• A histogram visually displays the opening, high, low and closing prices of an asset or security over a specific period of time.

  • The vertical line on the price bar represents the high and low prices for the period.
  • The left and right horizontal lines on each price bar represent the opening and closing prices.
  • Histograms can be color-coded, where if the close is higher than the open, it can be colored black or green, and if the close is lower than the open, the bar can be colored red.
