Learn to identify the price levels where stocks consistently reverse or consolidate — and how to trade breakouts and role reversals.
Support is a price level where buying interest is strong enough to halt a decline and push prices back up. Think of it as a floor — every time the price falls to this level, buyers show up.
Resistance is a price level where selling pressure is strong enough to halt a rise and push prices back down. Think of it as a ceiling — every time the price rises to this level, sellers show up.
Buyers believe the stock is undervalued at this price and step in. Each test of support that holds reinforces the level's significance. The more times price bounces from a level, the more market participants are watching it.
Sellers believe the stock is overvalued at this price and exit or short. Each rejection at resistance reinforces the level. This includes buyers who got stuck at previous highs and are waiting to break even before selling.
Why do these levels form? Because humans have memory. Traders remember where price reversed before, and they set orders around those same levels — creating self-reinforcing price behavior.
Use these five methods to locate S/R levels on any chart. The strongest levels are confirmed by multiple methods simultaneously.
The most fundamental S/R source. A prior high becomes future resistance; a prior low becomes future support. The more significant the swing (the more price moved from it), the stronger the level.
Stocks often find S/R at psychologically significant levels — $50, $100, $200, $1,000. Large options strikes cluster here, and many traders set limit orders at round numbers, creating self-fulfilling price behavior.
Where the most trading has historically occurred, often visible as consolidation zones. High volume means many participants traded at that price and have a reference point — they'll act again when price returns.
Price gaps (where the stock opens significantly above or below the prior close) often leave empty air that price wants to 'fill' later. The bottom of a gap-up becomes support; the top of a gap-down becomes resistance.
The 20-, 50-, and 200-day moving averages act as dynamic (moving) support and resistance. Prices in strong uptrends regularly bounce from the 50-day MA. We cover MAs in depth in Lesson 4.
This is one of the most powerful and reliable concepts in all of technical analysis. When a significant support level is broken, it often flips to become resistance on the next rally — and vice versa.
Trend lines are diagonal support/resistance lines drawn by connecting a series of swing lows (in an uptrend) or swing highs (in a downtrend). They show the pace of the trend, not just its direction.
Connect at least two significant swing lows with a rising straight line. The more touches without a break, the more reliable. Drawn from bottom-left to top-right.
Connect at least two significant swing highs with a declining straight line. Each rejection at the line confirms its validity. Drawn from top-left to bottom-right.
Draw both an uptrend line (connecting lows) and a parallel line along the tops. Price oscillates between them. Channels are excellent for timing entries (at the lower line) and exits (at the upper line).
A breakout occurs when price moves decisively beyond a support or resistance level. Breakouts can be the beginning of powerful moves — but false breakouts are extremely common and catch many traders off guard.
Professional tip: rather than buying on the initial breakout, many experienced traders wait for a pullback to the broken level (the retest). If it holds, that's a higher-probability entry with a clear and nearby stop-loss level.
A stock repeatedly bounces off the $150 price level during a downtrend. What does this indicate?
A stock breaks decisively below a support level that had held for six months. What often happens to that level afterward?
Which factor best indicates that a breakout above resistance is genuine rather than a false breakout?
