To Have A Valid Dow Signal Both The Dow Transport Index And The Dow Industrial Index Must Confirm:
This is perhaps the most important of the Dow Theory rules. History has shown that there can be many false movements of either index but confirmation by both greatly improves the reliability and use of the theory.
The Candlestick format shows the full range of price movement i.e. high, low, open and close in a more graphic manner than on the Bar chart . Thus we more easily get a sense of market sentiment behind price changes.
Support is the price level at which demand is thought to be strong enough to prevent the price from declining further. The logic dictates that as the price declines towards support and gets cheaper, buyers become more inclined to buy and sellers become less inclined to sell. By the time the price reaches the support level, it is believed that demand will overcome supply and prevent the price from falling below support.
Resistance is the price level at which selling is thought to be strong enough to prevent the price from rising further. The logic dictates that as the price advances towards resistance, sellers become more inclined to sell and buyers become less inclined to buy. By the time the price reaches the resistance level, it is believed that supply will overcome demand and prevent the price from rising above resistance.
Technical analysis is built on the assumption that prices trend. Trend Lines are an important tool in technical analysis for both trend identification and confirmation. A trend line is a straight line that connects two or more price points and then extends into the future to act as a line of support or resistance. Many of the principles applicable to support and resistance levels can be applied to trend lines as well.
A price channel is a continuation pattern that slopes up or down and is bound by an upper and lower trend line. The upper trend line marks resistance and the lower trend line marks support. Price channels with negative slopes (down) are considered bearish and those with positive slopes (up) bullish.
Main Trend Line: It takes at least two points to draw the main trend line. This line sets the tone for the trend and the slope. For a bullish price channel, the main trend line extends up and at least two reaction lows are required to draw it. For a bearish price channel, the main trend line extends down and at least two reaction highs are required to draw it.
Channel Line: The line drawn parallel to the main trend line is called the channel line. Ideally, the channel line will be based off of two reaction highs or lows. However, after the main trend line has been established, some analysts draw the parallel channel line using only one reaction high or low. The channel line marks support in a bearish price channel and resistance in a bullish price channel.
The falling wedge is a bullish pattern that begins wide at the top and contracts as prices move lower. This price action forms a cone that slopes down as the reaction highs and reaction lows converge. In contrast to symmetrical triangles, which have no definitive slope and no bias, falling wedges definitely slope down and have a bullish bias. However, this bullish bias cannot be realized until a resistance breakout.
The rising wedge is a bearish pattern that begins wide at the bottom and contracts as prices move higher and the trading range narrows. In contrast to symmetrical triangles, which have no definitive slope and no bullish or bearish bias, rising wedges definitely slope up and have a bearish bias.
Flags and Pennants are short-term continuation patterns that mark a small consolidation before the previous move resumes. These patterns are usually preceded by a sharp advance or decline with heavy volume, and mark a mid-point of the move.
The Double Top Reversal is a bearish reversal pattern typically found on bar charts, line charts and candlestick charts. As its name implies, the pattern is made up of two consecutive peaks that are roughly equal, with a moderate trough in-between.
A Head and Shoulders reversal pattern forms after an uptrend, and its completion marks a trend reversal. The pattern contains three successive peaks with the middle peak (head) being the highest and the two outside peaks (shoulders) being low and roughly equal. The reaction lows of each peak can be connected to form support, or a neck line .Once the neckline is broken price normally collapses radically.
As a major reversal pattern, the Head and Shoulders Bottom forms after a downtrend, and its completion marks a change in trend. Again its structure is the inverse of the Head & Shoulder Top and price normally rises rapidly once the neck line is breached.
The ascending triangle is a bullish formation that usually forms during an uptrend as a continuation pattern. There are instances when ascending triangles form as reversal patterns at the end of a downtrend, but they are typically continuation patterns. Regardless of where they form, ascending triangles are bullish patterns that indicate accumulation.
Moving averages smooth the price data to form a trend following indicator. They do not predict price direction, but rather define the current direction with a lag. Moving averages lag because they are based on past prices. Despite this lag, moving averages help smooth price action and filter out the noise. They also form the building blocks for many other technical indicators and overlays, such as Bollinger Bands and MACD. The two most popular types of moving averages are the Simple Moving Average (SMA) and the Exponential Moving Average (EMA) . These moving averages can be used to identify the direction of the trend or define potential support and resistance levels.
