In the past few months the falling price of the Euro has caught the attention of all market professionals that follow the financial markets. From its high of over 1.60 in July of 2008 against the United State dollar, the Euro is now barely above the 1.20 level. The fall of the currency has been due because of the debt issue facing Greece, Spain, Portugal, and a few other European Union nations. Recently the Euro has been holding steady in a trading range between 1.24 and 1.21 versus the U.S Dollar.

It will be up to the politicians of the European Union nations and the International Monetary Fund to come up with solid plan to help out the debt laden nations with their financial problems. If the IMF and other E.U. countries cannot come up with a plan, the Euro does risk falling further against the U.S Dollar and other all major currencies. With many of these E.U. nations needing financial support from their neighbors, consequently the Euro Dollar has become weaker. The weaker Euro has had a positive correlation with the Chinese Solar stocks. Both the Euro and the Chinese solar sector have been moving in the same direction over the past few months. However as the solar companies continue to make profits; their stock should rise before the Euro.

Major Chinese solar stocks including: LDK Solar Co. Inc. (LDK), Suntech Power Holding Co Ltd. (STP), and Yingli Green Energy Holding Co Ltd. (YGE) have all been trading lower as the Euro has dropped. The Euro Dollar began its trend lower beginning around December of 2009; the Chinese solar stocks soon began trading lower, following the Euro, in January of 2010. Investors can see the correlation that the solar stocks and the Euro have by using forex charting software and learn to trade forex with the charts of the various Chinese Solar companies.

Some charting software will allow the investor to overlap one chart on top of the other. This will show the positive correlation that both the currency and stock price have. Suntech Power Holdings Co. reported its earnings on June 3^rd 2010, included was a loss of $24.5 million due in part because of the depreciating Euro Dollar against the U.S. Dollar. Even though Suntech’s profits jumped almost ten times to $20.7 million from $2.1 million in the year ago period, investors and market professionals were still concerned about the Euro and the issues with the European markets going forward. The stock made a small move upward, but has since fallen back in its range near the 52 week low of $9.05 a share.

All the Chinese solar stocks have fallen back party due to in part because the equities market has been in a mild correction. LDK was also able to reported higher sales and better gross margins. Revenues rose to $347.6 million from $282.3 million in the year ago period. The company was also forecasting full year revenues of between $1.6 and $1.7 billion. Even with the impressive revenue numbers, LDK Solars’ stock price is still hovering around the 52 week low of $5.06 a share. Again this is somewhat due to the unsteady market conditions, related to debt problems occurring in the E.U. The same situation is also occurring with YGE Holding Co. The company is still currently trading near the lows of the past few months, after experiencing a selloff during the month of May.

At the moment there is a clear positive correlation between the Euro Dollar and the Chinese solar stocks, I do not see it lasting into the future. The revenues and profits being generated by the Chinese solar companies are improving year over year. Solar power as an energy source is gaining popularity as a way to produce energy for cities or towns. The solar stocks have been under significant pressure for the past month and are due to bounce back. The decline in the Euro has hurt these companies financially; however it should only amount to a small percentage of future revenues going forward. The increased revenues that the Chinese solar companies are reporting this year, and the revenue projections for next year, will minimize the losses from exchange rate issues. When the Euro starts to rebound on good news from the European Union, Chinese solar stocks will make a strong recovery.

Simple Moving Average

Most technical analysts use the Simple Moving Average, or the arithmetic mean.

A simple Moving Average adds up prices in its time frame and divides the sum by the width of the time frame. For example, for a 20-day simple MA of closing prices, add up closing prices for the past 20 days and divide the sum by 20. However, there are a few criticisms about the simple MA such that:

1)      Each price affects a simple MA twice—once when it comes in and another when it drops out.

2)      Only the days in the time frame that the average is based on are taken into account (for example, the last 20 days)

3)      It gives equal weight to each day’s price. The last day’s price receives the same weight as the first day’s price, which some analysts believe that there should be a heavier weight on the more recent data instead.

Exponential Moving Average

An Exponential Moving Average (EMA) helps overcome these criticisms. It assigns greater weight on the more recent data. It does not drop old prices from its time window, but rather, they slowly fade out after time.

Few people calculate indicators by hand these days since computers can do the calculations much faster and more accurately. But if you are interested in knowing how to do the calculation yourself, here it is:

EMA = P_today* K + Ema_yesterday * (1-K), where
- K = 2/(N+1)
- N = the number of days in the EMA (chosen by trader)
- P_today = today’s closing price
- EMA_yesterday = Yesterday’s EMA

How does Moving Average Work?

The most important part of a moving average is the direction of its slope.

