Support and resistance levels play crucial roles in many day trading strategies. For instance, you can use resistance levels to spot a breakout in progress. You can also trade stocks as they oscillate between support and resistance zones. These levels help traders plan profit targets and stop losses for their positions.
Day traders must quickly identify support and resistance levels in their trading. We’ll explain what these levels are, why they matter, and how to locate them on technical charts.
What are Support and Resistance Levels?
Support and resistance levels are price points that a stock struggles to break through.
A support level occurs below a stock’s current price. It forms because each time the stock’s price drops to this level, buyers step in. This prevents further declines and often pushes the price back above the support level.
A resistance level occurs above a stock’s current price. When the stock reaches this level, traders or investors sell their shares, preventing the price from rising further.
Support and resistance levels don’t last forever. When a support level breaks – meaning the price falls below it – that level often becomes a new resistance area. Similarly, when a resistance level breaks – meaning the price rises above it – that level typically becomes new support.
Support and resistance levels vary significantly in strength and durability. One resistance level might be tested dozens of times over many months before breaking. Another might be touched a few times and then quickly breached. Generally, the stronger a resistance level was before breaking, the more durable it becomes as future support. The same principle applies to support levels.
Why are Support and Resistance Levels Important?
Support and resistance levels are vital to traders for several key reasons.
First, they form the foundation of many trading strategies and technical setups. Numerous trades center around breakouts above resistance levels or breakdowns below support levels. Traders use these levels (alongside other technical indicators) to time their entry and exit points.
Additionally, support and resistance levels help traders assess potential risk and reward. If you’re entering a bullish position 3% above a support level and 7% below a resistance level, you can estimate your trade carries approximately 3% risk and 7% reward potential. You might use the support level as your stop loss and the resistance level as your profit target.
How to Find Support and Resistance Levels
Several methods exist for identifying support and resistance levels on technical charts.
Static Prices
The first type is static support and resistance. These levels remain constant as new data emerges (unlike dynamic levels discussed next).
Static price levels can be psychological or specific to a stock’s trading history.
Round-number prices like $100 or $150 – or $1 or $1.50 for penny stocks – frequently act as support and resistance levels.
This phenomenon is largely psychological. Traders notice a stock reaching a price like $100 and react by buying or selling. These prices are often visible on chart y-axes, and many trading platforms include horizontal lines at these levels by default.
Static prices typically create weak support and resistance areas initially, but they can strengthen if tested multiple times without breaking.
Stocks may also develop static support and resistance levels visible through chart analysis. These are prices where a stock has previously bounced. For instance, if a stock consistently rebounds from $44 during pullbacks after uptrends, $44 likely represents a support zone.
Trend Lines
While static support and resistance levels appear as horizontal lines on charts – maintaining the same price – trend lines are diagonal. This means the specific support and resistance prices change over time.
Consider a stock with an upward-trending price pattern featuring multiple oscillations. You might connect each oscillation’s low point with an upward-trending trendline. This trendline indicates rising support levels with each oscillation, potentially helping predict the next low in the stock’s movement.
Technical Indicators
Popular technical indicators plotted alongside price data can also reveal support and resistance levels. Many day traders use volume-weighted average price (VWAP) to identify levels on intraday charts or moving averages to spot levels on daily charts.
These indicators calculate from a stock’s price movements rather than being manually drawn like trendlines. This can make them more straightforward to use, though remember that various timescales and factors influence VWAP and moving average calculations (such as simple versus exponential moving averages).
Additional Considerations
Before trading around support and resistance levels, consider several important factors.
Always examine support and resistance levels across multiple chart timeframes. The strongest levels typically appear consistently across different timeframes.
For example, an intraday support level might seem insignificant when viewing only 1-minute and 30-minute charts. However, if that support level coincides with the 200-day moving average on the daily chart, it’s likely very strong.
Remember that support and resistance levels aren’t precise. A stock might have support around $100, but the price can still drop to $99.99 without truly “breaking” support.
When trading around these levels, confirm that breakouts are genuine before entering positions. If using support and resistance levels for stop losses, allow some buffer below support or above resistance levels.
Finally, remember that support and resistance levels can break. While these levels are difficult to breach, they’re not guaranteed to hold. Many traders build entire strategies around moments when support and resistance levels fail.
When a stock breaks through its support or resistance level, don’t assume it’s temporary. This could signal a significant trend change. However, many breakouts also fail, so consider other technical indicators when deciding your response.
Conclusion: Support and Resistance In Day Trading
Support and resistance levels are essential for day traders because they form the foundation of trading strategies and help assess risk-reward ratios. These levels commonly occur at round-number prices or follow trendlines tracking price highs and lows. They can also appear around popular technical indicators like moving averages and VWAP.
When trading around support and resistance levels, remember they can fail. When breakouts occur, evaluate whether they’re sustained and prepare to respond to potential trend reversals.
