Why do support and resistance work?

Many traders watch the same levels and place orders around them, and holders who bought near a level often sell when the price returns there to break even.

What happens when support breaks?

A broken support level often becomes resistance later, because buyers who were trapped below it use any return to that price to get out.

What Are Support and Resistance Levels?

Q: What are support and resistance?

Support is a price area where buying has repeatedly stopped a fall; resistance is an area where selling has repeatedly stopped a rise. They are zones rather than exact prices.

Prices don't move in a straight line — they tend to stall at certain levels over and over. Learning to spot those levels is one of the first real skills in reading a chart.

Support is a price level where an asset has historically tended to stop falling and bounce back up, as buying interest repeatedly outweighs selling pressure at that point. Resistance is the mirror image — a level where price has repeatedly struggled to break higher, as selling pressure repeatedly overwhelms buyers there.

These levels form because market participants remember them. Traders who missed buying at a previous low often place orders to buy if price returns to that level, and traders sitting on a position from a previous high often look to sell if price gets back there — both behaviors reinforce the same levels over time, which is why they tend to matter even without any fundamental reason attached to that exact price.

Levels aren't permanent, though. When a price finally pushes through a resistance level with real conviction, that same level often flips into new support going forward — the logic being that everyone who wanted to buy below resistance and missed it now treats a pullback to that level as a second chance.

Spotting these levels is easiest directly on a candlestick chart, watching where price has repeatedly reversed in the past. Trade2Spike's live charts make it possible to mark those zones on real, currently-moving prices — a much more useful way to build the skill than studying levels on a static screenshot after the fact.
