Support and Resistance Levels: Basics and How They Work
Support and resistance levels are one of the key concepts in trading Forex and other financial markets. They are used in various trading strategies and serve as the basis for hundreds of thousands of indicators and trading robots.
So, what exactly are they? Let's explore their basic concepts and various aspects of practical application.
Key Definitions
Support and resistance levels serve as the boundaries of an asset's price range, within which the asset is traded. These boundaries can appear not only as horizontal lines, but also as sloping, curved lines. When these boundaries are reached, the price of the asset often changes its course.
A support level is a price point at which the asset's price is likely to bounce upwards, as bullish buyers try to prevent further declines. On the other hand, a resistance level is a price point where bearish sellers establish control, often causing the price to reverse and fall.
In these definitions, we have intentionally used words like “often” and “may.” This is because a reversal in price at these levels is not guaranteed; they may or may not happen. Instead of bouncing off the support level, the price may break down and fall further, or it may continue its upward momentum after reaching the resistance level. The likelihood of a bounce or breakout helps us classify levels as strong or weak. This will be discussed further in a separate chapter later.
Difference between Support/Resistance Zones and Levels
Whereas support and resistance levels can be visualized as fixed lines on a chart, support and resistance zones represent a range of prices. We believe this is a more accurate idea, because the price rarely changes its direction at a specific point.
For example, the resistance level of the EUR/USD pair may be near the 1.1500 mark. However, the price may move in the opposite direction not only to 1.1500, but also to 1.1485 (before reaching it) or to 1.1515 (a false breakout). This ±15 point gap is what some experts, by analogy with mechanics, call "slack".
The width of the zone (or the size of the slack) may vary depending on the specific asset (in Forex, currency pair) and timeframe. On long-term charts, these zones may be wide, while on short-term charts they are usually narrow. Current volatility also affects this parameter. For example, during the release of major economic news, these zones often widen significantly due to high volatility. We will examine a few examples to illustrate this point.
Currency pairs: For the EUR/USD pair on a daily (D1) chart, the width of the support/resistance zone can range from 20 to 50 points. For the British pound (GBP/USD), which is usually more volatile, this zone can be wider, around 30-60 points. For the USD/JPY pair, the zones were previously relatively narrow, ranging from 15 to 40 points.
However, after 2021, volatility increased sharply due to significant divergences in the monetary policy of the US Federal Reserve and the Bank of Japan, and as a result, the range of support zones for this pair has widened.
Timeframe: Under normal circumstances, on the daily chart (D1), the width of the support/resistance zone is usually between 20 and 60 points, depending on the currency pair. On the hourly chart (H1), these zones can be narrower, ranging from about 10 to 30 points. On very short timeframes (M1-M15), the zones can be narrower, ranging from 5 to 15 points.
Volatility: During times of high volatility, the width of these zones can expand. For example, during the release of economic news, the width of the zone for the EUR/USD pair can be 70-100 points or more.
It is important to remember that these examples serve only as a guide and may change depending on market conditions. Experienced traders usually change their strategy taking into account the current volatility and other factors.
How to identify support/resistance levels
So, from the above discussion, it is clear that the concept of support/resistance actually consists of two components: the level itself and the area around it. Psychological levels such as 1.1000 or 1.5000 often act as support/resistance, as traders prefer to place buy or sell orders near these "round" levels. Additionally, levels with high trading volume often act as support/resistance. This happens because a large number of traders are interested in these levels and are willing to lower the price to complete their trades there.
Levels that have been tested and held repeatedly are considered more reliable. If the price has been around a certain level for several times and failed to break through, then the probability increases that this level will act as a strong resistance or strong support in the future.
So, how are support and resistance levels identified in practice?
The easiest way to identify these levels is through visual analysis of the price chart. Traders look for points where the asset price has stopped and changed direction in the past. These points become potential support or resistance levels. Horizontal lines are often drawn through these points to identify levels. Sometimes, parallel lines are drawn, which create a trading channel within which the asset price fluctuates.
It is worth noting that a trading channel can be horizontal or sloping. Also, the boundaries of this channel can be straight or curved. To make it easier to create levels and channels, the MetaTrader 4 trading terminal offers various charting tools as well as specialized indicators.
Strong and Weak Support/Resistance Levels
What is the difference between strong and weak levels? This question is important for any trader engaged in technical analysis, as understanding these differences can significantly improve the effectiveness of their trading strategy. It helps to avoid false signals and increases the chances of successful trades.
Here are the things that indicate strong levels:
Multiple confirmation: Strong levels are often tested more than once. The more times a level holds and prevents the price from breaking through, the stronger it is considered.
Trading volume: When a strong level is reached, trading volume tends to increase, indicating active interest in that level from a large number of traders.
Historical significance: Strong levels can be identified based on historical data and often correspond to psychological levels (i.e., whole numbers).
Alignment with fundamentals: The strength of a support or resistance level is enhanced when it coincides with key fundamental indicators or news events.
Weak support and resistance levels are usually rarely tested and usually fail to hold the price level. When these levels are reached, the change in trading volume is usually negligible. In addition, they are often not based on historical data and rarely correspond to fundamental market indicators, which makes them more sensitive to market noise.
Indicators for identifying support and resistance levels
Let's list some of the most popular indicators, the workings of which are based on the statistical analysis of past price movements to predict future trends. To increase effectiveness, experienced traders often use these indicators in conjunction with each other or with other technical and fundamental analysis methods and tools.
Moving Average (MA). This indicator combines price data from a specific period of time and smoothes it to identify trends. If the asset price is above the moving average, it can act as a support zone. If it is below, it acts as a resistance zone. For example, the 200-day moving average in an uptrend often acts as a strong support level.
Fibonacci Retracement. This indicator uses the Fibonacci mathematical sequence to create horizontal lines that act as potential support and resistance levels. Lines are drawn through two important points on the chart (high and low) at 23.6%, 38.2%, 50%, 61.8%, and 100%, which serve as potential support and resistance levels.
– Pivot Point (PP). The simplest method of determining pivot points (PP) has been used on Wall Street for decades. The high, low, and closing prices of a given period are taken and divided by 3, which gives the PP value.
Bollinger Bands. This indicator consists of three lines: a middle line (MA) and two outer lines, which are calculated as standard deviations from the middle line. These outer lines act as support and resistance zones. When the asset price approaches the upper line, it may indicate a resistance level; conversely, approaching the lower line may indicate a support level.
Strategy using support/resistance levels:
"Buy low, sell high": Traders buy an asset when its price approaches a support level and sell when the price approaches a resistance level.
"Breakout/Breakdown Trading": In this strategy, positions are entered only when the price strongly breaks through a support or resistance level and stabilizes safely below or above it, respectively.
"Bounce Trading": In this trading method, positions are entered when the price bounces off a support or resistance level.
False Breakout Strategy”: Traders can place buy or sell orders directly at support or resistance levels, expecting a “false breakout”, i.e. a reversal in price.
In conclusion, understanding support and resistance levels and zones, and the ability to identify and apply them correctly, can serve as an effective tool for making profits.
However, like any other trading method in the financial markets, they do not guarantee 100% success and require careful analysis, coordination with other tools, and prudent risk management.
