Support and resistance are fundamental price levels on a chart where buying or selling pressure is historically concentrated, causing price to pause, reverse, or consolidate. Support is a price level where buying pressure historically stops a decline – the market supports price from falling further. Resistance is a level where selling pressure stops a rise – the market resists further advances. These levels form because of trader psychology: people who bought at $30,000 want to sell when price returns to their cost basis (resistance); those who missed buying at $30,000 buy when price retests that level (support). Key properties: previous support becomes resistance after a breakdown (flipped support) and vice versa; round numbers (Bitcoin at $100K, $50K, $30K) act as psychological support/resistance; all-time highs are major resistance until broken; and high-volume price nodes create strong support/resistance zones. Identifying support and resistance requires studying multiple time frames – daily and weekly levels carry more weight than hourly. These zones are not precise lines but ranges where price reaction is more likely.
Example: Example: Bitcoin $20,000 was its previous ATH (December 2017). After breaching $20K in December 2020, it acted as strong support throughout 2021. When it broke down below $20K in June 2022, the former support became resistance – Bitcoin struggled to reclaim $20K for months. This support-becomes-resistance flip is one of the most reliable patterns in technical analysis.
