Support is a price level where buying pressure historically exceeds selling pressure, causing price to bounce. Resistance is a price level where selling pressure exceeds buying pressure, causing price to reverse. Once broken, support becomes resistance and vice versa.
Support and resistance are the most fundamental concepts in technical analysis. They represent psychological and practical price levels where market participants consistently make buying or selling decisions.
**Why support and resistance form:** - **Round numbers**: Psychological significance (e.g., $100, $1,000, $10,000 for Bitcoin) - **Previous highs and lows**: Natural reversal points where traders enter or exit - **Moving averages**: Dynamic support/resistance that moves with price - **Volume nodes**: High-volume areas where many participants have positions to protect - **Fibonacci levels**: Mathematically derived retracement levels
**Support/resistance flip:** When a support level is broken with conviction (high volume, full candle close below), it typically becomes resistance. This "polarity flip" is one of the most reliable and tradable phenomena in technical analysis.
**Strength factors:** - How many times the level has been tested (more touches = stronger level) - How long ago the level was formed (recent levels are more relevant) - Whether the level was tested on high or low volume - Whether the level aligns with other indicators (Fibonacci, moving average, POC)
**In crypto context:** Crypto markets respect round numbers more dramatically than traditional markets due to high retail participation. Bitcoin's all-time highs consistently become support after being broken above. Altcoin support/resistance levels are often less reliable due to lower liquidity and higher manipulation risk.

Frequently Asked Questions
How do you identify strong support and resistance levels?
Look for price levels that have been tested multiple times, where the tests occurred on high volume, and that align with other technical factors (Fibonacci levels, moving averages, volume POC). The more confluence, the stronger the level.
What does it mean when support becomes resistance?
When price breaks below a support level, that same level often repels future rallies from below. This happens because traders who bought at support are now underwater and will sell if price returns to their entry — turning the old support into a supply zone.
Are round number price levels important in crypto?
Yes — perhaps more so than in traditional markets. Bitcoin at $100K, $50K, $30K all acted as major psychological turning points. Retail traders and algorithms cluster orders at round numbers, creating self-fulfilling support/resistance zones.

Fibonacci Retracement
Fibonacci retracement is a technical analysis tool that uses horizontal lines at key ratios (23.6%, 38.2%, 50%, 61.8%, and 78.6%) derived from the Fibonacci sequence to identify potential support and resistance levels where price may reverse during a pullback.
Volume Profile
Volume Profile displays trading volume distributed across price levels over a specified time period, showing where the most and least trading activity has occurred. High-volume nodes act as strong support/resistance; low-volume nodes (gaps) act as areas where price moves quickly.
Market Structure
Market structure refers to the pattern of higher highs and higher lows (uptrend), lower highs and lower lows (downtrend), or equal highs and lows (range) formed by price action. It is the foundational framework for understanding trend direction and identifying when trends shift.
Supply and Demand Zones
Supply and demand zones are price areas on a chart where significant institutional buying (demand) or selling (supply) previously occurred, causing a strong price move away from that zone. When price revisits these zones, it often reverses because the unfilled orders from the original move still exist.
