Technical Indicators
Technical indicators are mathematical interpretations of certain aspects of market behavior.
Technical indicators are more objective than area patterns and trend lines, which can be used to determine the balance between the bullish traders and the bearish traders. Each technical indicator can be used by itself, but a combination of two or three is ideal.
Advanced traders might also opt to combine technical indicators with trend line and area pattern formations.
Basic technical indicators fall into three categories, which are: Trend Follower, Oscillator and Volume. Considering that there are preset parameters for each technical indicator, it is best to tweak its settings to maximize its performance. A trader will have to adjust the percentage depending on the currency pair and the time frame he is looking at. In determining what technical indicator best suits you, it is best to get a thorough knowledge on each of these indicators to avoid any form of misinterpretation.
Technical Indicators fall into three categories
Trend Follower
Trend followers, as their names imply, perform best when the markets are trending. In a flat or ranging market, trend-following technical indicators are vulnerable to false signals and whipsaws. Trend following indicators are generally used to identify the direction of the market.
Oscillator
Oscillators were designed to provide signals regarding the overbought and oversold market conditions. Therefore, the signals of oscillators are mostly useful at the extremes of their scales. Crossing the zero line, when applicable, usually generates direction signals.
Volume
Volume indicators are neglected essentials. These are usually used to determine momentum and the health of the trend as well as whether or not the trend is likely to continue or reverse. Volume indicators are most useful to area pattern traders who seek out contractions in volume; because when volume contraction is usually the mark of a consolidation period and if there is a consolidation period, then an area pattern might just form.
Major Technical indicators
Acceleration/Deceleration Technical Indicator (AC) measures acceleration and deceleration of the current driving force. This indicator will change direction before any changes in the driving force, which, it its turn, will change its direction before the price. If you realize that Acceleration/Deceleration is a signal of an earlier warning, it gives you evident advantages.
The nought line is basically the spot where the driving force is at balance with the acceleration. If Acceleration/Deceleration is higher than nought, then it is usually easier for the acceleration to continue the upward movement (and vice versa in cases when it is below nought). Unlike in case with Awesome Oscillator, it is not regarded as a signal when the nought line is crossed. The only thing that needs to be done to control the market and make decisions is to watch for changes in color. To save yourself serious reflections, you must remember: you cannot buy with the help of Acceleration/Deceleration, when the current column is colored red, and you cannot sell, when the current column is colored green.
If you enter the market in the direction of the driving force (the indicator is higher than nought, when buying, or it is lower than nought, when selling), then you need only two green columns to buy (two red columns to sell). If the driving force is directed against the position to be opened (indicator below nought for buying, or higher than nought for selling), a confirmation is needed, hence, an additional column is required. In this case the indicator is to show three red columns over the nought line for a short position and three green columns below the nought line for a long position.
Calculation
AC bar chart is the difference between the value of 5/34 of the driving force bar chart and 5-period simple moving average, taken from that bar chart.
AO = SMA (median price, 5)-SMA(median price, 34)
AC = AO-SMA (AO, 5)
Where:
SMA — Simple Moving Average;
AO — Awesome Oscillator.
In principle, Alligator Technical Indicator is a combination of Balance Lines (Moving Averages) that use fractal geometry and nonlinear dynamics.
The blue line (Alligator’s Jaw) is 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);
The red line (Alligator’s Teeth) is the Balance Line for the value timeframe of one level lower (8-period Smoothed Moving Average, moved by 5 bars into the future);
The green line (Alligator’s Lips) is the Balance Line for the value timeframe, one more level lower (5-period Smoothed Moving Average, moved by 3 bars into the future).
Lips, Teeth and Jaw of the Alligator show the interaction of different time periods. As clear trends can be seen only 15 to 30 per cent 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, the Teeth and the Lips are closed or intertwined, it means the Alligator is going to sleep or is asleep already. As it sleeps, it gets hungrier and hungrier — the longer it will sleep, the hungrier it will wake 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 the interest to the food/price (Balance Lines join together) — this is the time to fix the profit.
