Bar Type	Choose the type of bar if applicable, either High Low Bar, Candlestick, Hollow Candles or Heikin-Ashi. The Hollow Candles display green unfilled candlesticks when that period's close is higher than its open. The Heikin-Ashi candles use the open-close data fro the prior period with the open/high/low/close data from the current period to create a combo candlestick. Note that selections will be grayed out when unavailable, based on other time period selections.
Volume Plot Height	This applies to the plot height of additional plots such as Volume.
Adjust for Dividends	When checked, prices are adjusted for dividends on the chart. The day before the dividend date the dividend amount is subtracted from the close price. This action is completed automatically if you add a second ticker for comparison to the chart.
Show # bars	Enter the number of bars to display on the chart, and check to enforce this attribute. When checked, the number of bars remains consistent regardless of changes to the Time period or other variables.
Manual Vertical Scale	Define a price range to scale the vertical axis for the chart. If checked, click the yellow lock icon that will appear in the chart to re-enable auto-scaling.
