Alligator

A unique use of fractal geometry and nonlinear dynamics is used to create the method of calculations for the Alligator Indicator. Used in combination with the Gator Indicator, the Alligator has proved to be effective at pinpointing large market trends.

 

Example of the Alligator

 

Components

Alligator’s Jaw (blue line): The Balance Line for the timeframe that was used to build the chart (13 period Smoothed Moving Average, moved into the future by 8 bars).

 

Alligator’s Teeth (red line): The Balance Line for the value timeframe of one level lower (8 period Smoothed Moving Average, moved by 5 bars into the future).

 

Alligator’s Lips (green line): The Balance Line for the value timeframe, one more level lower (5 period Smoothed Moving Average, moved by 3 bars into the future).

 

The Lips, Teeth, and Jaw of the Alligator show the interaction of different time periods. As clear trends can be seen only 15 to 30 percent of the time, it is essential to follow them and refrain from working on markets that fluctuate only within certain price periods.

 

When the Jaw, Teeth and Lips are closed or intertwined, the Alligator is going to sleep or is asleep already. As it sleeps, it gets hungrier and hungrier: the longer it sleeps, the hungrier it will be when it wakes up. The first thing it does after it wakes up is to open its mouth and yawn. Then the smell of food comes to its nostrils: flesh of a bull or flesh of a bear, and the Alligator starts to hunt it. Having eaten enough to feel quite full, the Alligator starts to lose interest in the food/price (Balance Lines join together), and this is the time to fix the profit.

Bollinger Bands

Bollinger Bands are a type of trading envelope. They are lines at an interval around the moving average. They consist of a moving average and two different standard deviations represented as a line above the MA (Moving Average) and a line below the MA. The line above is the MA plus two standard deviations; the line below is the MA minus two standard deviations. Bollinger Bands are used to determine overbought and oversold conditions and to project price targets.

 

John Bollinger created Bollinger Bands in an effort to gauge the volatility and condition of a market. These bands are used to determine the trading range and give an indication of when to buy and when to sell. Bollinger Bands are also used to indicate market volatility, the wider the bands the greater the volatility. Inversely, the narrower the bands, the lesser the volatility. By plotting two lines at an interval around a moving average, Bollinger bands give a good indication of market conditions and price relation. The moving average which the band is based on works as an indicator to confirm trade signals.

 

Calculation

Calculate the moving average with this formula:

 

 

Subtract the moving average from each of the individual data points used in the moving average calculation. This gives you a list of deviations from the average. Square each deviation and add them all together. Divide this sum by the number of periods you selected.

 

 

Take the square root of d. This gives you the standard deviation.

 

 

Compute the bands by using the following formulas:

 

 

Pn: The price you pay for the nth interval.

n: The number of periods you select.

 

Buy/Sell Signals

A buy signal occurs when a chart bottom is below the lower band followed by a bottom above the lower band. A sell signal occurs when a chart top is above the uppermost band followed by another top that is below the upper band.

Period: The number of bars used to calculate the study. John Bollinger, the creator of this study, states that those periods of less than ten days do not seem to work well for Bollinger Bands. He says the optimal period for most applications is 20 or 21. Default is 20. To add a displacement, add a second number in the period box (with only a space between the two numbers.)

 

Type: Select Simple, Linear Weight, or Exponential.

 

Data: Select Open, High, Low, or Close.

 

% Deviation: The percent of one standard deviation. John Bollinger suggests that if you reduce the number of days used to calculate the bands, you should also reduce the number of deviations and vise versa. For example, 200 percent of a standard deviation means two deviations above and two deviations below the moving average. If you use a period of 50, you may want to use 250 percent of a standard deviation. For a period of 10, you may want to use 150 or 100 percent.

Donchian Channels (DON)

Donchian Channels were created by Richard Donchian, an expert in trends. The DON is a simple trend breakout system. The channel works well in trending markets, but not as well in sideways moving markets.