Average True Range Technical Indicator (ATR) is an indicator that shows volatility of the market. It was introduced by Welles Wilder in his book “New concepts in technical trading systems”. This indicator has been used as a component of numerous other indicators and trading systems ever since.
Average True Range can often reach a high value at the bottom of the market after a sheer fall in prices occasioned by panic selling. Low values of the indicator are typical for the periods of sideways movement of long duration which happen at the top of the market and during consolidation. Average True Range can be interpreted according to the same principles as other volatility indicators. The principle of forecasting based on this indicator can be worded the following way: the higher the value of the indicator, the higher the probability of a trend change; the lower the indicator’s value, the weaker the trend’s movement is.
Awesome Oscillator Technical Indicator (AO) is a 34-period simple moving average, plotted through the middle points of the bars (H+L)/2, which is subtracted from the 5-period simple moving average, built across the central points of the bars (H+L)/2. It shows us quite clearly what’s happening to the market driving force at the present moment.
Signals to buy
Saucer
This is the only signal to buy that comes when the bar chart is higher than the nought line. One must bear in mind:
the saucer signal is generated when the bar chart reversed its direction from the downward to upward. The second column is lower than the first one and is colored red. The third column is higher than the second and is colored green.
for the saucer signal to be generated the bar chart should have at least three columns.
Keep in mind, that all Awesome Oscillator columns should be over the nought line for the saucer signal to be used.
Nought line crossing
The signal to buy is generated when the bar chart passes from the area of negative values to that of positive. It comes when the bar chart crosses the nought line. As regards this signal:
for this signal to be generated, only two columns are necessary;
the first column is to be below the nought line,
the second one is to cross it (transition from a negative value to a positive one);
simultaneous generation of signals to buy and to sell is impossible.
Two pikes
This is the only signal to buy that can be generated when the bar chart values are below the nought line. As regards this signal, please, bear in mind:
the signal is generated, when you have a pike pointing down (the lowest minimum) which is below the nought line and is followed by another down-pointing pike which is somewhat higher (a negative figure with a lesser absolute value, which is therefore closer to the nought line), than the previous down-looking pike.
the bar chart is to be below the nought line between the two pikes. If the bar chart crosses the nought line in the section between the pikes, the signal to buy doesn’t function. However, a different signal to buy will be generated — nought line crossing.
each new pike of the bar chart is to be higher (a negative number of a lesser absolute value that is closer to the nought line) than the previous pike.
if an additional higher pike is formed (that is closer to the nought line) and the bar chart has not crossed the nought line, an additional signal to buy will be generated.
Signals to sell
Awesome Oscillator signals to sell are identical to the signals to buy. The saucer signal is reversed and is below zero. Nought line crossing is on the decrease — the first column of it is over the nought, the second one is under it. The two pikes signal is higher than the nought line and is reversed too.
Bollinger Bands Technical Indicator (BB) is similar to Envelopes. The only difference is that the bands of Envelopes are plotted a fixed distance (%) away from the moving average, while the Bollinger Bands are plotted a certain number of standard deviations away from it. Standard deviation is a measure of volatility, therefore Bollinger Bands adjust themselves to the market conditions. When the markets become more volatile, the bands widen and they contract during less volatile periods.
Bollinger Bands are usually plotted on the price chart, but they can be also added to the indicator chart (Custom Indicators). Just like in case of the Envelopes, the interpretation of the Bollinger Bands is based on the fact that the prices tend to remain in between the top and the bottom line of the bands. A distinctive feature of the Bollinger Band indicator is its variable width due to the volatility of prices. In periods of considerable price changes (i.e. of high volatility) the bands widen leaving a lot of room to the prices to move in. During standstill periods, or the periods of low volatility the band contracts keeping the prices within their limits.
The following traits are particular to the Bollinger Band:
- abrupt changes in prices tend to happen after the band has contracted due to decrease of volatility.
- if prices break through the upper band, a continuation of the current trend is to be expected.
- if the pikes and hollows outside the band are followed by pikes and hollows inside the band, a reverse of trend may occur.
- the price movement that has started from one of the band’s lines usually reaches the opposite one. The last observation is useful for forecasting price guideposts.