-When the EMA rises and slopes up, trade the market from the long side.

-When the EMA falls and slopes down, trade the market from the short side.

-When an EMA starts constantly sloping up and down, it signals a trendless market and you are recommended to stop using trend-following methods until a new trend emerges.

EMA works in all timeframes but the best in weeklies, where it helps you stay better with the major trend. Therefore, many traders prefer trading in the direction of a weekly moving average.

Trading Techniques

When the prices move above MA, it is a buy signal.
When the prices move below MA, it is a sell signal.

When we buy near the moving average, we are maximizing our gains and minimizing our risks. The same rule applies to shorting in downtrends, where you are better off shorting near the EMA.

You can also use dual moving averages to identify trends and entry positions. For example, you can use the longer EMA to identify the trend, and the shorter EMA to find entry positions.  Moving averages in general help identify trends, decide whether it is better to trade long or short, and give us hints on when to enter a trade. To find exit points, we can use channels.

Moving average is a trend-following indicator and is one of the oldest, simplest, and most useful tools for traders. Whereas chart analysis is subjective and difficult to test, moving average signals are objective, precise, and not open to debate. Its purpose is to help traders identify if a new trend has started or if an old trend has ended, generating specific buy and sell signals. Moving averages are represented by lines plotted on price charts, each point reflecting the latest average price. In general, they reflect the average consensus of value at a specific period of time.

A moving average adds new prices as they occur, while dropping old ones. A rising moving average shows that the market is becoming more bullish, signaling you to stay long. A falling moving average shows that the crowd is becoming more bearish, signaling you to hold shorts.

• Which data should I average?

Traders who use daily and weekly charts usually apply moving averages to closing prices. However, the construction of moving averages should be whatever works best for you. You can even add the Closing price + High + Low of each bar and divide the result by three, if you feel that this works better for you. Some people prefer to use a midpoint value, which is the result when you divide the day’s range in half.

• How long should I set the Moving Average?

After you construct the data that you will be using, you also need to choose the width of your time window:

1) Longer Averages (Slower)

• Catch longer trends
• Advantage:  Have smoother moving averages
• Disadvantage:  Responds to trend changes slower, can miss important reversals

2) Shorter averages (Faster)

• Catch minor trends
• Advantage: Tracks prices better; able to signal trends earlier in the move
• Disadvantage: Its average is more sensitive to trend changes and the more sensitive it is, the more likely it is to pick random “noise” and produce false signals or deviations from the main trend, also known as whipsaws.

The longer time frames work better as long as the trend continues, but a shorter average is better to use when the trend is reversing. Nevertheless, make sure you test whatever width you choose to use on your own set of data.

Rectangles are usually continuation patterns but you still have to be alert for signals of a reversal pattern.

Rectangles enable traders to trade the swings within the pattern, buying dips and selling rallies. They take about 1-3 months to form and complete.

1. First, there is a sharp market move, resembling almost a straight line (flagpole) on heavy volume.
2. Prices pause for 1-3 weeks on light volume, forming a consolidation pattern.
3. Prices break out and the trend resumes in the direction prior to the flag or pennant on heavy volume.

Both patterns usually appear in the middle of a market move and, therefore, the move after the flag or pennant will travel the same distance of the move preceding the pattern.

The Flag

The flag is shown below, indicated by 2 parallel trendlines in the shape of a parallelogram, which tends to slope against the trend.

The Pennant

The pennant is shown below, indicated by 2 converging trendlines, resembling a symmetrical triangle.

EMA = Ptoday* K + Emayesterday * (1-K), where
- K = 2/(N+1)
- N = the number of days in the EMA
- Ptoday = today’s closing price
- Emayesterday = yesterday’s Ema

Trading Signal:
- A buy signal is triggered when closing prices cross above the EMA.
- A sell signal is triggered when closing prices cross below the EMA.

Example:
Let’s look at the stock charts of Apple and Citigroup as examples. A buy signal is generated when prices cross above the 9 day EMA, as circled below. A sell signal is generated when prices cross below the 9 day EMA.

How Do We Calculate Simple Moving Average?
A simple moving average is calculated by computing the average closing price of a security over a specified number of periods. For example, a 10-day moving average is calculated by adding the closing price for the last 10 days and dividing the result by 10. 1+2+3+4+5+6+7+8+9+10=55, 55/10 = 5.5 (Assuming that the closing prices for the 10 days are 1-10 consecutively). When you plot the moving average for each date on a graph, it forms a curve.

Trading Signals:
- A buy signal is triggered when closing prices cross above the moving average (MA).
- A sell signal is triggered when closing prices cross below the moving average (MA).

