Red Vertical Arrow for Up and Down Directions

This graphic displays a prominent red vertical arrow, designed to show movement or direction in both upward and downward senses simultaneously. The arrow is flanked on its sides by two dashed lines, formed by a series of small red dots. At the top and bottom of the frame, there are thick, rounded horizontal red lines, enclosing the central arrow and suggesting a defined range or boundary. It's a straightforward symbol often used to represent vertical measurement, height adjustments, or dual directional flow.