All markets are characterized by the fact that on the most part the prices do not change too much, and only short periods of time (15–30 percent) account for trend changes. Most lucrative periods are usually the case when market prices change according to a certain trend.
A Fractal is one of five indicators of Bill Williams’ trading system, which allows to detect the bottom or the top.
Fractal Technical Indicator, it is a series of at least five successive bars, with the highest HIGH in the middle, and two lower HIGHs on both sides. The reversing set is a series of at least five successive bars, with the lowest LOW in the middle, and two higher LOWs on both sides, which correlates to the sell fractal. The fractals have High and Low values and are indicated with the up and down arrows.
The fractal needs to be filtrated with the use of Alligator. In other words, you should not close a buy transaction, if the fractal is lower than the Alligator’s Teeth, and you should not close a sell transaction, if the fractal is higher than the Alligator’s Teeth. After the fractal signal has been created and is in force, which is determined by its position beyond the Alligator’s Mouth, it remains a signal until it gets attacked, or until a more recent fractal signal emerges.
Gator Oscillator is based on the Alligator and shows the degree of convergence/divergence of the Balance Lines (Smoothed Moving Averages). The top bar chart is the absolute difference between the values of the blue and the red lines. The bottom bar chart is the absolute difference between the values of the red line and the green line, but with the minus sign, as the bar chart is drawn top-down.
Ichimoku Kinko Hyo Technical Indicator is predefined to characterize the market Trend, Support and Resistance Levels, and to generate signals of buying and selling. This indicator works best at weekly and daily charts.
When defining the dimension of parameters, four-time intervals of different length are used. The values of individual lines composing this indicator are based on these intervals:
Tenkan-sen shows the average price value during the first-time interval defined as the sum of maximum and minimum within this time, divided by two;
Kijun-sen shows the average price value during the second time interval;
Senkou Span A shows the middle of the distance between two previous lines shifted forwards by the value of the second time interval;
Senkou Span B shows the average price value during the third time interval shifted forwards by the value of the second time interval.
Chikou Span shows the closing price of the current candle shifted backwards by the value of the second time interval. The distance between the Senkou lines is hatched with another color and called “cloud”. If the price is between these lines, the market should be considered as non-trend, and then the cloud margins form the support and resistance levels.
If the price is above the cloud, its upper line forms the first support level, and the second line forms the second support level;
If the price is below cloud, the lower line forms the first resistance level, and the upper one forms the second level;
If the Chikou Span line traverses the price chart in the bottom-up direction it is signal to buy. If the Chikou Span line traverses the price chart in the top-down direction it is signal to sell.
Kijun-sen is used as an indicator of the market movement. If the price is higher than this indicator, the prices will probably continue to increase. When the price traverses this line the further trend changing is possible. Another kind of using the Kijun-sen is giving signals. Signal to buy is generated when the Tenkan-sen line traverses the Kijun-sen in the bottom-up direction. Top-down direction is the signal to sell. Tenkan-sen is used as an indicator of the market trend. If this line increases or decreases, the trend exists. When it goes horizontally, it means that the market has come into the channel.
The Momentum Technical Indicator measures the amount that a security’s price has changed over a given time span.
There are basically two ways to use the Momentum indicator:
You can use the Momentum indicator as a trend-following oscillator similar to the Moving Average Convergence/Divergence (MACD). Buy when the indicator bottoms and turns up and sell when the indicator peaks and turns down. You may want to plot a short-term moving average of the indicator to determine when it is bottoming or peaking.
If the Momentum indicator reaches extremely high or low values (relative to its historical values), you should assume a continuation of the current trend. For example, if the Momentum indicator reaches extremely high values and then turns down, you should assume prices will probably go still higher. In either case, only trade after prices confirm the signal generated by the indicator (for example, if prices peak and turn down, wait for prices to begin to fall before selling).
You can also use the Momentum indicator as a leading indicator. This method assumes that market tops are typically identified by a rapid price increase (when everyone expects prices to go higher) and that market bottoms typically end with rapid price declines (when everyone wants to get out). This is often the case, but it is also a broad generalization.
