If you've spent time looking at a price chart, you've probably noticed something curious. Prices don't move in straight lines. They tend to stall, bounce, or reverse at certain price levels repeatedly, almost as if there's an invisible floor or ceiling. That's not a coincidence. It's one of the oldest and most reliable concepts in technical analysis: support and resistance.
Whether you trade stocks, forex, crypto, or commodities, understanding support and resistance is often the first real skill that separates someone reading charts from someone who understands them.
Here's how support and resistance work and how traders use them:
Support is a price level where a downtrend tends to pause or reverse because buying interest becomes strong enough to overcome selling pressure. Think of it as a "floor" that the price has trouble falling through.
Resistance is the opposite. It is a price level where an uptrend tends to stall or reverse because selling pressure overwhelms buying interest. It acts like a "ceiling" that the price struggles to break above.
