In this bar chart, why are down ticks sometimes colored green, and up ticks colored red?
The explanation says "A bar is shown in the "up-tick" color if the current close price is higher than the previous close. Conversely, if it is lower, the bar is displayed in the "down-tick" color."
I'm not sure I understand this explanation. What does "current close price" refer to? How does the coloring scheme work here?