Example:
Let’s look at the stock charts for MSFT and YGE as an example. A buy signal is generated when prices cross above the 10 day moving average  as circled in 1, 2, 3. A sell signal is generated when price crosses below the 10 day moving average.

Disadvantage:
The main disadvantage of a  simple moving average is that it does not reflect the current trend quickly. For example, if the stock prices in the last 10 days for a certain stock were 100, 99, 98, 45, 44, 45, 43, 42, 43, 42, the simple moving average would be 60.1. This moving average is 50% above the current price which wouldn’t be accurate to trigger an entry signal. In other words, if there is an extreme high or extreme low in the stock price, it distorts the true value of the stock. For this reason, another type of moving average called exponential moving average (EMA) was developed, giving more weight to the most recent prices.

Triangles usually represent continuation patterns. A triangle is a congestion area where resistance, forming the upper boundary, and support, forming the lower boundary, converge on the right. The triangle’s upper boundary represents sellers overpowering buyers, preventing the market from rising. Its lower boundary represents buyers overpowering sellers, preventing the market from declining. As the two boundaries start to converge, a breakout forms.

There are 3 types of triangles:

1) Symmetrical Triangles-

- A fair balance of power between bulls and bears. Both are equally confident since bulls keep paying up and bears keep selling lower.
- Represented by the convergence of an ascending support line and a descending resistance line.
- The breakout is likely to resume in the direction of the trend that preceded the formation of the triangle.

2) Ascending Triangles
- These triangles are bullish patterns, with a flat upper boundary and a rising lower boundary, converging on the right.
- The flat boundary shows that bulls are becoming more aggressive while bears are losing their ability to drive down the prices. Bears are defending the line that they’ve drawn, but if they collapse and the attacking bulls succeed, its breakout is likely to be steep.
- An ascending triangle is more likely to result in an upside breakout, thus the logic of buying upside breakouts from ascending triangles is derived.

3) Descending Triangles
- These triangles are bearish patterns, with a flat lower boundary and a declining upper boundary converging on the right.
- The flat boundary shows that bears are becoming more aggressive while bulls are losing their ability to drive up the prices. Bulls are defending the line that they’ve drawn, but if they collapse and the attacking bears succeed, its break is likely to be sharp.
- A descending triangle is more likely to result in a downside breakout, thus the logic of shorting downside breakouts from descending triangles is derived.

Broadening Formation (Inverted Triangle)

This inverted triangle is basically a triangle turned backwards and is relatively rare. Instead of trendlines converging at the right, the trendlines actually diverge in a broadening formation. It is also known as a megaphone top.This type of pattern usually occurs at major tops and is usually a bearish formation.

MORE ABOUT TRIANGLES

There are two main price patterns:

1) Reversal Patterns- Indicates that the trend will reverse. A few of the most common reversal patterns include:

a. Head and shoulders

b. Double tops and bottoms

c. Triple tops and bottoms

2) Continuation Patterns- The trend pauses for awhile but it resumes. A few of the most common continuation patterns include:

a. Triangles (1), Triangles (2)

b. Rectangles (Coming Soon!)

c. Flags and Pennants (Coming Soon!)

The triple top or bottom is another reversal pattern, which rarely occurs. It is a stronger pattern than the double top or bottom pattern since the likelihood of a reversal is higher.

The triple top or bottom pattern is a slight variation of the head and shoulders pattern. The main difference is that in a triple top, the three peaks are around the same level, whereas in a head and shoulders pattern, the head is at a slightly higher peak than both of the shoulders.

• Triple Top Pattern
  

A triple top pattern is complete after both troughs have been broken on heavy volume. Prices must close below the support levels to complete a triple top pattern, signaling the reversal to a new downtrend. There might also be a return move to the breakout point, but should not exceed it, before the downtrend resumes.

Volume

Similar to volume in the presence of a head and shoulders pattern, volume during a triple top pattern tends to decline at each subsequent peak, but increases at the breakdown point, leading to the new downtrend.

• Triple Bottom Pattern

As you can see, a triple bottom pattern is a mirror image of the triple top.

A triple bottom pattern is complete after both peaks have been broken on heavy volume. Prices must close above the resistance levels to complete a triple bottom pattern, signaling the reversal to a new uptrend. There might also be a return move to the breakout point, but should not decline below it, before the uptrend resumes.

Volume

Similar to volume in the presence of a head and shoulders pattern, volume during a triple bottom pattern tends to decline at each subsequent bottom, but increases at the breakout point, leading to the new uptrend.

Example:

As you can see from the example below, the stock WMGI just formed a triple bottom pattern. After reaching its 3rd bottom at about $13.75 per share, it rallied up to $16.50. That’s a 20% gain!