As a market peaks, the Momentum indicator will climb sharply and then fall off — diverging from the continued upward or sideways movement of the price. Similarly, at a market bottom, Momentum will drop sharply and then begin to climb well ahead of prices. Both of these situations result in divergences between the indicator and prices.
The Moving Average Technical Indicator shows the mean instrument price value for a certain period of time. When one calculates the moving average, one averages out the instrument price for this time period. As the price changes, its moving average either increases, or decreases.
There are four different types of moving averages: Simple (also referred to as Arithmetic), Exponential, Smoothed and Linear Weighted. Moving averages may be calculated for any sequential data set, including opening and closing prices, highest and lowest prices, trading volume or any other indicators. It is often the case when double moving averages are used.
The only thing where moving averages of different types diverge considerably from each other, is when weight coefficients, which are assigned to the latest data, are different. In case we are talking of simple moving average, all prices of the time period in question, are equal in value. Exponential and Linear Weighted Moving Averages attach more value to the latest prices.
The most common way to interpreting the price moving average is to compare its dynamics to the price action. When the instrument price rises above its moving average, a buy signal appears, if the price falls below its moving average, what we have is a sell signal.
This trading system, which is based on the moving average, is not designed to provide entrance into the market right in its lowest point, and its exit right on the peak. It allows to act according to the following trend: to buy soon after the prices reach the bottom, and to sell soon after the prices have reached their peak.
Moving averages may also be applied to indicators. That is where the interpretation of indicator moving averages is similar to the interpretation of price moving averages: if the indicator rises above its moving average, that means that the ascending indicator movement is likely to continue: if the indicator falls below its moving average, this means that it is likely to continue going downward.
Here are the types of moving averages on the chart:
Simple Moving Average (SMA)
Exponential Moving Average (EMA)
Smoothed Moving Average (SMMA)
Linear Weighted Moving Average (LWMA)
Moving Average Convergence/Divergence is the next trend-following dynamic indicator. It indicates the correlation between two price moving averages.
The Moving Average Convergence/Divergence Technical Indicator is the difference between a 26-period and 12-period Exponential Moving Average (EMA). In order to clearly show buy/sell opportunities, a so-called signal line (9-period indicators` moving average) is plotted on the MACD chart.
The MACD proves most effective in wide-swinging trading markets. There are three popular ways to use the Moving Average Convergence/Divergence: crossovers, overbought/oversold conditions, and divergences.
Crossovers
The basic MACD trading rule is to sell when the MACD falls below its signal line. Similarly, a buy signal occurs when the Moving Average Convergence/Divergence rises above its signal line. It is also popular to buy/sell when the MACD goes above/below zero.
Overbought/oversold conditions
The MACD is also useful as an overbought/oversold indicator. When the shorter moving average pulls away dramatically from the longer moving average (i.e., the MACD rises), it is likely that the security price is overextending and will soon return to more realistic levels.
Divergence
An indication that an end to the current trend may be near occurs when the MACD diverges from the security. A bullish divergence occurs when the Moving Average Convergence/Divergence indicator is making new highs while prices fail to reach new highs. A bearish divergence occurs when the MACD is making new lows while prices fail to reach new lows. Both of these divergences are most significant when they occur at relatively overbought/oversold levels.
Parabolic SAR Technical Indicator was developed for analyzing the trending markets. The indicator is constructed on the price chart. This indicator is similar to the Moving Average Technical Indicator with the only difference that Parabolic SAR moves with higher acceleration and may change its position in terms of the price. The indicator is below the prices on the bull market (Up Trend), when it’s bearish (Down Trend), it is above the prices.
If the price crosses Parabolic SAR lines, the indicator turns, and its further values are situated on the other side of the price. When such an indicator turn does take place, the maximum or the minimum price for the previous period would serve as the starting point. When the indicator makes a turn, it gives a signal of the trend end (correction stage or flat), or of its turn.
The Parabolic SAR is an outstanding indicator for providing exit points. Long positions should be closed when the price sinks below the SAR line, short positions should be closed when the price rises above the SAR line. It is often the case that the indicator serves as a trailing stop line.