 

Donchian Channels measure volatility by placing bands at a specified period deviation. These bands are charted two standard deviations from the market price. As the market price changes, the value of two standard deviations also changes. This value is what comprises the Donchian Channel’s band width, representing the expanding and contracting of the bands based on recent price volatility.

 

Calculation

The calculation of the DON is here:

 

Donchian Channel High = MAX (HI, n)

Donchian Channel Low = MAX (LO, n)

Keltner Bands

Kelter Bands were developed by Chester Keltner and Modified by Linda Raschke. They are traditional moving average envelopes based on Exponential Moving Averages. The probability is that prices will remain within the channel, as with all band-type indicators. A break above the channel is an anticipation of higher prices. When prices close below the lower band, we anticipate lower prices.

 

The middle line (20 period EMA) in a rising market should provide support. In a falling market, the middle line should provide resistance. Keltner Bands, as with any moving average indicator, seem to work great in strongly tending markets, but not so well in sideways markets. Just like all trend-following systems, the Keltner Bands are not meant to spot tops or bottoms. Use the Keltner Bands in conjunction with other indicators such as RSI or MACD. Using it in combination with either of these will help provide verification of the strength of a market.

 

Example of Keltner Bands

 

Calculation

The calculation for the top, or Plus Band, is here:

 

2 (ATR over 10 periods) + (20 period exponential moving average)

 

The calculation for the bottom, or Minus Band, is here:

 

2 (ATR over 10 periods) - (20 period exponential moving average)

Moving Average Lines

The moving average, or simple moving average, represents the average of the last several closing prices. The moving average is simple to compute, easy to understand, and reliable under tests. This simplicity is the strength of the moving average.

 

The basic moving average is computed the same as any other mathematical average. The most common way of determining the moving average of a market is to take the closing price over a certain number of days, add them together, and divide by the select number of days.

 

Moving averages are generally thought to be indicators of trend. For example, conventional interpretation is that once prices cross from below the moving average to above it, the trend is considered up. On the other hand, if prices go from above the moving average to below it, the trend of the market is considered down.

 

The purpose of the simple moving average is to track the progress of the trend. Moving averages can potentially keep you in the trend for a long time. The moving average gives you an indication of the trend being up (prices above the moving average) or down (below the moving average). However, the moving average gives you no indication of the length or duration of the trend.

 

Double Moving Average

Double moving averages use two different averages in tandem. The first average is generally a faster reacting average using a shorter period of time, usually 10 days. The second average is a slower reacting average that will indicate longer-term price movement.

 

Using these two averages together helps to alleviate whipsaws by giving a basis of comparison. The faster average breaking above the slower average is a buy signal, the faster average breaking below the slower average is a sell signal.

When using two different moving averages the trader gets a clearer picture of price indications. By combining a slower moving 20-day average, with a quicker reacting 10-day average, you can see where the long-term indications are going.

 

You would sell once the faster moving average crosses below the slower trend because that’s an indication of change in trend. Near-term prices should be rising at a greater rate than longer-term prices in a good upward trending market, and vice versa for a down trend.

 

Triple Moving Average

The system of triple moving averages is employed by plotting three different moving averages together. The first of these averages is a faster average that only looks at the short-term price direction. The second average is a medium average that reacts to a longer period of time, but not as long as the final average. The third average is the slowest to react, because it takes an average of the longest period of time.

 

A 10, 20, and 40 day moving average system would be considered a triple moving average. The first average, the 10-day, is the quickest to move when prices show a change. The second average, the 20-day, is the medium average that does not show change until the prices have moved for a longer period of time. Finally the slowest moving of the averages is the 40-day. This slow average will not indicate a difference until prices have made a significant move. Shorter-term moving averages, being more sensitive to changes in price, are said to follow the trend more closely. The middle or medium average would follow less closely and the slowest or least sensitive average would lag the most.

 

The use of the triple moving average is to buy when all three averages move to be in an upward trend or to sell when these averages are in a downtrend. The upward trend appears when the fastest average is higher than both of the other averages, the medium is above the slowest, and the longer term moving average is on the bottom.

