CCI: Commodity Channel Index

CCI is used to know when the asset is overbought and when it is oversold.


-          CCI = ( (TP-MA) / (0.015*MAD) )
-          MAD= Mean Absolute Deviation  
                                     |MAn – TP1| + |MAn – TP2| + …+|MAn – TPn|
                      MA: Moving Average                MA = (P1 + P2 + P3 + P4 +…. + Pn) / N
           TP : Typical Trice                   TP  = Asset Price

CCI = (Typical Price - 20 period SMA of TP) / (.015 x Mean Deviation)
Typical Price (TP) = (High + Low + Close)/3
Constant = .015
There are four steps to calculating the Mean Deviation. First, subtract
the most recent 20-period average of the typical price from each period's
typical price. Second, take the absolute values of these numbers. Third,
sum the absolute values. Fourth, divide by the total number of periods (20).


   Default CCI is normally set at 20 or 21 days, with overbought and oversold band levels set at 100 and -100.
   CCI designed by DONALD LAMBERT and measures a price and identifies how far away from a moving average it is extending, and how fast it moved to get there.
  When the CCI is at 0 the price is touching the moving average.
-          It helps to :
1-   Determine cyclical trends
2-   Identify potential peaks and valleys.
3-   Estimate changes in the direction of price movement.
4-   Find divergences that may lead to possible reversal moves.


1)   The CCI divergence or convergence can pick up the possibility of beginning of a correction.
2)   CCI is useful to identify overbought and oversold extremes, within ranges.
3)   It is designed to detect beginning and ending market trends.
4)   The conventional CCI trading system works as follows. When it rises above 100, buy and hold until CCI falls back below 100. When CCI falls below -100, sell short and cover the short when it rises above -100 line.
5)   An aggressive use of the CCI indicator dictates entering positions when the index crosses the 0 line.
6)   An opposite way to interpret CCI is: levels above 100 as overbought regions and bearish signals. And levels below -100 as oversold regions and bullish signals.
7)  High values show that prices are unusually high compared to average prices whereas low values indicate that prices are unusually low.
8)  On DONALD LAMBERT analysis:  if the CCI goes above the +100 line, that’s a signal to establish a long position. When the CCI drops below the +100 line the long position is closed out. The same techniques apply to short positions at the -100 line. Conduct no trading when the CCI is between -100 and +100.
9)  The original trading method produced too many trades and too few profits.
10)        Using longer periods for calculating the CCI gave better results than shorter periods.
11)         Using a CCI-zero crossover to initiate trades rather than breakouts above +100 or below -100 improved returns significantly.
12)         Rapid advancement of the CCI from zero to ±100 is typical of a strong trend under way.
13)        CCI-zero crossover, is a dangerous method and it is recommended to combine it with another indicator. CCI can be used in combination with J. Welles Wilder's directional movement index, the ADX.
14)        The CCI zero line often denotes an area of support / resistance. It offers points from which to draw trendlines.
15)        Watch price action when CCI breaks through a zero line that had been a support or resistance zone.
16)        A CCI-zero crossover is synonymous with prices crossing over the moving average of the same period, such as when a 40-period CCI crosses over the zero as price crosses over a 40-period moving average. It should be no surprise if prices find at least temporary support at this level. It is a good time to pay close attention to the market and bring in a stop. This price support may well give way to an appreciable retracement or even the next impulse move of the trend. If, however, the CCI-zero crossover or price-moving average crossover is subsequently confirmed, then this is a low-risk opportunity to add to a position or reestablish one.

The use of CCI:

Studies show that the CCI of longer durations reduce whipsaws and remain a leading or coincident indicator of price trend reversal. The index tracks every nuance of price change. If the peaks and troughs of the CCI outline are accurately matched with price peaks and troughs, then violations of the CCI trendlines are excellent timing alerts. Recommended CCI periods are 20 for monthly charts, 40 for weekly charts and 80 for daily charts. For intraday and short-term trading, an 80-period CCI for five-minute charts and a 40-period for hourly charts is recommended.


