Support and resistance lines are technical analysis tools that allow you to interpret the state of the market and its prospects. The support line is the line beyond which the price does not fall. Once the support price is reached, the price reverses its direction and rises again. It’s as if there is an invisible line that ‘supports’ the price and prevents it from collapsing any further. In contrast, the resistance line is made up of a series of price spikes, as if the price was bouncing back to the same area, without ever breaking through the ‘resistance’.
