What Are Trendlines and Support/Resistance Levels?


Most experienced traders can share stories about how certain price levels tend to stop traders from pushing the worth of an underlying asset during a certain direction. For example, assume that Jim was holding an edge available between March and November which he was expecting the worth of the shares to extend.

Let’s imagine that Jim notices that the worth fails to urge above $39 several times over several months, albeit it’s gotten very on the brink of moving above that level. In this case, traders would call the price level near $39 a level of resistance. As you’ll see from the chart below, resistance levels also are considered a ceiling because these price levels represent areas where a rally runs out of gas.

Support levels are on the opposite side of the coin. Support refers to prices on a Chart that tend to act as a floor by preventing the worth of an asset from being pushed downward. As you can see from the chart below, the ability to identify a level of support can also coincide with a buying opportunity because this is generally the area where market participants see value and begin to push prices higher again.


The examples above show a continuing level prevents an asset’s price from moving higher or lower. This static barrier is one among the foremost popular sorts of support/resistance, but the worth of monetary assets generally trends upward or downward, so it’s not uncommon to see these price barriers change over time. This is why the concepts of trading and trendlines are important when learning about support and resistance.

When the market is trending to the upside, resistance levels are formed because the price action slows and starts to maneuver back toward the trendline. This occurs as a results of profit-taking or near-term uncertainty for a specific issue or sector. The resulting price action undergoes a “plateau” effect, or a slight drop-off in stock price, creating a short-term top.

Many traders will pay close attention to the price of a security as it falls toward the broader support of the trendline because, historically, this has been an area that has prevented the price of the asset from moving substantially lower. For example, as you’ll see from the Newmont Mining Corp chart below, a trendline can provide support for an asset for several years. In this case, notice how the trendline propped up the worth of Newmont’s shares for an extended period of your time .

On the opposite hand, when the market is trending to the downside, traders will await a series of declining peaks and can plan to connect these peaks along side a trendline. When the worth approaches the trendline, most traders will await the asset to encounter selling pressure and should consider entering a brief position because this is often a neighborhood that has pushed the price downward in the past.

The support/resistance of an identified level, whether discovered with a trendline or through any other method, is deemed to be stronger the more times that the price has historically been unable to move beyond it. Many technical traders will use their identified support and resistance levels to settle on strategic entry/exit points because these areas often represent the costs that are the foremost influential to an asset’s direction. Most traders are confident at these levels within the underlying value of the asset, therefore the volume generally increases quite usual, making it far more difficult for traders to continue driving the price higher or lower.

Round Numbers

Another common characteristic of support/resistance is that an asset’s price may have a difficult time moving beyond a round number, such as $50 or $100 per share. Most inexperienced traders tend to buy or sell assets when the price is at a whole number because they are more likely to feel that a stock is fairly valued at such levels. Most target prices or stop orders set by either retail investors or large investment banks are placed at round price levels instead of at prices like $50.06. Because numerous orders are placed at an equivalent level, these round numbers tend to act as strong price barriers. If all the clients of an investment bank put in sell orders at a suggested target of, for example, $55, it would take an extreme number of purchases to absorb these sales and, therefore, A level of resistance would be created.

Moving Averages

Most technical traders incorporate the facility of varied technical indicators, like moving averages, to assist in predicting future short-term momentum, but these traders never fully realize the power these tools have for identifying levels of support and resistance. As you can see from the chart below, a moving average is a constantly changing line that smooths out past price data while also allowing the trader to identify support and resistance. Notice how the worth of the asset finds support at the moving average when the trend is up, and the way it acts as resistance when the trend is down.

Traders can use moving averages during a sort of ways, like to anticipate moves to the upside when price lines cross above a key moving average, or to exit trades when the worth drops below a moving average. no matter how the moving average is employed , it often creates “automatic” support and resistance levels. Most traders will experiment with different time periods in their moving averages in order that they will find the one that works best for this specific task.

Other Indicators

In technical analysis, many indicators are developed to spot barriers to future price action. These indicators seem complicated initially , and it often takes practice and knowledge to use them effectively. no matter an indicator’s complexity, however, the interpretation of the identified barrier should be consistent to those achieved through simpler methods.

Measuring the importance of Zones

Remember how we used the terms “floor” for support and “ceiling” for resistance? Continuing the house analogy, the safety are often viewed as a rubber ball that bounces during a room will hit the ground (support) then reboundoff the ceiling (resistance). A ball that continues to bounce between the ground and therefore the ceiling is analogous to a trading instrument that’s experiencing price consolidation between support and resistance zones.

Now imagine that the ball, in mid-flight, changes to a ball . This extra force, if applied on the high , will push the ball through the resistance level; on the way down, it’ll push the ball through the price . Either way, extra force, or enthusiasm from either the bulls or bears, is required to interrupt through the support or resistance.

A previous price will sometimes become a resistance level when the worth attempts to maneuver copy , and conversely, a resistance level will become a price because the price temporarily falls back.

Price charts allow traders and investors to visually identify areas of support and resistance, and that they give clues regarding the importance of those price levels. More specifically, they appear at:

  1. Number of Touches

The more times the worth tests a support or resistance area, the more significant the extent becomes. When prices keep bouncing off a support or resistance level, more buyers and sellers notice and can base trading decisions on these levels.

  • Preceding Price Move

Support and resistance zones are likely to be more significant once they are preceded by steep advances or declines. for instance , a fast, steep advance or uptrend are going to be met with more competition and enthusiasm and should be halted by a more significant resistance level than a slow, steady advance. A slow advance might not attract the maximum amount attention. this is often an honest example of how market psychology drives technical indicators.

  • Volume at Certain Price Levels

The more buying and selling that has occurred at a specific price index , the stronger the support or resistance level is probably going to be. this is often because traders and investors remember these price levels and are apt to use them again. When strong activity occurs on high volume and therefore the price drops, tons of selling will likely occur when price returns thereto level, since people are much more comfortable closing out a trade at the breakeven point instead of at a loss.

  • Time

Support and resistance zones become more significant if the amount are tested regularly over an extended period of your time .


Support and resistance levels are one among the key concepts employed by technical analysts and form the idea of a good sort of technical analysis tools. the fundamentals of support and resistance contains a price , which may be thought of because the floor under trading prices, and a resistance level, which may be thought of because the ceiling. Prices fall and test the price , which can either “hold,” and therefore the price will recover up, or the price are going to be violated, and therefore the price will drop through the support and certain continue lower to subsequent price .

Determining future levels of support can drastically improve the returns of a short-term investing strategy because it gives traders an accurate picture of what price levels should prop the worth of a given security within the event of a correction. Conversely, foreseeing A level of resistance are often advantageous because this is often a price index that would potentially harm an extended position, signifying a neighborhood where investors have a high willingness to sell the safety . As mentioned above, there are several different methods to settle on when looking to spot support/resistance, but no matter the tactic , the interpretation remains the same—it prevents the worth of an underlying asset from occupation a particular direction.