1)   CCI can be more effective in a market subject to cyclical patterns.
2)   It can generate a number of false signals.
Because of this CCI is often used as a secondary or confirming indicator.



 The relative strength index was created by J. WELLES WILDER JR in late 1970s. RSI is a momentum indicator that compares the price of a security relative to itself and relative to its past performance. The RSI is less volatile than the ROC, because the RSI takes the average of the up and down days, its results are less affected by a sharp dip or rise on a specific day. As a result, this method tends to be a more stable momentum indicator than the ROC calculation.

 RSI is a tool which can add a new dimension to chart Interpretation when plotted in conjunction with the original price chart. Some of these Interpretative factors are:

-           TOPS and BOTTOMS are indicated when the RSI goes above 70 or drops below 30.
-          CHART FORMATIONS which often show up graphically on the RSI may not be apparent on the bar chart
-           FAILURE SWINGS above 70 or below 30 on the RSI scale are strong indications of market reversals.
-          SUPPORT and RESISTANCE often show up clearly on the RSI before becoming apparent on the bar chart
-          DIVERGENCE between the RSI and price action on the chart is a very strong Indication that a market turning point is imminent.

The RSI is a Momentum Oscillator:

 The momentum oscillator measures the velocity of directional price movement. Note the Interaction of the oscillator curve and the price curve. The oscillator appears to be one step ahead of the price; the reason being that the oscillator, in effect, is measuring the rate of change of price movement.

How RSI is calculated?


For the first calculation of the Relative Strength Index, RSI, we need the previous 14 days close prices. From then on, we need only the previous day's data.

 The initial RSI is calculated as follows:

 (1) obtain the sum of the UP closes for the previous 14 days and divide this sum by 14. This is the average UP close.
 (2) Obtain the sum of the DOWN closes for the previous 14 days and divide this sum by 14. This is the average DOWN close.
(3) Divide the average UP close by the average DOWN close. This Is the Relative Strength (RS).
(4) Add 1.00 to the RS.
(5) Divide the result obtained in Step 4 into 100.
(6) Subtract the result obtained in Step 5 from 100. This is the first RSI.
    From this point on, it is only necessary to use the previous average UP close and the previous average DOWN close in the calculation of the next RSI. This procedure, which incorporates the dampening or smoothing factor into the equation, is as follows:
  - To obtain the next average UP close: Multiply the previous average UP close by 13, add to this amount today's UP close (if any) and divide the total by 14.
 - To obtain the next average DOWN close: Multiply the previous average DOWN close by 13, add to this amount today's DOWN close (If any) and divide the total by 14.
Steps (3), (4), (5) and (6) are the same as for the Initial RSI.

Why do I need to know this?

Platforms software do the whole work, and afford us the RSI and other thousands of indicators ready to use plot in the chart and manipulate easily. 
However, learning how such an indicator is calculated helps traders get a full understanding of how it works and what its signals mean.   

What the Relative Strength Index indicates?

Tops and Bottoms :

These are indicated when the Index goes above 70 or below 30.

The Index will usually top out or bottom out before the actual market top or bottom, giving an indication that a reversal or at least a significant reaction is Imminent.

Chart Formations:

 The Index will display graphic chart formations, which may not be obvious on the price chart. For instance, head and shoulders tops or bottoms, pennants or triangles often show up on the Index to indicate breakouts, and buy and sell points.

Failure Swings:

Failure swings above 70 or below 30 are very strong indications of

a market reversal. (See Fig. 6.3 and Fig. 6.4.)


Support and Resistance:

Areas of support and resistance often show up clearly on the Index before becoming apparent on the price chart. In fact, support and resistance lines drawn using index points are often analogous to trend lines drawn using bar or candlestick chart points.