 

This look would be reversed for a strong down trend with slow average on top, followed by the medium average, and the fastest on bottom.

 

Calculation

The calculation for the moving average is here:

 

Mat = (P1 +... + Pn) / n

 

Mat: The moving average for the current period.

Pn: The price for the nth interval.

n: The length of the moving average.

 

Compute the average of the past n intervals using the price specified for that period. Now use real values to compute a five interval moving average. If you assume the following prices, the calculations are here:

 

MA = (7380 + 7375 + 7385 + 7390 + 7395) / 5

      = 36925 / 5

      = 7385

 

The calculation for the Linearly Weighted is here:

 

Mat = [(P1 x (n –1)] + …+ [Pn x (n – n)]

Denom = n + n-1 + n-2 +…+ 1

 

MA = Mat / Denom

 

n: The length of the moving average.

Pn: The price for the nth interval.

MA: The moving average for the current period.

 

The calculation for the Exponential is here:

 

fPerc = 2 / (n + 1)

MAt = (P x fPerc) + [MA(t-1) x (1 – fPerc)]

 

MA: The moving average for the current period.

t: The current time period.

Parabolic Stop and Reversal (PSAR)

The Parabolic SAR, developed by Welles Wilder, creator of RSI and DMI, sets trailing price stops for either long or short positions. Also referred to as the stop-and-reversal indicator, Parabolic SAR is more popular for setting stops than for establishing direction or trend. Wilder recommended establishing the trend first, and then trading with Parabolic SAR in the direction of the trend. If the trend is up, but the underlying price drops back below the trailing PSAR indicator, then sell or liquidate your long position. If the trend is down, and the underlying price rises above the trailing PSAR indicator then buy or liquidate your short position.

 

Calculation

Once the market establishes a direction, the initial SAR becomes the extreme price for the two intervals. The extreme price is either the lowest price or highest price for the two trading intervals. The short position uses the high, and the long position uses the low.

 

The calculation for the PSAR is here:

 

SARt = SARt-1 + [ a x ( EPtrade - SARt-1) ]

 

SARt: The stop and reverse price for the current interval.

SARt-1: The stop and reverse price for the previous interval.

a: The acceleration factor.

EPtrade: The extreme price for the trade.

 

The SAR is always the "stop and reverse" price point. This is the point you would want to liquidate your current position and establish the opposite position.

 

The acceleration factor, a, is a weighting factor. In Wilder’s work, the initial value for the acceleration factor is .02. The acceleration factor increases by a value of .02 each time the extreme price changes for the trade. You do not increment the acceleration factor if the extreme price fails to change. The value for a, the acceleration factor, never exceeds .20 in Wilder’s methodology.

 

The extreme price (EP) for the trade is the highest or lowest price achieved during the trade. If you have a long position, use the new highs as the extreme price. When you have a short position, use the new lows as the extreme price. The extreme price concept allows for normal market corrections without immediately triggering the SAR price. It keeps the SAR price moving in the direction of the market.

Pivot Points

Pivot points used to be referred to as "traders numbers" because of the popularity of these points amongst floor traders. The theory behind them is that markets tend to have overlap from one period to another. On most days, the daily high or low is within the previous day’s range, as with the previous week’s extremes, and previous month’s extremes. In this sense, pivot points are a counter trend indicator.

 

However, many traders believe that once one point is violated, the next point will be tested, making a violation of these support and resistance levels a clue in trend following. Though we cannot vouch for the truth of this statement, the popularity of pivot points amongst floor traders tends to make these points worth watching.

 

The popularity of these numbers can be seen on any day when the exchanges are cleaned-up. The trading floor is literally piled high with folded pieces of paper that contain pivot points calculated on them.

