 Spreadsheet Example Formulas and Usage
On This Page
Introduction
This documentation page documents all of the available Spreadsheet functions.
Spreadsheet functions are entered into cells. They take parameters and data, make calculations on the parameters and data, then return the result to the same cell they are entered in.
External Function Reference
For more detailed information about any of the Spreadsheet functions documented on this page, refer to the Microsoft Excel Function Reference.
Using Spreadsheet Functions
To use a Spreadsheet function, use the = sign to indicate a formula, enter the function name, then enter the parameters and data enclosed in parentheses (). Separate each parameter with a comma ",". The formula does not only have to contain a single function, it can contain anything that can be part of a formula as described on the Working with Spreadsheets documentation page.
Spreadsheet function parameters can be Numbers, Cell and Range References, Other Functions, Text Strings (the text needs to be in quotation marks), Dates and Times, Logical Values (TRUE, FALSE), and Error Values.
Any of these types can be used as a parameter as long as they are compatible with or can be converted to the parameter type specified in the function format in the list of Spreadsheet Functions. Parameters can also use operators. Use a cell or range reference as a parameter or as part of an expression, if you want to use data for a function parameter that is located in a cell or a range.
Examples:
=SQRT(4) This function can be entered in any cell and will return 2.
=SQRT(B1) Returns the square root of the value in cell B1.
=SQRT(4+B1) Returns the square root of 4 plus the value in cell B1. The parameter to this function is called an Expression.
=SUM(F4:F24) Returns the sum of cells F4 through F24.
The format for some functions specify an Expression. An expression is just like a formula. Except that it is not prefixed with an =. Therefore, anything you can use in a formula can be used in an expression. See the Working with Spreadsheets documentation page for information on formulas and expressions. The simplest form of an expression is a single number ( Example: 5). A logical expression is one that returns TRUE if it evaluates to a nonzero number and returns FALSE if it evaluates to 0.
If the function format shows a parameter in brackets ([ ]), then that parameter is optional.
When a parameter specifies a list, then use a reference to a range or a comma separated list.
A Text String is text and can be a single character or a series of characters enclosed in quotation ("") marks.
In the function declarations below, the parameter name Value means any type of numeric value, text or a cell reference.
Function Parameter Delimiter
The delimiter to use between parameters specified in Spreadsheet functions can either be a comma (,) or a semicolon (;). Example using comma delimiter: =SUM(1 , 2). Example using semicolon delimiter: =SUM(1,5 ; 10).
Which delimiter is used depends upon the Region setting in Global Settings >> Spreadsheet Settings. If the region you have set uses a comma (,) as a decimal point delimiter, then the Spreadsheet function parameter delimiter will be a semicolon (;). Keep this in mind when reviewing the functions below. The functions below use a comma (,) delimiter between parameters.
Defining a Range of Data
Some Spreadsheet functions can take a range of data as a parameter. This is specified when two cell references are separated by a colon (:). For these functions, the first cell reference (before the colon) specifies the upper lefthand corner of the range and the second cell reference (after the colon) specifies the lower righthand corner of the range. This conceptual rectangle must always be drawn from upper left to lower right. As such, the row number specified by the second cell reference must always be equal to or greater than the row number specified by the first cell reference.
Specifying a range of data within a single column is well understood, as the range is easily viewable and creates a single column of data. It is, however, still necessary that the row values are increasing. For example, specifying the range B3:B5 is valid, but B5:B3 is not and will give a #REF error.
It is also possible to specify a range of data that crosses between columns. When doing this, the data that is contained with the rectangle formed from the first cell reference to the second cell reference is the range of data that will be used. For example, specifying a range of B3:C5 will include the data in the following cells: B3, B4, B5, C3, C4, and C5. As noted above, giving a range of values where the row number of the second cell reference is less than the row of the first cell reference will result in a #REF error.
Serial DateTime Values
Sierra Chart Spreadsheets store Dates and Times as double precision floating point numbers which represent the time since 1899Dec30 at 00:00:00. This datetime is not in any particular time zone. It can represent any time zone. To set the time zone, refer to Time Zone.