The Advance Decline Line (AD Line) is a breadth indicator based on Net Advances, which is the number of advancing stocks less the number of declining stocks. Net Advances is positive when advances exceed declines and negative when declines exceed advances. The AD Line is a cumulative measure of Net Advances. It rises when Net Advances is positive and falls when Net Advances is negative.
Developed by Gerald Appel in the late seventies, Moving Average Convergence-Divergence (MACD) is one of the simplest and most effective momentum indicators available. MACD turns two trend-following indicators, moving averages, into a momentum oscillator by subtracting the longer moving average from the shorter moving average. As a result, MACD offers the best of both worlds: trend following and momentum. MACD fluctuates above and below the zero line as the moving averages converge, cross and diverge. Traders can look for signal line crossovers, centerline crossovers and divergences to generate signals. Because MACD is unbounded, it is not particularly useful for identifying overbought and oversold levels.
Divergences form when MACD trend diverges from the price action of the underlying security. A bullish divergence forms when a security records a lower low and MACD forms a higher low. A bearish divergence is the inverse.
Developed by George C. Lane in the late 1950s, the Stochastic Oscillator is a momentum indicator that shows the location of the close relative to the high-low range over a set number of periods. According to an interview with Lane, the Stochastic Oscillator "doesn't follow price, it doesn't follow volume or anything like that. It follows the speed or the momentum of price. As a rule, the momentum changes direction before price." As such, bullish and bearish divergences in the Stochastic Oscillator can be used to foreshadow reversals. This was the first, and most important, signal that Lane identified. Lane also used this oscillator to identify bull and bear set-ups to anticipate a future reversal. Because the Stochastic Oscillator is range bound, is also useful for identifying overbought and oversold levels.
Divergences form when a new high or low in price is not confirmed by the Stochastic Oscillator. A bullish divergence forms when price records a lower low, but the Stochastic Oscillator forms a higher low. This shows less downside momentum that could foreshadow a bullish reversal. A bearish divergence forms when price records a higher high, but the Stochastic Oscillator forms a lower high. This shows less upside momentum that could foreshadow a bearish reversal.
Developed by John Bollinger, Bollinger Bands are volatility bands placed above and below a moving average. Volatility is based on the standard deviation, which changes as volatility increase and decreases. The bands automatically widen when volatility increases and narrow when volatility decreases. This dynamic nature of Bollinger Bands also means they can be used on different securities with the standard settings. For signals, Bollinger Bands can be used to identify M-Tops and W-Bottoms or to determine the strength of the trend.
Setting: Normally use the 20 DMA as the centre line.
Bollinger Bands consist of a middle band with two outer bands. The middle band is a simple moving average that is usually set at 20 periods. A simple moving average is used because a simple moving average is also used in the standard deviation formula. The look-back period for the standard deviation is the same as for the simple moving average. The outer bands are usually set 2 standard deviations above and below the middle band.
The Average Directional Index (ADX), Minus Directional Indicator (-DI) and Plus Directional Indicator (+DI) represent a group of directional movement indicators that form a trading system developed by Welles Wilder. Wilder designed ADX with commodities and daily prices in mind, but these indicators can also be applied to stocks. The Average Directional Index (ADX) measures trend strength without regard to trend direction. The other two indicators, Plus Directional Indicator (+DI) and Minus Directional Indicator (-DI), complement ADX by defining trend direction. Used together, chartists can determine both the direction and strength of the trend.
At its most basic the Average Directional Index (ADX) can be used to determine if a security is trending or not. This determination helps traders choose between a trend following system or a non-trend following system. Wilder suggests that a strong trend is present when ADX is above 25 and no trend is present when below 20. There appears to be a gray zone between 20 and 25. As noted above, chartists may need to adjust the settings to increase sensitivity and signals. ADX also has a fair amount of lag because of all the smoothing techniques. Many technical analysts use 20 as the key level for ADX.
