De Mark Trend Lines.

When searching for Forex information on the internet you are likely to find articles relating to trendlines and trendline analysis.

Tom DeMark is a specialist in the field of technical market analysis and his best-selling book "The New Science of Technical Analysis" released in 1994 spells out some innovative techniques when it comes to the use of trendlines.

Much Forex information on the internet is of a general nature, and many articles are written about Forex by individuals who are not traders themselves. Tom DeMark on the other hand has had a long career with institutions trading stocks, futures, currencies and options.

His guidelines on the use of trendlines are very specific and they can be helpful to the newer trader who is searching for reliable Forex information on how to use standard indicators.

Here is a brief step-by-step description of how to draw DeMark trendlines:

Note: The term swing high and swing low (also called cycle high and cycle low) refers to the following:

In An Uptrend: A swing high is the wick of a candle that is higher than the wick of the candle to the left and right.

In A Downtrend: A swing low is the wick of a candle that is lower than the wick of the candle to the left and right.

Obviously the more candles to the left and right that are higher in a swing low or lower in a swing high makes the swing or cycle more significant.

An uptrend is where price is making higher highs and higher lows. A downtrend is where price is making lower highs and lower lows.

Drawing DeMark Trendlines

Drawing Trendlines In An Uptrend

1. Examine the bottoms of the candles on your chart and identify the most recent candle wick that is lower than the candle wicks to the immediate right and left of it.


2. Look left on the chart, and identify the previous low candle that has candle wicks higher to the immediate right and left of it which is lower than the current low candle.


3. Now draw a line from the current lowest candle to the previous lowest candle (drawing from right to left).


4. Now take the end of the newly drawn line which stops at the current low candle and extend it forward some distance (drawing from the present position to the right).

Drawing Trendlines In A Downtrend

1. Examine the tops of the candles on your chart and identify the most recent candle wick that is higher than the candle wicks to the immediate right and left of it.


2. Look left on the chart, and identify the previous high candle that has candle wicks lower to the immediate right and left of it which is higher than the current high candle.


3. Now draw a line from the current highest candle to the previous highest candle (drawing from right to left).


4. Now take the end of the newly drawn line which stops at the current high candle and extend it forward some distance (drawing from the present position to the right).

You have now drawn a Tom DeMark trendline.

This can now be a reference point for future price action. It will often be observed that price will come and check this level. If it breaks through, it can mean a change in direction, the significance of which will depend on the time frame being used.

Trendlines drawn on 5 minute or 15 minute charts have much lesser significance than trendlines drawn on higher time frames such as the 1 hour, 4 hour, or daily.

Caution Required

Much Forex information extols the virtues of trendlines as an indicator of possible future price action.

Mr. DeMark certainly has made this a science and his detailed approach to drawing trendlines is certainly more accurate than just drawing general trendlines along the bottoms and tops of trends according to the way the eye sees.

However, trendlines in themselves do not indicate where high probability trades can be taken.

It is important to use a variety of indicators before pulling the trigger. Examining previous levels of support and resistance is probably far more significant in determining where price is likely to hesitate that watching trendlines.

However, they can be useful. If you find a key support or resistance level also coincides with a Fibonacci retracement or extension level which is also at an intersection with a trendline, then you have built a reasonably solid case for a trade.


Using Trendline Analysis As Part Of Your Forex Strategy

Often, not always, price will break a trendline and move away 10 or 20 pips. Then, it comes back to test the backside of that trendline. That’s where you enter the trade.

If the trendline break coincides with your other favorite indicators such as:

• Pivot Points


• Fibonacci Calculations


• Previous Support Or Resistance

then set an entry order for price to take you in when it comes back to test that level.

That way you enter the trade at an optimum level and squeeze even more pips out of the move.

Note the examples below:







USD/CHF
1 Hour Chart

See how price broke the trendline, then came back to test the backside.

If you look carefully at the chart and run your eyes left, you will see that the trendline bounce also coincides with a previous support/resistance level.

If you did some Fibonacci calculations you would also find that same point matches with 50 and 62% retracement levels.

With that convergence of factors, the trendline backside test makes a good entry point!

Stock Trend Lines.

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. It is important that you understand all of the concepts presented in our Support and Resistance article before you continue.



