Drawing trendlines on stock charts is a powerful way to assess the market’s direction. They help you understand the trend direction and timeframe to set expectations for future market moves, helping you improve your trading.
Do you know if the market is in an uptrend, downtrend, or consolidation?
Trendlines are a visual representation of the trend direction in the stock market. They are formed by connecting two or more significant highs or lows on a stock chart, creating a diagonal line that indicates the general price movement of the asset.
Trendlines matter because buying stocks in an uptrend can be profitable, but in a downtrend, it may not. Learn the simple and effective ways to determine if the market is heading up or down.
Why Draw Trendlines on Stock Charts?
Drawing trendlines on stock charts is one of the most fundamental technical analysis skills that every trader should know. Trendlines help identify support and resistance levels as well as possible entry points. Trendlines enable you to visualize the direction of the stock. Additionally, stock prices breaking through trendlines can provide valuable buy or sell signals.
What is a Stock Price Trend?
A stock price trend is the direction of a stock’s movement over time. Upward trends indicate that the stock price is increasing, and downward trends, or downtrends, indicate that the stock price is decreasing. It’s important to identify whether a stock is trending.
There are three types of trends: uptrend, downtrend, and consolidation. Multiple timeframes must also be considered.
A Simple Rule for Drawing TrendLines
To draw effective trendlines, you need to connect the highest price highs, which is the resistance line. Then, you connect the stock price’s lowest lows, which is the support line.
When the price breaks up through the resistance line, it is a new high and a potential buy signal. This could be a sell signal when the price breaks down through the support line.
3 Types of Stock Price Trends
- Uptrend – This is a series of increasing highs and lows over time. A stock in an uptrend can show periods of consolidation, but the overall trend should be up.
- Downtrend – This series of decreasing highs and lows indicates that the stock price is moving downwards. A downtrend can also have periods of consolidation, but the overall trend should be down.
- Sideways Trend – This is when a stock price tends to move in a sideways pattern for an extended period. There is usually no clear direction with sideways trends, and they can last for several weeks or even months.
It’s important to note that these trends are not always clear-cut. There can be periods when a stock is moving in an uptrend but shows signs of a potential sell signal or a downtrend that may show signs of a potential buy signal. This is why it is important to follow technical analysis and monitor support and resistance points.
Time frames must also be considered when evaluating a trend; for this, we will refer to Charles Dow’s classification in Dow Theory.
3 Stock Trend Timeframes
- Long-term Trend – This is the longest trend and can last for months or years.
- Medium-term Trend – This trend typically lasts from weeks to months and can be in the direction of the long-term trend or move in the opposite direction.
- Short-term Trend – A minor trend usually lasts from a few days to weeks and is typically the trend that day traders follow.
By understanding these different time frames, traders can identify potential entry and exit points to better capitalize on a stock’s price movements. Awareness of these three trends will also help determine when an investor should stay out of the market to avoid larger losses in their portfolio.
You could be specific about the market trend by combining the above terms. For example, you could say the market is in a short-term up-trend but a long-term down-trend. But isn’t that contradictory, the market being both an uptrend and a downtrend simultaneously?
Not really; it makes perfect sense.

How to Draw Uptrends
When a market is in an uptrend, prices should make higher highs and lows. Although prices may pull back during the uptrend, they should not break through the previous low. To draw an uptrend line, you start by identifying two consecutive peaks. Then, you connect those peaks with a straight line. The same process confirms the uptrend line when another peak is created.
Example: Drawing Uptrend Trendlines
- To evaluate an upward trend, draw a line joining the highest highs
- For the floor of the uptrend, draw a line connecting the lowest lows. The price here bounces three times off the bottom line but then proceeds higher.
- A trendline is drawn to show that the price has moved strongly past the previous high. This is a BUY Signal at $35.50.
- Finally, the price is exhausted and falls through the bottom resistance line at $51. This break of the upward support line is a sell signal.
Quick Tip: The more bounces off a trendline the stronger the trend.
Buying and selling based on the trendlines shown here would have bagged you a 49% win. Alas, life is never that easy, and showing this in retrospect does mean we have the benefit of hindsight.
How to Draw Downtrends
When a market is in a downtrend, prices should be making lower highs and lower lows. Although prices may rally during the downtrend, they should not break through the previous high. To draw a downtrendline, you start by identifying two consecutive troughs. Then, you connect those troughs with a straight line. The same process confirms the downtrend line when another trough is created.
Identifying and drawing trendlines is an important skill for any trader or investor. By recognizing these patterns in a chart, you can understand the overall market sentiment and make more informed decisions. Understanding trendlines can also help you anticipate future price movements to make better trading and investing decisions.
How to Draw Support & Resistance Lines
It would be best to practice drawing trendlines as much as possible. After a while, you will get used to it, and it will become second nature.
Here is another example of how to draw trendlines. This is a chart of Ticker: AAPL Apple Inc. It shows how to draw trendlines in a downward and upward price move.

