Chart Parameters

Instructions

You can set chart parameters when you open a chart, and modify parameters from within a chart by taking the steps outlined below.

Click the Edit button at the top of the Chart window.
Select Chart Parameters
The Chart Parameters window will open allowing you to configure.

Field	Description
Time Period	Choose a time period and interval along with the denomination of bar or line for the chart. If you select an Automatic chart, you are selecting only the interval and denomination. You will be able to modify the time period using the drag bar within the chart. Click the Customize Menu link to define custom time periods/intervals.
What to show:	Choose the primary display: Trades, Midpoint, Bid/Ask, Option Volume, Historical Volatility, Option Implied Volatility, Option Open Interest.
Bar Type	Choose the type of bar if applicable, either High Low Bar, Candlestick, Hollow Candles orHeikin-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.

Additional Data and Features

Additional data shown in your chart parameters box is dependent on the selections you set as the primary parameters. The table below lists all potential options. Because they are context-sensitive, you won’t see all of them at the same time.

Field	Description
Bid/Ask or Midpoint or Trades	Shows a secondary plot along with your primary plot. Display will change based on your primary plot, i.e. if you show Trades as the primary, your options will include Bid/Ask and Midpoint.
Volume	Shows the daily trading volume in a separate panel below the chart.
Volume Histogram	Shows the daily trading volumes at each price point in a separate area of the chart.
Daily P&L	Displays daily profit and loss for the contract.
Total call and put value	For option settings such as open interest and volume, check to display the total value for calls and puts.
Option volume	Charts call and put volume in the Option Volume sub-chart.
Historical volatility	Displays actual historical volatility.
Option implied volatility	Charts implied volatility in a Volatility sub-chart.
