Strong levels of support occur in places where a large number of large buy orders are concentrated. The same is with the resistance level, which is determined by the presence of a significant list of sell orders. One of the main definitions that traders face is the trend and trend movement of prices. A trend in itself is just a channel made up of parallel resistance / support lines.
The direction of the trend movement is determined by the slope of the lines. If they are directed up, then the trend is called upward. This means that cryptocurrency trading is dominated by purchases. For a downtrend, the opposite is true. A side trend (or flat) is a movement in which resistance / support lines are horizontal and approximate equality of sales and purchases is observed.
