What are support and resistance levels?
In technical analysis, support and resistance are key price zones where the market tends to react.
- Support is a price area where buying pressure prevents further decline.
- Resistance is where selling pressure halts upward movement.
They represent market psychology. Traders buy at support because they perceive value, and they sell or take profits at resistance because they see overvaluation. Identifying these zones helps find entry and exit points with higher probability of success.
How to identify them
There are several techniques to spot these levels:
- Horizontal zones: drawn where price has reacted multiple times in the past.
- Trendlines: upward ones act as dynamic support; downward ones as resistance.
- Moving Averages: common ones like EMA 50 or EMA 200 often act as dynamic levels.
- Psychological levels: round numbers (e.g., 1.0000 or 10,000) often attract order flow.
- Volume confirmation: spikes in volume reinforce the importance of the zone.
How price reacts at these level
When price reaches a support or resistance, three outcomes are common:
- Bounce: price reverses direction from the level.
- Breakout: price breaks through decisively, suggesting continuation.
- Fakeout: a false breakout where price briefly pierces the level and reverses hard.
Confirmation is essential — traders use volume, candle closes, or structure shifts before entering.
Practical application
Traders use support and resistance to:
- Enter trades near key levels to catch reversals.
- Trade breakouts when price moves with volume beyond a key level.
- Set Stop Loss and Take Profit: below support for buys, above resistance for sells.
- Confirm trend shifts: when an old support turns into resistance (or vice versa), confirming a change of polarity.
Common mistakes
- Drawing too many levels, cluttering the chart.
- Treating them as exact prices rather than zones.
- Entering trades without confirmation.
- Ignoring overall market trend and higher timeframe context.
