Click here for the Optuma Scripting forum page to post / view questions on creating specific formulas and scripts.General Interface
The following is the interface that displays when selecting the Script Manager in Optuma (located under the Settings menu).When the Script Manager is accessed it is ready for you to add a new custom formula, you just need to enter a name for the script and then type the formula in the window beneath the Script Name. When complete leftclick the Update Button.
Optuma includes a list of preprogrammed scripts/formulas that you can use. These are listed in the lefthand pane of the Script Manager under Default Scripts. You can search for any default or created scripts by just typing the name of the script you are looking for in the Type to search field.
Formula Interface
The interface for using formulas is extremely userfriendly:
As soon as you start typing in a formula field, you will see a list of functions or operations that are available for you to enter. The more letters you type, the more the list is reduced to only show items that match what you are typing.
Formula Breakdown
A formula you create can contain any or all of the following parts:
Functions: A function, such as MA(), represents an existing calculation or indicator (in this case a Moving Average) and you can enter adjustments for the function within its parentheses. Each function has a specific adjustment syntax.
Constants: You can also enter constants, such as numbers, directly into a formula.
Operators: Operators are the symbols that are used to specify the type of calculation that you want the formula to perform. For example, the * (asterisk) operator multiplies numbers.
Colour Coded Lines
In the Script Manager there are some colours used to highlight various items.
 Comment Lines will be displayed in Green text.
 When working between two parentheses the starting ( and the closeing ) will be highlighted in Blue.
 When setting up variables, if there is a naming conflict (already in use for example) the text will display in Red.
Function Adjustments
Each function available in Optuma has a number of properties that can be adjusted (number of bars used to calculate a Moving Average, for example).
Rather than having to commit the syntax to memory, Optuma simplifies this process by providing you with a properties panel identical to the one available in the Control panel.
Once a function is added to the formula, leftclick on the empty parentheses and the properties panel will display:
As you made adjustments in the panel, the formula will be updated automatically to include the function adjustments.
Script Caching
In Optuma v1.3 a new caching system was introduced into Optuma Scripts to improve performance and reduce resource load when using scripts that refer to an offset / previous value. Scripts using the SELF() or VARIABLE[1] functions will now run much faster in Optuma v1.3 and require less memory / CPU processing power.
Function List
The following table contains a list of all the functions available in the Optuma formula language. If no adjustments are made within the functions parentheses, Optuma will use the default settings saved for that indicator.
Function  Name  Description 

ABS  Absolute Value  Ensures the value output of the script is a positive number. 
ACC  Accumulate  Combines the values over a selected period (similar to SUM). 
ACCB  Acceleration Bands  Acceleration Bands were created by Price Headley and are mentioned in his book Big Trends in Trading. Acceleration Bands use a period of 20 bars by default, to create an envelope of 2 lines. 
ACCSINCESIGNAL  Accumulate Since Signal  Takes two scripts, the first script is the one that is accumulated and the second is a Boolean script that signals a reset of the accumulation. 
ACTIVEWEIGHT  Active Weight  Makes reference to the active weight (requires Bloomberg data). 
ADX  Average Directional Movement Index  The Average Directional Movement Index is an indicator designed to measure the strength and direction of a trend. The indicator consists of three components: the plus directional indicator (+DI), minus directional indicator (DI) and the Average Directional indicator.