Divergence between price action and the RSI is a very strong indicator of a market turning point. Divergence occurs when the RSI is increasing and the price movement is either flat or decreasing.
 Conversely. Divergence occurs when the RSI is decreasing and price movement is either flat or increasing.
A divergence signals a waning of momentum. It does not necessarily signify new momentum in the opposite direction. Divergences appear frequently in uptrends and downtrends in response to the tug-of-war between those trying to drive momentum further faster and those betting against it. Again, there are many divergences in a trending market, but only one of them will end up signaling the end of the trend.
As such, divergences are best thought of first and foremost as warnings to exit, and second as opportunities for a reversal.
Overbought or oversold conditions in a bull or bear market do not generate meaningfully reactions unless preceded by divergences.
One of the first signs of reversals is that a short-term oscillator reaches an extreme that has not been seen since the previous bear or bull market.

Famous mechanical RSI trades:

Ø  Equilibrium crossovers :   
                -    buy when above 50, sell when bellow.
Ø  Buyer only :
-          Entre long: RSI < 30 reversing towards the upward.
-          Close long: RSI > 70 reversing towards the downward.


The RSI is still a popular tool for spotting divergences and for warning traders of overbought and oversold conditions. The RSI has become less widely used for its ability to create chart patterns, and traders have since learned that overbought and oversold conditions do not in and of themselves indicate market tops and bottoms.
One way of thinking about the RSI is that it compares the bullishness of bullish sessions to the bearishness of bearish sessions, using points gained or lost as the gauge of “how bullish is bullish/how bearish is bearish.” That differs from the way the stochastic measures bullishness or bearishness, but in both instances the technical indicators are looking forward to determine which of the two forces, those betting on higher prices or those betting on lower prices, is in control of the market.

Dow Theory

dow theory

The Dow theory

It is perfectly evident, from the statements made by the contemporaries of Charles H. Dow, that he never intended, in the brief paragraphs which appeared in his Wall Street Journal editorials, to become the grandparent of technical studies. Perhaps if he had lived a little longer, the urging of his friends would have resulted in a more systematic presentation of his theories, from his own mind. As it is, what we know about Dow’s theories of stock price movements we learn chiefly from the writings of his contemporaries, and others who have taken up the work where they left off.”   
By H.M GARTLEY, Profits in The Stock Market.

Dow theory is the basis theory of technical analysis of financial markets first observed and developed by Charles H Dow through over 250 editorial in the wall street journal. Through a set of guidelines, Dow theory enables traders to identify the primary trend and ride its way.

Why we study the Dow Theory:

     - It is one of the oldest theories of technical analysis.
- The most widely publicized and followed theory of stock price movements.
- This theory, as shown by market action over many years, involves principles which are absolutely fundamental in price movement, and no trader can afford to be ignorant of them.  

Brief history

Before taking up the theory in detail, let us review briefly some general history of the men who have been responsible for bringing Dow’s theory to us.


He was born in New England in 1850. He served as a reporter on the Springfield Republican in his early years. Later he became a member of New York Stock Exchange, in partnership with Robert Goodbody.
In time, the partnership was dissolved and Dow returned to newspaper work. In 1889 he founded the Wall Street journal, and gained confidence of his readers in his efforts to report fairly and interpret without bias the financial news of the day. In his editorials Dow was always cautious in the extreme, and because of his reticence he never came out with a flat statement of his principles of technical market action.
Although he began keeping averages in 1884, he wrote practically nothing about his theory until 1901 and the first half of 1902, and then his discussions started in editorials devoted to general business conditions. Nevertheless, he was the first technical analyst of note.

S. A. Nelson:

He was the first person to speak of “Dow’s theory”. In 1903 he published a book called The A B C of stock speculation. Nelson had been a member of the Wall street Journal staff when William Peter Hamilton was a young reporter thereon.
 Nelson said in his preface that many requests had been received for a book giving the principles governing stock speculation, and if any man was qualified to write such a volume, that man was Charles H. Dow.
 But Dow died leaving only a few editorials. However, Nelson says that Dow’s theories are given in The A B C  of Stock Speculation, and acknowledges the assistance of Dow’s colleagues and contemporaries in preparing the book.
 Apparently, Nelson was on excellent terms with Dow and the book may be regarded as a reasonably authoritative summary of Dow’s theory as it was originally formulated.