The integer part of the floatingpoint number represents the days and the fractional part, to the right of the decimal place, represents the time. This is exactly the same way as Excel and OpenOffice Calc represent date and Time values. This is called a Serial Date Time value.
Note that due to historical issues Excel does have a mistake in that it includes February 29, 1900, which did not exist. Therefore, Excel has 18991231 as day 0 and there will be a 1 day discrepancy between Sierra Chart and Excel for dates prior to March 1, 1900.
The Spreadsheet Study, Spreadsheet System/Alert and the Spreadsheet System for Trading studies output DateTime values to column A using this format.
Time Examples: 12 PM would be represented as .5. 1 minute or 00:01:00 would be represented as 1.0/1440.0. There are 1440 minutes in a day.
00:01:10 would be represented as 70.0/86400.0. There are 86,400 seconds in a day. 1 second evaluates to 1.15740740E5.
Date Examples: 1900Jan2 would be represented as 3.
Comparing Serial DateTime Values
Since DateTime values are stored as floatingpoint numbers, they are imprecise when you are performing comparisons to them. Two DateTime values that are the same when they are formatted as a Date and Time string, may not give you an exact comparison due to floating point error. You can see the exact values if you format the spreadsheet cell containing the DateTime value to a number with 9 decimal places.
A solution when doing an equals comparison between 2 DateTime values between two different sheets in the Spreadsheet, is to use a formula similar to the following: =ROUND(A3,8)=ROUND(Sheet2!A3,8) .
Sierra Chart internally stores DateTime values in the same way as Spreadsheets do. For further information, refer to the SCDateTime data type page.
Any of the available Spreadsheet Functions which accept a Serial DateTime Value parameter or return a Serial DateTime Value can be used when working with DateTime values in a Spreadsheet.
Using the Equivalent of COUNTIF, AVERAGEIF, MAXIF, MINIF, SUMIF
The Spreadsheets in Sierra Chart do not support the following functions: COUNTIF, AVERAGEIF, MAXIF, MINIF, SUMIF.
These are not supported due to the complexity of supporting criteria text. However, there is an alternative method to effectively perform these functions.
The Spreadsheet Studies support up to 60 formula columns. It is possible to use additional formula columns with the basic supported Spreadsheet functions to accomplish the same result as these unsupported functions.
The formula =COUNTIF(AA3:AA12,">50") can be implemented in the Sierra Chart Spreadsheets as follows:
In one of the available Spreadsheet formula columns, by default K through Z, enter this formula: =IF(AA3>50,1,0). Assuming the prior formula was entered in formula column X, then enter =SUM(X3:X12) in another formula column. The result of this last formula will be the same as =COUNTIF(AA3:AA12,">50").

EDATE(Date, Months) (Link)  Returns the serial date that is the given number of Months after the specified Date. If Months is less than 0, the return value is the date that is the indicated number of months before the given Date. If the same day of the month does not exist in the resulting month, then the last day of the resulting month is returned. Returns #VALUE! if the arguments are not integers. 
EOMONTH(Date, Months) (Link)  Returns the serial date number of the last day of the month that is a number of months after the specified date. If the second argument is less than 0, the return value is the date that is the last day of the month the indicated number of months before the date.

The return value is 1based, meaning if the given SubString is found at the very beginning of the given FullString, the return value will be 1. By default, FIND begins the search for the given SubString at the beginning of the given FullString, but this can be moved by specifying a value greater than 1 for the optional StartPosition parameter. The search is casesensitive (use SEARCH for a caseinsensitive search). Returns 1 if the given SubString is empty. Returns #VALUE! if no match is found, or the given StartPosition is beyond the length of the given FullString, or one of the strings is not a text value, or the given StartPosition is not an integer value.