How to Practice Drawing Trendlines
Notice that the trendline above the price is called resistance, and the trendline below the price is called support. When the price breaks up through resistance, it moves higher; this could be a buy signal. When the price breaks down through the support trendline, it moves lower; this could be a sell signal.
Quick Tip: The longer the trendline is in place or acts as support or resistance, the stronger the trend and the bigger the move when the trendline is broken.
Look again at Apple Inc.’s chart. See how Apple was in a sideways consolidation from 2001 through 2004. When it eventually broke out of that channel upwards through resistance, the stock took off, making over 1600% gain.
Drawing Trendlines to Recognise Stock Chart Patterns
Trendlines are the foundation of technical analysis. They are used to identify support and resistance levels in a stock or index and chart patterns such as head and shoulders, double tops, triple bottoms, etc.
If you cannot draw a Trend-line you should not invest in the stock market!
In this example, we will examine how to look at price movement and use it to evaluate the stock.
Price is the most critical indicator, so it should be when it boils down to it; the most important thing is the price.
Here, we can see a chart of Broadcom (BRCM), one of the darlings of the tech bubble in 2000.
Where will you draw the trendlines?
Before you scroll down to the chart where I have drawn the trendlines, consider where you would draw them.
Chart with Support & Resistance and a Double Bottom Pattern Trendlines
A chart can come alive when we add trendlines. The graphic below shows a stock with trendlines superimposed.
Follow This Process to Draw the Trendlines
- From left to right, from mid-April to July, the stock begins to move in a sideways pattern, known as “Channeling.”
- The two red lines show the “trading range,” the range between which the stock price fluctuates.
- The upper line is the Ceiling or the “Line Of Resistance,” and the lower line is the Floor or “Support.” Both lines show where the number of sellers equals that of buyers.
- When the stock price falls through the support line, the trend has changed, and the new market impetus affects the stock. If you owned this stock in April and enjoyed the corresponding price rise, this break would be a reliable “Sell Signal” to the trained eye.
- The stock dropped in two days but rose again over the following month to give anyone slow on the uptake another chance to Sell. It broke through the previous support line but was not strong enough to make it to the upper ceiling of the channel. If you had not gotten out this time, you would have suffered a 50% loss—enough to make a grown man weep!
- The next significant point to note is that when the stock bounces at about $13 in mid-October, it is oversold and proceeds to make a very nice-looking “Double bottom“ or “W” bottom.
- Chartists worldwide recognize the double bottom, and those who like to buy on Bottoms would have done so. This happened as the stock moved up 38% in 3 weeks.

Making Buy and Sell Decisions
So we have seen the Sideways Channel and the W bottom. But how do we know when a stock is going to take off?
The truth is we never really know.
All we can do is make judgments based on what we see. Do not forget we are only buying Stocks of companies that have
- Excellent Earnings per Share
- The sharp acceleration in the growth of Earning per Share
- Excellent Revenue growth
So we are, in essence, giving ourselves a great head start and reducing our overall risk.
4-Steps to Use Trendlines for Buy & Sell Decisions
4 Steps to Draw the Trendlines on the Chart
- To evaluate an upward trend, draw a line joining the highest highs
- For the floor of the uptrend, draw a line connecting the lowest lows. The price here bounces three times the bottom trendline but then proceeds higher. The more bounces off a trendline, the stronger the trend.
- A trendline is drawn to show that the price has moved strongly past the previous high; this is a BUY Signal at $35.50.
- Finally, the price is exhausted and falls through the bottom resistance line at $53.
Buying and selling, based on the trendlines here, would have netted you a tasty 49%.

What makes a trendline strong?
A trendline is considered strong when it consistently connects several points on a chart, forming a consistent and reliable pattern. A trendline should also have an adequate number of touches in order to be considered reliable. The more touches on the line, the stronger the trendline.
What are the rules for trendlines?
The most common rules for trendlines are:
- The line should connect two or more points on the chart
- Each time a new point is added, the line should be redrawn to reflect the current trend
- Price should consistently respect a trendline in order for it to be considered reliable
- The more touches on the line, the stronger it is considered to be
- A break of a trendline indicates that the previous trend has ended, and a new one may have started.
When should you add a trendline?
Trendlines should be added when the price action of an asset is clearly moving in a certain direction. This indicates that there is a strong trend that can be used for trading opportunities. It's important to remember that trendlines should not be drawn arbitrarily; they should only be drawn after at least two points have been established and connected with the line.
When should you redraw a trendline?
A trendline should be redrawn when there is evidence that the underlying price action of an asset has changed direction. For instance, if the price breaks through a previously established trend line or fails to reach it in the first place, it may be time to redraw or adjust the trendline.
What happens when a trendline is broken?
When a trendline is broken, it can indicate that the underlying asset price has changed direction. This could lead to potential losses if trades are entered too early without further analysis of the market movement and context. Additionally, it is best practice to wait for some confirmation of the break before making any decisions, as there may be an opportunity to enter into more favorable positions.
