The Formula function is simple, powerful, and flexible.  The function string is comprised of required elements as well as optional elements.

=ICEFormulas(<Array of Descriptions>,<Array of Formulas>,Granularity (Daily if omitted),Start Date, End date, Index)

The array of descriptions or formulas must be a range in Excel (for example: A1:A20).

Granularity can be set as follows:

"I" Minute Granularity
"I60" Hourly Granularity
"D" (or omitted) Daily Granularity
"W" Weekly Granularity
"M" Monthly Granularity

Date ranges and index work as follows:

Start Date Only Returns that date only
End Date Only Returns that date only
Start Date & Index Returns index values after that start date
End Date & Index Returns index values before that end date
Start Date & End Date Returns the values between those two dates
Index Only Returns the most recent values
Start Date & End Date & Index Returns the values between those two dates and disregards the index value

Optional Elements

Plot= Vertical returns a vertical plot, Horizontal (or omitted) returns default horizontal plot
UseReference= False turns off any cell referencing, True (or omitted) returns default cell referencing
Sort= Ascending returns ascending dates, descending (or omitted) returns descending dates
Fill= FillForward fills blank values from previous values, FillBackwards fills blank values from later values, and Interpolate fills blanks as a line between existing values.  Omitting any fill options will show blanks as default.
TimelineMerge= U returns the union of dates when any symbol returns values, I returns the intersection when all symbols return values, R uses the timeline from the first symbol in the list, and omitting any timeline merge option will show the default calendar option.
Seasonality= True returns the output in a seasonal view, false (or omitted) returns the default output
DayOfWeek= Days of the week can be shown or filtered using the corresponding number 1= Monday and 7 = Sunday.  Omitting this shows the entire week.