William Peter Hamilton:

Hamilton was the editor of the Wall Street Journal from 1908 until his death in 1929. An Englishman by birth, he served in his early boyhood as a page on the floor of the London Stock Exchange. But he had a strong sense of adventure, and when Gold was discovered in south Africa, he joined the rush to these regions. 
After sometime spent as a trader in gold and diamonds in South Africa, Hamilton migrated to Australia and New Zealand, and then to The United States. Here he joined the staff of the Wall Street Journal, and was closely associated with Charles H. Dow during the closing years of the latter’s life. 
Beginning in 1903, Hamilton wrote editorials for the Wall Street Journal until his death in 1929. Some of these were on the subject of “the price movement”, and comprise most of his writings on the Dow Theory. These editorials aggregating some 260 in all. Have been collected by Robert Rhea and published as an appendix to his book The Dow Theory. Hamilton also published a Book entitled The Stock Market Barometer in 1922.
In fact, The Dow theory as generally understood was almost entirely the joint work of Dow and Hamilton. Dow had been reticent and cautious in his statements about price movements, but Hamilton became an ardent interpreter and exponent of the founder’s precepts. While he referred constantly to Dow’s methods, there is little question that Hamilton was constantly developing the Theory in his own mind.
Hamilton’s characteristics may best be summed up by saying that he was a journalist, not an analyst. His method of observation was impressionistic, not systematic.

Robert Rhea:

 The most prominent contemporary Dow Theorist, first became interested in the Dow Theory in 1910. He had a small retail automobile tire store in Colorado. His father, believing that good business men should keep themselves informed on economic conditions, subscribed to the wall Street Journal for him, and urged his son to read it thoroughly, especially the editorial column by William Peter Hamilton.
Rhea became interested in in Hamilton’s discussions of the price movement, and finally, in 1914 he started trading. His first venture in the market resulted in substantial profits, but he was soon to learn that he did not know enough about Dow’s Theory, for when the first bear market came, he lost a large part of his previous earnings. He promptly withdrew from the market, and started to study the theory.  After that, he rejoined the market, made handsome profits and became an ardent follower of Dow’s theory.  
In the summer of 1932, he began writing articles on the theory for Barron’s, and then he published his book The Dow Theory, in the same year.


Little background on averages:

It was not until May 26, 1886, that Dow Jones Industrial Average (DJIA) was born with 12 companies’ stocks. A year later, a separate average was started to keep track of the rail road stocks, DowJones transportation average. The Dowjones Utilities (DJUA) did not exist until 1929; the standard and poor’s 500 (S&P 500), not until 1957.

Principles of the DOW Theory.

Many traders, especially beginners, try to apply technical analysis without a fully grasp of the field.
Before applying the Dow Theory in practice, Charles Dow made some assumptions that are the main tenets of his way of analyzing financial markets.
Those principles are essential in order to apply the theory successfully.
Here is a summary of those principles, and what you need to know about them

1 - Manipulation:

Short term movements, from few minutes to few days, could be subject of manipulation by speculators and large institutions.
So, it is possible in daily movement and to a limited degree in secondary reaction. But the Primary trend can never be manipulated.

2 - Averages discount everything

Known also as “efficient market theory”. The market reflects all available information.
Everything there is to know is already reflected in the markets through the price.
You may notice sometimes that markets react negatively to good news. The reasoning behind that is by the time the news hits the street, it is already reflected in the price “priced in”.
This explains the old wall Street axiom “buy the rumor, sell the news”. As the rumor begins to filter down, buyers step in and bid the price up. By the time the news hits, the price has been bid up to fully reflect he news.
In stocks, the run up to earnings is a classic example.
In the Dow theory, the daily price fluctuations of the DowJones averages afford a composite view of all the hopes, disappointments and knowledge of every one who knows anything of financial matters. For the reason, the effects of coming events (excluding acts of God) are always properly anticipated in the dowjones index movement.

