Simply put, an area of support is where the price of an asset tends to stop falling, and an area of resistance is where the price tends to stop rising. But traders really need more information about support and resistance beyond those simple definitions before they attempt to make trading decisions based on those areas in a chart.
To use support and resistance effectively, you first need to understand how asset prices typically move, so you can then interpret support and resistance from that framework. You also need to be aware that there are different types of support and resistance, such as minor and major/strong. Minor levels are expected to be broken, while strong levels are more likely to hold and cause the price to move in the other direction.
