briefly before correcting sharply.