ARCCOS  ArcCos  The arccosine of x is defined as the inverse cosine function of x when 1≤x≤1. 
ARCSIN  ArcSin  The arcsine of x is defined as the inverse sine function of x when 1≤x≤1. 
ARCTAN  ArcTan  The arctangent of x is defined as the inverse tangent function of x when x is real (x∈ℝ). 
AROON  Aroon  The Aroon indicator was created by Tushar Chande in 1995. The Aroon up and the Aroon down fluctuates between 0 and 100. Values close to 100 represent a strong trend, Values close to 0 represent a weak trend. The lower the Aroon up, the weaker the uptrend, and the stronger the downtrend, and vice versa. 
AROONOSC  Aroon Oscillator  The Aroon Oscillator was created by Tushar Chande. This indicator is designed to display the difference between the two lines which make up the Aroon indicator (Aroon Up and Aroon Down). This is done in an effort to both highlight and measure the strength of a new trend. 
ARR  Annual Rate of Return  Use to calculate the annual rate of return over a userdefined period. 
ASPECTS  Aspects  Used with the PVAL() function to allow the search of vairious aspects (Conjunction, Sextile, Square, etc) between two or more planets. 
ATR  Average True Range  Average True Range Stop Loss calculation compares the price range for today with the highs and lows of the previous day. The highest of these values (the largest range) is selected as the true average range for the period. This figure is calculated each day. 
ATRTSCAN  ATR Trailing Stop Scan  Average True Range Stop Loss calculation compares the price range for today with the highs and lows of the previous day. The highest of these values (the largest range) is selected as the true average range for the period. This figure is calculated each day. 
AUTOCORR  Auto Correlation  Auto correlation (also referred to as crossautocorrelation or serial correlation) is the correlation of a chart with itself at different points in time designed to highlight repeating patterns within a chart. 
AVBT  Average Volume By Time  This indicator shows the current day''s volume bars compared to the same bars over a userdefined period. Here''s an example of a 15 minute chart of Microsoft. The shaded area below the current day is the average volume over the past 2 weeks. The red bars indicate where the volume is above the average for that 15 minute period. (Requires Intraday Data) 
BARCOUNT [NEW]  BarCount  Use this in a Show Plot to calculate an average of all bars being loaded.

BBW  Bollinger Bandwidth  The Bollinger Bandwidth gives an indication of how wide the Bollinger Bands are as a function of the middle band. Used to identify the squeeze at low values and the end of trends at high values. 
BETA  Beta  The Beta Coefficient tool is used to compare the volatility of the selected stock with that of the entire market (usually an Index such as the XJO or Dow). 
BPB  Bollinger Percent B  The Bollinger %B tool is similar to the Stochastic tool, however the range is calculated from the Bollinger Bands rather than actual price. Whereas Stochastics will always oscillate in a range between zero and 100 since price can never penetrate above the price range (else it will increase the price range itself), price does penetrate the Bollinger Bands frequently. Thus Bollinger %B can move above 100 and below zero, this merely indicating that the close is outside of the bands. 
BREADTHDATA  Breadth Data  The Breadth tool requires access to the Bloomberg Terminal. When applied to an equity the Breadth data for the parent index is used automatically. For example, a US Equity will display the S&P500 Advance Decline Breadth values.

CLU  Time Clusters  A number of tools in Optuma, (Fibonacci, Gann, Astronomical, etc) are designed to locate important dates on a chart. When multiple tools are applied to a chart it can be difficult finding important convergences of these tools, which can assist in highlighting important turning dates in the market. The cluster tool has been designed with this problem in mind, and resolves the issue by highlighting vertical tool convergences in a simple, uncluttered manner. 
COI  Coppock Indicator  The indicator is named after Edwin Coppock. Coppock thought setbacks in the stock market were like bereavements and required a period of mourning before normal spirits revived. So he asked the church leaders of the day how long it took people to get over the death of a loved one. The answer was between 11 and 14 months. From this Coppock developed a series of calculations designed to signal when stock market mourning would be over. 
CORREL  Pearson's Correlatin Coefficient  The Pearsons Correlation Coefficient indicator represents the relationship between the selected stock and a comparison code (Dow or XJO for example) using variables that are measured on the same interval or ratio scale. 
COS  Cosine  The trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a rightangled triangle) to the hypotenuse.

FIRST  First Value  Returns only the first value of a script function or criteria. For example First(MA()) will return the first Moving Average value for the code(s). 
FLD  Hurst Future Line of Demarcation  The FLD is probably the most important tool in all cycle analysis, according to Hurst. It's many uses include: Location of wave troughs and crests during phasing analysis, Determination of price objectives, Assessment of trend by comparison of pasttime price objectives with actual price movement, Pricemovement forecasts by means of FLD pattern analysis and Action signals. The FLD is constructed by shifting the centered moving average by half the length of the moving average. Half the cycle will before final data price on the chart and half after. When price intersects a Single FLD, Hurst would consider that at that point, Price was half way through the cycle (that is the cycle of length defined in the FLD).