GetCorrespondingMatch(SearchColumn, SearchValue, NearestOrExact, SearchRangeOrderingFlag, SameValueResolution, ReturnResultColumn, ReturnResultRowOffset) (Link)  Searches a range of values for the SearchValue and returns a reference to the corresponding cell at the same found row index, or an offset, in another column range. SearchColumn: The column range to be searched. SearchValue: The value to search for in the SearchColumn. Only doubles, integers and TRUE/FALSE are supported. Specifying a text value returns an error. Searching for text is not supported. Any value given for SearchValue that cannot be interpreted as a double, integer or TRUE/FALSE value results in a #VALUE! error. NearestOrExact: 0 = exact match. 1 = nearest match. SearchRangeOrderingFlag: 1 = SearchColumn values are ascending. (Lowest numbered row has the lowest numbers. Highest numbered row has higher numbers).
SameValueResolution: When there are values which repeat within an ordered SearchColumn, this parameter indicates how to resolve that. 1 = Use higher numbered row index. 0 = Use lower numbered row index. ReturnResultColumn: The column range where a reference will be returned for the corresponding row where the match was found. This parameter can be the same as SearchColumn. ReturnResultRowOffset: A positive or negative row offset for the row returned by ReturnResultColumn. 
HLOOKUP(Value, Range, RowInRange, [ApproximateMatch]) (Link)  Searches for the given Value in the topmost row of the given Range, and returns a reference the the cell at the same column of the found value, at the row at the given RowInRange.
RowInRange is a row index within the given Range, where 1 is the topmost row of the given Range. If ApproximateMatch is given as TRUE, and no exact match is found, the last value within the given Range that is less than the given Value will be used. When ApproximateMatch is given as TRUE, the values in the topmost row of the given Range are assumed to be in ascending order. If ApproximateMatch is not given or given as FALSE and the given Value is not found, #N/A! is returned. Returns #VALUE! if the given Value cannot be resolved to an actual value (such as if a range reference is given), or the given RowInRange cannot be interpreted as an integer value, or the given ApproximateMatch cannot be interpreted as a boolean value. Returns #REF! if the given Range is not valid, or the given RowInRange is beyond the number of rows in the given Range. Returns #NUM! if the given RowInRange is less than 1. 
HOUR(Serial DateTime Value) (Link)  Returns the hour for the given Serial DateTime Value. This function will return values in the range 023. Returns #VALUE! if the given DateTime cannot be interpreted as a serial datetime value. 
HULL_INTERMEDIATE(Reference, Value) (Link)  Returns the Intermediate calculation values for the Hull Moving Average. This is meant to be used in combination with the HULL_RESULT function, with this function in one column and the HULL_RESULT function in another column. The Reference is to the first (top) cell of the data and the Value defines the length of the Moving Average (the number of cells to include). The Value used in this function needs to match the value used in the HULL_RESULT function. Empty cells are considered to have a value of 0. Returns #VALUE if the first parameter is not a reference to a cell, or if the second parameter is not an integer, or if any of the values within the input range is not a number. Returns #NUM if the Value parameter is not large enough for a complete calculation. 
HULL_RESULT(Reference, Value) (Link)  Returns the final calculation values for the Hull Moving Average. This is meant to be used in combination with the HULL_INTERMEDIATE function, with this function in one column and the HULL_INTERMEDIATE function in another column. The Reference is to the first (top) cell of the HULL_INTERMEDIATE column and the Value defines the length of the Moving Average (the number of cells to include). The Value used in this function needs to match the value used in the HULL_INTERMEDIATE function. Empty cells are considered to have a value of 0. Returns #VALUE if the first parameter is not a reference to a cell, or if the second parameter is not an integer, or if any of the values within the input range is not a number. Returns #NUM if the Value parameter is not large enough for a complete calculation. 
IF(Condition, TrueValue, FalseValue) (Link)  Returns the value of TrueValue if the given Condition is equal to TRUE. Returns the value of FalseValue if the given Condition is equal to FALSE. Returns #VALUE! if the condition could not be interpreted as a boolean value.
Multiple IF statements can be strung together to create a series of IF/ELSE IF functions. To do this, simply put additional IF statements for the FalseValue arguments. For example: IF(A > B, 1, IF(B > C, 2, 0)). This would evaluate as: if A is greater than B then 1, else if B is greater than C then 2, else 0. 
