Support

Support is a price point where an asset is expected to have significant demand. This indicates that it is unlikely for the price to go below this level. Support can be assessed by looking at an order book. Price levels with a large quantity of pending buy orders would be deemed support levels.

Additionally, support can be determined by historical price moves. Support can be a constant price, or it can be a trendline that is increasing or decreasing over time. Support is a common decision variable for active traders.