This information is sourced from Bloomberg and requires a connection to Bloomberg Terminal. 
FOURIER  Fourier Wave  In Signal Processing, Fourier analysis is used as a way to break up complex waves (cycles) into discrete sinusoidal components. The process uses the Fast Fourier Transform to examine the closing prices of the data and determine the cycles that have the highest correlation to the cycles in the data. 
FT  Fisher Transform  The Fisher Transform indicator is an oscillator based on complex mathematical theories (such as probability density functions) and transforms prices into sine wave that seeks to pinpoint extremes in the market. The tools is made up of pair of lines moving above and below the central value of zero. One line is the current Fisher Transform value and the other, the trigger line. A signal, bullish or bearish, is generated when the Fisher Line crosses above or below the trigger line and/or when the indicator reaches bullish or bearish extremes.

HPI  Herrick Payoff Index  Developed by John Herrick, the Herrick Payoff Index is designed to show the amount of money flowing into (or out of) a futures contract. A value above zero represents money flowing in (bullish), below zero money flowing out (bearish). It is important to note that this indicator makes reference to Open Interest data, so the chart you apply this to must have OI values. 
HPP  Highest Price Period  Highest Price Period uses the highest high over a user selected period (240 bars by default), and finds the bars where its current high is greater than the highest high. 
HTB  Home Trader Band  Home Trader Bands are based on a standard Moving Average. The actual band lines are offset by a positive and negative ATR value from the central moving average value, to provide upper and lower bands. 
HTBE  Home Trader Band Extension  Home Trader Band Extensions are based on Home Trader Bands. It is horizontally offset by 1 from Home Trader Bands.

IMPULSERIPPLES  Impulse Ripples  The Impulse Ripples tool uses a proprietary Optuma algorithm to identufy dates where a potential changes in trend may occur. The Impulse Ripple tool is typically applied to a significant pivot high or low point on the chart. 
INDEX  Index  Allows you to display data for the underlying codes primary index. For example ASX Codes will use XJO (Top 200), US Equity codes will use SPX (S&P500). 
INERTIA  Inertia Indicator  The Inertia Indicator is a smoothed version of the RVI indicator and attempts to extrapolate the prevailing price trend. The smoothing effect is calculated with a combination of Exponential Moving Average and Linear Regression. When this indicator is above 50%, an increasing price trend is indicated. When the indicator falls below 50%, a decreasing price trend is indicated. 
INV  Inverse  Allows you to take the underlying value or plot of a script and inverse it (should not be confused with Invert which is a different process). 
INVMA  Hurst Inverse Moving Average  The Inverse Moving Average was a tool that Hurst used to assist him in determining the dominant cycles on the chart. In a complex market it can be difficult the spot the cycles, this tool helps with that. Hurst often referred to this as an "Inverse HalfSpan Average" 
ISMEMBER  Is Member  Will show a true results when the underlying chart is a member of the selected index (S&P500 for example) and a false result when it is not a member. Requires Optuma Symbol Lists. 
ISTICKER  Is Ticker  Returns whether the source is the same code as the passed in. This can be used to match a single code when scanning a list of codes. 
JDKRS  RRG Lines  The RRG Lines tool is a proprietary tool, based on the work of Julius de Kempenaer. 
KAGISWING  Kagi Swing  Kagi charts are believed to have been created around the 1870's in Japan. Kagi charts, as with Gann Swing charts, display rising and falling vertical lines to indicate price action while ignoring the time element. The lines created by Kagi charts are usually displayed as thick or thin depending on price action, direction and the point at which prices penetrate a previous high or low. Optuma, however, distinguishes between the thick and thin lines using colour. Blue represents thick lines and Green represents thin lines. 
KC  Keltner Channel  Keltner Channels are based on a standard Moving Average. The actual band lines are offset by a positive and negative standard deviation value from the central moving average value, to provide upper and lower bands.

LOWESTLOW  Lowest Low  Allows you to search for the Lowest value over x periods. You can define the look back period, or set it to All Time. This can be done on charts, or indicator values. 
LOWESTSINCE  Lowest Low Since Signal  Allows you to search for the Lowest value over x periods but only after a specific criteria has first been met. For example, a Moving Averages lowest value in the last 30 days, after the Close price crossed below the MA line. 
LPP  Lowest Price Period  Lowest Price Period uses the lowest low over a user selected period (240 bars by default), and finds the bars where its current low is less than the lowest low.
