Trends, Support & Resistance
How traders map market structure, identify zones, and frame possible continuation or reversal points.
Trend analysis and support/resistance identification are the most foundational concepts in technical analysis. Before applying indicators or chart patterns, a trader needs to understand the directional context of the market and identify the price levels at which buying or selling interest has historically concentrated.
These are not precise, mathematical constructs. They are zones of probability — areas where past market behavior suggests future reactions are more likely.
Key Concepts
An uptrend is characterised by a series of higher highs and higher lows. Each rally reaches a higher peak; each pullback forms a higher trough than the previous one. An uptrend is intact as long as this pattern continues. A downtrend is the mirror image — lower highs and lower lows.
Support is a price level or zone where buying interest has historically been sufficient to halt declines or cause price to bounce. It represents a concentration of demand. When price approaches a known support level, buyers may step in again — making bounces more likely but not certain.
Resistance is the opposite — a price level or zone where selling interest has historically halted advances or caused price to pull back. It represents a concentration of supply. Price approaching resistance tends to face increased selling pressure.
Support and resistance reverse when broken. A level that previously acted as support, once broken decisively, often becomes resistance when price rallies back to it. This 'polarity flip' is one of the most useful and repeatable patterns in technical analysis.
Trend lines connect a series of higher lows in an uptrend or lower highs in a downtrend. They provide a dynamic level of potential support or resistance that moves with the trend. A break of the trend line is often the first signal of potential trend change.
Common Mistakes
Treating support and resistance as exact price points rather than zones. Price often oscillates around these levels rather than reversing precisely at them. Planning for a zone rather than a specific price reduces false signals.
Assuming a break of support automatically signals a new downtrend. False breaks are common, especially around well-known round numbers or widely-watched levels. Waiting for confirmation before acting on a break reduces whipsaw losses.
Overcrowding charts with too many drawn lines to the point where everything looks like support or resistance. The most meaningful levels are those with multiple touches across different time periods.
Key Takeaways
Trends are defined by higher highs/higher lows (up) or lower highs/lower lows (down). Identifying trend direction is the starting point for most technical analysis.
Support and resistance are zones of concentrated demand and supply, not precise price points.
When support breaks, it often becomes resistance. When resistance breaks, it often becomes support.
The quality of a level improves with the number of historical price interactions at that zone.