UPTREND LINES

An uptrend line has a positive slope and is formed by connecting two or more low points. The second low must be higher than the first for the line to have a positive slope. Uptrend linesact as support and indicate that net-demand (demand less supply) is increasing even as the price rises. A rising price combined with increasing demand is very bullish, and shows a strong determination on the part of the buyers. As long as prices remain above the trend line, the uptrend is considered solid and intact. A break below the uptrend line indicates that net-demand has weakened and a change in trend could be imminent.



DOWNTREND LINES

A downtrend line has a negative slope and is formed by connecting two or more high points. The second high must be lower than the first for the line to have a negative slope. Downtrendlines act as resistance, and indicate that net-supply (supply less demand) is increasing even as the price declines. A declining price combined with increasing supply is very bearish, and shows the strong resolve of the sellers. As long as prices remain below the downtrend line, the downtrend is solid and intact. A break above the downtrend line indicates that net-supply is decreasing and that a change of trend could be imminent.

For a detailed explanation of trend changes, which are different than just trend line breaks, please see our article on the Dow Theory.

Scale Setting

High points and low points appear to line up better for trend lines when prices are displayed using a semi-log scale. This is especially true when long-term trend lines are being drawn or when there is a large change in price. Most charting programs allow users to set the scale as arithmetic or semi-log. An arithmetic scale displays incremental values (5,10,15,20,25,30) evenly as they move up the y-axis. A $10 movement in price will look the same from $10 to $20 or from $100 to $110. A semi-log scale displays incremental values in percentage terms as they move up the y-axis. A move from $10 to $20 is a 100% gain, and would appear to be a much larger than a move from $100 to $110, which is only a 10% gain.



In the case of EMC, there was a large price change over a long period of time. While there were not any false breaks below the uptrend line on the arithmetic scale, the rate of ascent appears smoother on the semi-log scale. EMC doubled three times in less than two years. On the semi-log scale, the trend line fits all the way up. On the arithmetic scale, three differenttrend lines were required to keep pace with the advance.



In the case of Amazon.com (AMZN), there were two false breaks above the downtrend line as the stock declined during 2000 and 2001. These false break outs could have led to premature buying as the stock continued to decline after each one. The stock lost 60% of its value three times over a two year period. The semi-log scale reflects the percentage loss evenly, and the downtrend line was never broken.

VALIDATION

It takes two or more points to draw a trend line The more points used to draw the trend line, the more validity attached to the support or resistance level represented by the trend line. It can sometimes be difficult to find more than 2 points from which to construct a trend line Even though trend lines are an important aspect of technical analysis, it is not always possible to draw trend lines on every price chart. Sometimes the lows or highs just don't match up, and it is best not to force the issue. The general rule in technical analysis is that it takes two points to draw a trend line and the third point confirms the validity.



The chart of Microsoft (MSFT) shows an uptrend line that has been touched 4 times. After the third touch in Nov-99, the trend line was considered a valid line of support. Now that the stock has bounced off of this level a fourth time, the soundness of the support level is enhanced even more. As long as the stock remains above the trend line (support), the trend will remain in control of the bulls. A break below would signal that net-supply was increasing and that a change in trend could be imminent.

SPACING OF POINTS

The lows used to form an uptrend line and the highs used to form a downtrend line should not be too far apart, or too close together. The most suitable distance apart will depend on the time frame, the degree of price movement, and personal preferences. If the lows (highs) are too close together, the validity of the reaction low (high) may be in question. If the lows are too far apart, the relationship between the two points could be suspect. An ideal trend line is made up of relatively evenly spaced lows (or highs). The trend line in the above MSFT example represents well-spaced low points.



On the Wal-Mart (WMT) example, the second high point appears to be too close to the first high point for a valid trend line; however, it would be feasible to draw a trend line beginning at point 2 and extending down to the February reaction high.

ANGLES

As the steepness of a trend line increases, the validity of the support or resistance level decreases. A steep trend line results from a sharp advance (or decline) over a brief period of time. The angle of a trend line created from such sharp moves is unlikely to offer a meaningful support or resistance level. Even if the trend line is formed with three seemingly valid points, attempting to play a trend line break or to use the support and resistance level established it will often prove difficult.



The trend line for Yahoo! (YHOO) was touched four times over a 5-month period. The spacing between the points appears OK, but the steepness of the trend line is unsustainable, and the price is more likely than not to drop below the trend line. However, trying to time this drop or make a play after the trend line is broken is a difficult task. The amount of data displayed and the size of the chart can also affect the angle of a trend line. Short and wide charts are less likely to have steep trend lines than long and narrow charts. Keep that in mind when assessing the validity and sustainability of a trend line.