If the long position is open (i.e., the price is above the SAR line), the Parabolic SAR line will go up, regardless of what direction the prices take. The length of the SAR line movement depends on the scale of the price movement.
The Relative Strength Index Technical Indicator (RSI) is a price-following oscillator that ranges between 0 and 100. When Wilder introduced the Relative Strength Index, he recommended using a 14-day RSI. Since then, the 9-day and 25-day Relative Strength Index indicators have also gained popularity.
A popular method of analyzing the RSI is to look for a divergence in which the security is making a new high, but the RSI is failing to surpass its previous high. This divergence is an indication of an impending reversal. When the Relative Strength Index then turns down and falls below its most recent trough, it is said to have completed a “failure swing”. The failure swing is considered a confirmation of the impending reversal.
Ways to use Relative Strength Index for chart analysis:
Tops and bottoms
The Relative Strength Index usually tops above 70 and bottoms below 30. It usually forms these tops and bottoms before the underlying price chart;
Chart Formations
The RSI often forms chart patterns such as head and shoulders or triangles that may or may not be visible on the price chart;
Failure swing (Support or Resistance penetrations or breakouts)
This is where the Relative Strength Index surpasses a previous high (peak) or falls below a recent low (trough);
Support and Resistance levels
The Relative Strength Index shows, sometimes more clearly than price themselves, levels of support and resistance.
Divergences
As discussed above, divergences occur when the price makes a new high (or low) that is not confirmed by a new high (or low) in the Relative Strength Index. Prices usually correct and move in the direction of the RSI.
The main point of Relative Vigor Index Technical Indicator (RVI) is that on the bull market the closing price is, as a rule, higher, than the opening price. It is the other way around on the bear market. So, the idea behind Relative Vigor Index is that the vigor, or energy, of the move is thus established by where the prices end up at the close. To normalize the index to the daily trading range, divide the change of price by the maximum range of prices for the day. To make a smoother calculation, one uses Simple Moving Average. 10 is the best period. To avoid probable ambiguity, one needs to construct a signal line, which is a 4-period symmetrically weighted moving average of Relative Vigor Index values. The concurrence of lines serves as a signal to buy or to sell.
The Stochastic Oscillator Technical Indicator compares where a security’s price closed relative to its price range over a given time period. The Stochastic Oscillator is displayed as two lines. The main line is called %K. The second line, called %D, is a Moving Average of %K. The %K line is usually displayed as a solid line and the %D line is usually displayed as a dotted line.
There are several ways to interpret a Stochastic Oscillator. Three popular methods include:
Buy when the Oscillator (either %K or %D) falls below a specific level (for example, 20) and then rises above that level. Sell when the Oscillator rises above a specific level (for example, 80) and then falls below that level;
Buy when the %K line rises above the %D line and sell when the %K line falls below the %D line;
Look for divergences. For instance: where prices are making a series of new highs and the Stochastic Oscillator is failing to surpass its previous highs.
Williams’ Percent Range Technical Indicator (%R) is a dynamic technical indicator, which determines whether the market is overbought/oversold. Williams’ %R is very similar to the Stochastic Oscillator. The only difference is that %R has an upside-down scale and the Stochastic Oscillator has internal smoothing.
To show the indicator in this upside-down fashion, one places a minus symbol before the Williams Percent Range values (for example -30%). One should ignore the minus symbol when conducting the analysis.
Indicator values ranging between 80 and 100% indicate that the market is oversold. Indicator values ranging between 0 and 20% indicate that the market is overbought.
As with all overbought/oversold indicators, it is best to wait for the security’s price to change direction before placing your trades. For example, if an overbought/oversold indicator is showing an overbought condition, it is wise to wait for the security’s price to turn down before selling the security.
An interesting phenomenon of the Williams Percent Range indicator is its uncanny ability to anticipate a reversal in the underlying security’s price. The indicator almost always forms a peak and turns down a few days before the security’s price peaks and turns down. Likewise, Williams Percent Range usually creates a trough and turns up a few days before the security’s price turns up.
