Dotted line/Price Movement
When looking at the stock graph with the 1-day range selected, a dotted line will appear across the graph. This line represents the previous day's closing price.
The current day's price may fluctuate above or below the dotted line. As it does, the graph's color will change to green (above the line) or red (below the line) to help visualize the current price movement.
The current day can start above or below the previous day's close. This is because of changes to the stock price during previous day after-hours or current day pre-market trading.
The price change for the day is calculated by looking at the difference between the previous day's close and the current day's close. After-hours trading does not count.
Changing the timespan
The buttons are centered and just below the price graph. They are green or red depending on the price movement.
The buttons are left-aligned and below the price graph. They are shown as white text but the selected range is colored green or red depending on the price movement.