 

The uses of pivot points varies greatly by trader. The most common function of the daily pivot is as a guide. If prices are trading above the pivot point, then the trend is considered up. Traders may wish to take short-term positions on a violation of the daily pivot to the upside with an initial upside objective of the 1st resistance level. If prices stall or slow at the first resistance level, then aggressive traders may wish to take profits. However, if the first Resistance level is violated to the upside, then the market should go on to test the second resistance level. If prices have violated the first resistance level, then this level should act as support on future pullbacks, as should the pivot point.

 

The opposite is true for support levels. A violation of the daily pivot to the downside indicates that the daily trend is down, with a downside target being the first support level. If the market stalls, then traders may wish to take profits on short positions, or initiate long positions in anticipation of a retracement to the daily pivot. However, if the first support level is violated, the day is said to be a strongly down trending day, and as such should move down further to test the second support level. As with the resistance numbers, the support numbers, once violated, become resistance lines to trade with in the trend.

 

Though originally used as a means for floor trading, longer-term traders can use pivot points for longer periods. Try plotting the weekly pivot points on the daily chart and using it for shorter term positioning on the daily charts. Pivot points can also be calculated using the monthly pivot points on the daily chart, and used for longer-term positions.

 

Example of Pivot Points

 

Calculation

There are several methods used to determine the Pivot Point. We have included the three different formulas in Track ‘n Trade 5.0.

 

Traditional formulas:

Pivot Point = (H + L + C)/3

First Support Line = (2 x Pivot Point) - H

First Resistance Line = (2 x Pivot Point) - L

Second Support Line = Pivot Point - (H - L)

Second Resistance Line = Pivot + (H - L)

 

Variation 1:

This method changes the formula used to derive the Pivot Point. The changes include adding the trading day’s open and calculating the average of the four values. With this variation, one takes into account both opening gaps and overnight trading. The calculation is here:

 

Pivot Point = (H* + L* + C* + O**) / 4

 

*=Yesterday

**=Today

 

Variation 2:

This method changes the formula used to derive the Pivot Point as well. In this method you substitute yesterday’s close with today’s open. Variation 2 also takes into account opening gaps and overnight trading. The calculation is here:

 

Pivot Point = (H* + L* + O**) / 3

 

*=Yesterday

**=Today

10x8 Moving Average Calculation

Just as it is easier to ride a bike downhill than uphill, it seems prices fall faster than they rise. Due to this perceived quirk in pricing, the legendary market analyst, author, and seminar speaker, Jake Bernstein, developed the 10x8 moving average system.

 

This system uses two simple moving averages, but they are calculated in a slightly different manner than those traditionally used. The first moving average is a moving average of the daily highs, as opposed to that of the daily settlement. The second moving average is calculated using the daily lows.

 

Though Mr. Bernstein recommends using a 10 period moving average of the daily highs and an 8 period moving average of the daily lows based on his observation that prices tend to fall about 20% faster than they rise, any combination would do the trick. Generally, accepting market lore that prices fall faster than they rise, the moving average of the lows should be of shorter term duration than that of the highs.

 

The most basic use of the 10x8 Moving Average is to look for a breakout above the upper moving average to initiate a buy signal. When the daily settlement price exceeds the average high of the last 10 days, this indicator flashes a buy signal indicating that the trend of the market should be up.

Zig Zag

The Zig Zag Indicator acknowledges minimum price changes and ignores those that do not fit the criteria.

 

Calculation

A Zig Zag set at 10% with OHLC bars would yield a line that only reverses after a change from high to low of 10% or greater. All movements less than 10% would be ignored. If a commodity traded from a low of 100 to a high of 109, the Zig Zag would not draw a line because the move was less than 10%. If the stock advanced from a low of 100 to a high of 110, then the Zig Zag would draw a line from 100 to 110. If the commodity continued on to a high of 112, this line would be extended to 112 (100 to 112). The Zig Zag would not reverse until the commodity declined 10% or more from its high. From a high of 112, a commodity would have to decline 11.2 points (or to a low of 100.8) for the Zig Zag to reverse and display another line.