INDEX(Range, Index) or INDEX(Range, Row, Column) (Link)  Returns a cell reference within the given Range, either at the given Index or the given Row and Column within the Range. If using Index (only one parameter after Range) on a Range with multiple rows and columns, the items are ordered down by rows first, and then across by columns.
Index, Row, and Column are all 1based, meaning using a value of 1 will return the first value. Returns #REF! if the given Index, Row, or Column is outside of the given Range. Returns #VALUE! if the given Range is not a cell reference range type, or if the given Index, Row, or Column could not be interpreted as integer values. 
INDIRECT(ReferenceText) (Link)  Returns a reference specified by the given ReferenceText. The ReferenceText must be a text value that can be parsed as a standard reference as used in formulas. This function only supports basic cell references, basic cell range references, and basic column range references; advanced references are not supported. Returns a #REF! error if the given ReferenceText cannot be parsed or is otherwise invalid. Returns #VALUE! if the given ReferenceText is not a text value.
An example ReferenceText is "E3". ReferenceText can be created by a formula. For example, if cell H5 contains the number 3, then the following formula will return E3: CONCATENATE("E", H5). 
INT(Number) (Link)  Rounds the given Number down to the next whole integer. Returns #VALUE! if the given Number is not a number. Returns 0 if Number is an empty value, like a reference to a cell that contains no data.

ISSAMETIMETOHOUR(DateTime1, DateTime2) (Link)  Returns TRUE if the time values for both of the given serial datetime values are at the same time, down to the hour. Example: comparing 12:00:00.000 to 12:59:59.999 would return TRUE, but comparing 12:59:59.999 to 13:00:00.000 would return FALSE. The date component of both values is ignored. Returns #VALUE! if either of the given values cannot be interpreted as a serial datetime value. 
ISSAMETIMETOMILLISECOND(DateTime1, DateTime2) (Link)  Returns TRUE if the time values for both of the given serial datetime values are at the same time, down to the millisecond. Example: comparing 12:00:00.000 to 12:00:00.000 would return TRUE, but comparing 12:00:00.000 to 12:00:00.001 would return FALSE. The date component of both values is ignored.

Example: comparing 12:00:00.000 to 12:00:00.999 would return TRUE, but comparing 12:00:00.999 to 12:00:01.000 would return FALSE. The date component of both values is ignored. Returns #VALUE! if either of the given values cannot be interpreted as a serial datetime value. 
ISTEXT(Value) (Link)  Returns TRUE if the given Value is a text value type. Otherwise returns FALSE. 
LARGE(Numbers, NthLargest) (Link)  Returns the Nth largest number from an array of numbers. The first argument is the array, while the last argument controls which number will be returned. 1 means the largest number, 2 the second largest and so on.
Empty cells are not counted, TRUE will be considered as 1, FALSE as 0. Returns #VALUE! if the last argument is larger than 1 or greater than the number of numerical values (and booleans) in the array. 
LEN(Text) (Link)  Returns the number of characters in the given Text string. Returns #VALUE! if Text is not a string. 
LEFT(Text, Count) (Link)  Returns the given Count number of characters from left side of the given Text string. If Count is greater than the length of the given Text string, then the entire string will be returned. If Count is 0, an empty string is returned.

TEXT(Value, Format) (Link)  Returns the given Value as a text value. The given Format text is used for formatting numeric values. It is optional and has no effect on other value types.
To format a number with a specific number of decimal places, use a format such as ".000" or ".###". For each "0" following the decimal point in the Format, that many decimal points will be displayed, even if they are insignificant. For example: TEXT(0.05, "0.000") will return "0.050". For each number sign (#) following the decimal point in the Format, that many decimal points will be displayed, except for trailing zeros. For example: TEXT(0.05, "0.###") will return "0.05". These two methods can be combined such that ".00##" will format numbers with a minimum of two decimal digits and a maximum of four decimal digits. Values will be rounded to the maximum number of decimal digits that can be shown. Zeros placed before the decimal point indicate to use leading zeros for the whole number. For example: TEXT(2.5, "000.##") will return "002.5". Number signs (#) before the decimal point have no effect. The decimal point in the Format text must match the global setting that specifies the decimal point character. The decimal point character used in the returned value will match the global setting.