3 - Market Movements

A) – The three Market Movements

a-      Primary movement (Major bull /bear Market)
b-      Secondary movement(correction)
c-       Daily fluctuations (the ripples)

dow theory market movements

 Dow defined three types of price movements: Primary movement, secondary movements and daily fluctuations.
Primary moves last from a few months to many years and represent the broad underlying trend of the market; it is a long sustained directional move.
Secondary (or reaction) movements last from a few weeks to a few months and move counter the primary trend.
Daily fluctuations can move with or against the primary trend and last from a few hours to a few days.


Charles H Dow compared those market movements to movements of the ocean where there is a tide, waves, and minor ripples.
On January 31, 1991, he wrote in the Wall Street Journal:
“ A person watching the tide coming in and who wishes to know the exact spot which marks the high tide, sets a stick in the sand at the points reached by the incoming waves until the stick reaches a position where the waves do not come up to it, and finally recede enough to show that the tide has turned. This method holds good in watching and determining the flood tide of the stock market.”
There is a big wave (tide), known as the primary movement, that is made up of secondary waves of lesser amplitude and duration.
Similarly, the secondary wave is made up of minor waves of still smaller proportions.
Since it is by literally riding the wave that profits are made, the first task of a trader is to determine:

 a-       The direction of the Tide.
      b-      The stage of development of the wave.
 d-      The direction of the minor ripple.

B) Stages of Primary Movement

There are three stages to both primary bull and bear markets.
A primary bull market in stocks is defined as a long sustained advance marked by improving business conditions that elicit increased speculation and demand for stocks.
A primary bear market is defined as a long sustained decline marked by deteriorating business conditions and subsequent decrease in demand for stocks.
In both primary markets, there will be secondary movements that run counter the major trend.

Primary Bull Market:

Stage 1: accumulation

The first stage of a bull market is largely indistinguishable from the last reaction rally of a bear market. Pessimism, which was excessive at the end of the bear market, still reigns at the beginning of a bull market.
It is a period when the public is out of stocks, and the news are bad.
However, it is at this stage that smart money begins to accumulate stocks. Stocks are cheap, but nobody seems to want them.
In the first stage of a bull market, Price is undervalued (oversold) and starts to find a Bottom. When the market starts to rise, there is a widespread disbelief that a bull market has begun.
After the first leg peaks and starts to head back down, the bears come out proclaiming that the bear market is not over. It is at this stage that carful analysis is warranted to determine if the decline is a secondary movement ( a correction of the first leg up). If it is a secondary move, then the low forms above the previous low, a quiet period will ensue as the market firms and then an advance will begin. When the previous peak is surpassed, the beginning of the second leg and a primary bull market will be confirmed.

Stage 2: Big Move

The second stage of a primary bull market is usually the longest, and sees the largest advance in prices. It is a period marked by improving business conditions and increased valuations in stocks. Participation is broad and the trend followers begin to participate.

Stage 3: Excess

This stage is marked by excessive speculation and the appearance of inflationary pressures. The public is fully involved in the market, valuations are excessive and confidence is extraordinarily high.

Primary Bear Market:

Stage 1: Distribution

Distribution marks the beginning of a bear market. Market is overvalued, as the smart money begins to realize that business conditions are not quite good as once thought, they start to sell stocks.
Most investors and speculators are still involved in the market at this stage. There is little in the headlines to indicate a bear market is at hand, and general business conditions remain good.
However, stocks begin to lose a bit of their lusts and the decline begins to take hold.
When the market declines, there is little belief that a bear market has started and most forecasters remain bullish.
After a moderate decline, there is a reaction rally (secondary move) retraces a portion of the decline.
However, the reaction high of the secondary move would form and be lower than the previous high. After making a lower high, a break below the previous low would confirm that this was the second stage of a bear market.

