Not bad! If only one arrow is displayed in an upward or downward "trend", the arrow in the opposite direction will not be displayed until the opposite "trend" appears, even better! That is, the up arrow is displayed, and then the down arrow is displayed. When the market does not have an upward or downward direction, no arrows are displayed.
