Understanding Support and Resistance Levels

In the world of trading and investing, understanding how prices move is crucial. One key concept that helps traders predict potential price movements is using support and resistance levels. These levels aren’t magical lines, but rather areas where prices tend to pause, reverse, or have trouble breaking through. They are derived from past price actions and can be valuable tools for making more informed decisions about when to buy or sell an asset.

What are Support and Resistance Levels?

Simply put, a support level is a price point where the price of an asset tends to stop falling and potentially bounce back up. Think of it like a floor that prevents the price from dropping further. This happens because, at that price, there tends to be more buying pressure than selling pressure, as investors see the price as a good value. On the other hand, a resistance level is a price point where the price of an asset tends to stop rising and potentially fall back down. It’s like a ceiling that the price struggles to break through. At this level, there is usually more selling pressure than buying pressure, as investors may see the price as too high.

How Support and Resistance Form

Support and resistance levels are not precise single prices, instead, they’re more accurate to think of as zones or areas in which the probability of the price reversing increases. These levels form due to the collective psychology of the market participants. When a price falls to a certain point and then bounces back up several times, it creates a strong support level. Likewise, when the price rises to a certain point and falls back several times, it establishes a strong resistance level.

These patterns emerge because traders and investors remember previous price activity. For example, if a stock price has repeatedly fallen when it reached $50, each time the price approaches that level again, there will likely be increased selling as people who previously saw the stock fall from $50 may sell or short the stock to lock in profits or speculate on another drop. That’s how patterns develop and support and resistance levels are formed. The more times that the price bounces off a certain level, the stronger the support or resistance level tends to be.

Identifying Support and Resistance

Identifying support and resistance is done by analyzing price charts. Here are some key ways to do it:

• Look for Price Bounces: Look for areas on the chart where the price has repeatedly bounced off of a single approximate level. The more times it has bounced off the approximate level, the stronger that level may be in the future.
• Previous Highs and Lows: Past highs often become resistance levels, and past lows tend to become support levels. Think of it this way: previously, when prices fell to a low point, the price was then considered a better value (and therefore more buyers entered the market and the price rose). Similarly, when the price reached highs previously, it may have been considered to be too expensive (and therefore more sellers entered the market and the price fell).
• Trend Lines: These are lines that connect a series of highs or lows. An upward slanting line connecting lows act as a support line, while a downward slanting line connecting highs acts as a resistance line.
• Psychological Levels: Round numbers like $10, $50, $,100, etc., often act as psychological support or resistance levels because they are easily remembered and used by investors.

Keep in mind that these levels are not always perfect, and prices can sometimes slightly break them before reversing or moving through them. Looking at price charts over a longer time period (for example, 1 year vs 1 week) will likely uncover levels that are stronger due to their history.

Trading with Support and Resistance

Support and resistance levels can be used in several ways in trading. Here are the most common ones:

• Buying at Support: A common strategy is to buy an asset when its price reaches a support level with the expectation that the price is likely to bounce back upward. For safety, investors may wait for confirmation of the price movement (for example, a strong green candle that forms after touching the support).
• Selling at Resistance: Conversely, traders may sell an asset when its price reaches a resistance level, expecting the price to fall back down. As with the purchase action, traders may also require confirmation before selling (for example, a strong red candle after touching the resistance level).
• Breakouts: Sometimes, the price breaks through a support or resistance level and continues in the new direction. This is called a breakout. Traders often use breakouts as signals to enter their positions in the direction of the breakout. For instance, if the price breaks a resistance, and the resistance has become a new support, traders might buy expecting a sustained price rally.
• Fakeouts: There are also occurrences called fakeouts, where prices appear to break a support or resistance, only to fall or rise suddenly in the opposite direction. Support and resistance levels are guidelines, not guarantees.

It is important to note that confirmation of a price reversal is better than anticipating it (or trying to “catch a falling knife”). There is a risk when purchasing stock near support levels because there is a chance that the level will not hold. Therefore, waiting to see if a reversal occurs adds an extra level of safety for traders. Waiting to see if resistance levels hold before selling also adds a level of safety to potentially more speculative sales actions. Some traders may even add trading confirmation tools or chart patterns to their buying and selling decisions. These may include tools like MACD or RSI indicators, or chart patterns such as cup and handle or pennant patterns, respectively.

Role Reversal

One of the interesting characteristics of support and resistance levels is that they often switch roles. When a price breaks through a resistance level, that level can become a new support level. Similarly, a broken support level can eventually become a new resistance level. Think of it as a ceiling becoming the new floor, or a floor becoming the new ceiling. The rationale is that once a level is breached, market participants tend to view it differently, and that change in psychology often leads to the previous wall becoming the new floor and vice versa.

Limitations of Support and Resistance

While support and resistance are powerful tools, it’s important to understand their limitations:

• Not Exact Sciences: These levels are not exact lines, these zones can be broken and become unreliable and need to be refreshed with information from the latest price action.
• Subjectivity: Drawing these levels can sometimes be subjective, as different traders might interpret the charts slightly differently. There is often interpretation involved, and that interpretation of the levels may change overtime as the price chart has been updated with more data.
• Not Foolproof: Market reactions to levels are not always consistent, and prices can sometimes make a sudden move that breaks through expected levels. It’s essential to use these levels alongside other analysis tools.
• Market Changes: A support or resistance level that has held true for an extended period may suddenly fail during times of dramatic economic or market changes.

Conclusion

Support and resistance levels are valuable tools derived from analyzing past price movements. They can provide important insights into potential buying and selling points. However, these levels should be used as an aid and alongside other types of technical analysis tools and analysis. These levels are often not exact and can fail at any time. By using them wisely, you can significantly enhance your understanding of price behavior and potentially make more informed decisions in your trading or investment strategies. Keep in mind that practice is essential to recognizing and using these levels effectively.