Stage 2: Big Move

It provides the largest move. This is when the trend has been identified as down and business conditions begin to deteriorate. Earnings estimates are reduced, short falls occur, profit margins shrink and revenues fall. As business conditions worsen, the sell-off continues.

Stage 3: Despair

By the final stage of a bear market, all hope is lost and stocks are frowned upon. Valuations are low, but the selling continues as participants seek to sell no matter what. The news are bad, the economic outlook bleak and not a buyer is to be found. The market will continue to decline until all bad news is fully priced into stocks. Once stocks fully reflect the worst possible outcome, the cycle begins again.

dow theory accumulation and distribution movements

4 – Volume must confirm the trend

  Movements in volume should confirm price movement, otherwise we got false breakouts and fake signals.
In the Forex market, where there are no centralized markets, you can rely on currency futures volume as a proxy for forex volume.

5 - Averages must confirm each other:

The two averages that were emphasized in this rule were the Dowjones industrial average and the Dowjones transportation average. In nowadays as we have more popular averages and largely reflective of the economy, we can apply the same rule for the Dowjones industrial average with the S&P 500, and empirically they give the same desired results. 
As Hamilton stated, one of the shortest ways of going wrong is to accept an indication by one average which has not been clearly confirmed by the other.
Sometimes, while the two averages may vary in strength they will not materially vary in direction, especially in a major movement.
In fact, this rule does very well help traders confirming their views using intermarket analysis, especially where markets now are very interrelated each other.
For example, in forex we can relay on the DXY (U.S Dollar index) to confirm trades on the USD pairs. 

6 – A trend is assumed to be continuous until Definite signals of its Reversal.

Talking about trends and signals, Robert Rhea identified some separate theorems, based on Charles Dow and Hamilton writings.

Trend identification:

Hamilton used peak and trough analysis in order to ascertain the identity of the trend. An uptrend is defined by prices that form a series of rising peaks and troughs, higher highs and higher lows. A downtrend is defined by prices that form a series of declining peaks and troughs, lower highs and lower lows.
Once the trend has been identified, it is assumed valid until proved otherwise. A downtrend is considered valid until a higher low forms and the ensuing advance off of the higher low surpasses the previous reaction high.
Here comes the idea of trend lines. Drawing a line helps emphasize the direction of the trend.
An uptrend is considered in place until a lower low forms and the ensuing decline exceeds the previous low.


Volume should increase in the direction of the primary trend and decrease on corrections.

Trading ranges(lines):

Trading ranges indicate either accumulation or distribution, but it is impossible to tell which until there was a break to the upside or the downside. If there were a break to the upside, then the trading range would be considered an area of accumulation. If there were a break to the downside, then the trading range would be considered an area of distribution.
Hamilton considered the trading range neutral until a breakout occurred. He also warned against attempting to anticipate the breakout.

7 – The theory is not infallible.

Charles Dow, and the Dow Theory theorists, do not guarantee that the theory works 100% successfully every time. That is because of randomness in market movements.
The Dow Theory in not an infallible system for beating the Market. Its successful use as an aid in trading requires serious study, and combination with other analysis tools and elements.

Charles Dow quote:

-          If people with either large or small capital would look upon trading in stocks as an attempt to get 12% per annum on they money instead of 50% weekly, they would come out a good deal better in the long run.”


When analyzing the market, make sure you are objective and see what is there, not what you want to see.
The goal of Dow Theory is to utilize what we do know, not to haphazardly guess about what we don’t know.
Through a set of guidelines, Dow Theory enables traders to identify the primary trend and ride its way.
Finally keep in mind:

      1-      The averages express the sum of all pertinent information.
      2-      The market as a whole has a trend
      3-      The trend is interpreted by reversals
      4-      A signal is made only by confirmation 
      5-      A signal, once given, remains in force until a countersignal is given
      6-      Signals made in third phases have diminishing authority.
      7-      Manipulation and short-selling have no lasting influence on              the trend.
      8-     Conditions that bring about bull markets and bear markets                change slowly.
