Formula Functions & General Interface

Overview

Optuma brings you one of the easiest to use formula languages ever seen in trading platforms. Many of the modules in Optuma use this language (such as the Back Tester and Scanning Manager) providing you with a level of customisation previously unavailable.

The following tools and modules can be used with custom formulas:

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 left-click the Update Button.

Optuma includes a list of pre-programmed scripts/formulas that you can use. These are listed in the left-hand 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 user-friendly:

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, left-click 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.

More Information

Each script function includes a More Information link you can click. This will automatically take you to a Knowledge base article that covers the script, or the underlying tool the function represents in more detail.

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.
ADL	Accumulation/ Distribution	Accumulation Distribution displays the interaction between price and volume and is used to detect divergences between volume and price actions. Accumulation Distribution is an evolution of On Balance Volume, comparing opening and closing prices to the trading range for a set period, with the result used to weight the volume.
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.
ALPHA	Alpha	Alpha (a common measurement of investment performance and risk), compares the return of a security compared to an index or benchmark. A negative Alpha value would mean the security under-performed compared to the benchmark.
AMA	Adaptive Moving Average	Developed by Perry Kaufman the Adaptive Moving Average is a single average which dynamically varies its own length, typically from a 2-period to a 30-period average, according to the degree of volatility and directionality in the market.
ANR	Angle Returns	This indicator is based on the concept that angles which occur at a major turning point in the market will continue to have an influence. The Angle Returns tool reviews all the angles of the selected planets at the time of the selected turning point and searches for those same angles in the chart's entire range (forwards and backwards from the selected point).
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 user-defined period.
ASPECTS	Aspects	Used with the PVAL() function to allow the search of various aspects (Conjunction, Sextile, Square, etc) between two or more planets. Requires the Astro tools.
ASR	Aspect Returns	This indicator is based on the concept that aspects which occur at the point of a major change in trend will continue to influence the market. The Aspect Returns will highlight all the aspects between the selected planets for the date and time of the selected Low / High and searches for those same aspects in the chart's entire range (forwards and backwards from the selected point).
ATR	Average True Range	Average True Range is a measure of volatility. Introduced by Welles Wilder, he found that high Average True Range values often occur following a market sell off or "panic".
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 cross-auto correlation 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 user-defined 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.
AVWAP	Anchored VWAP	The Anchored Volume-Weighted Average Price indicator was developed by Brian Shannon at Alphatrends.net. The Anchored VWAP is applied to a specific bar, and from that point calculates the cumulative value and volume to determine the weighted-average price. These levels can be used to determine important support and resistance levels.
BARCOUNT	BarCount	Use this in a Show Plot to calculate an average of all bars being loaded.
BARDATE	BarDate	This function takes the date of a bar and converts it into an integer. For example 19-06-2017 = 42902
BARINDEX	BarIndex	Coming Soon
BARROMCONTRATREND	BarroM Contratrend Scan	A scan based on the methods of Ray Barros which look for specific movements on the Midos SI and Value Chart indicators.
BARROSAVGVOL	Barros Swing Average Volumes	The Barros Swing Average Volume tool, provides an average value for volume of bars contained within an initial, mid or final Barros Swing.

BBOA	Bollinger Break Out Above Data List	Allows you to perform a scan using the Bollinger Break Out Above criteria devised by John Bollinger.
BBOB	Bollinger Break Out Below Data List	Allows you to perform a scan using the Bollinger Break Out Below criteria devised by John Bollinger.
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 Stochastic's 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	When applied to an equity the Breadth data for the parent index is used automatically. For example, a US Equity will display the S&P 500 Advance Decline Breadth values. Requires the Optuma Breadth Measures data group or a Bloomberg Connection.

CHANGESINCESIGNAL	Change Since Signal	Displays the change in price (value or percentage) since a triggered signal.
CHARTPATTERN	Chart Pattern	Allows you to search for a specific chart patterns such has AB=CD, etc.
CHOPPINESSINDEX	Choppiness Index	The Choppiness index was created by Bill Dreiss and is used as a measure of the current state of a stocks trend. There are lines placed on the Fib levels of 31.8 and 61.8. Choppiness Index values below the 31.8 generally indicate a trending market, where as those above 61.8 indicate a choppy market.
CHST	Chandelier Stop	The Chandelier Stop was developed by Charles Le Beau and plots a trailing stop loss calculated from Average True Range. The stop can be used on both bull and bear markets with the Chandelier line plotting above the price in a downtrend and below the price on an uptrend.
CI	Composite Index	The Composite Index is a proprietary tool, developed by Constance Brown from Aerodynamic Investments Inc. For more information, please visit https://aeroinvest.com/
CIDX	Congestion Index	Congestion Index is the ratio of the price change to the range change between highest price and the lowest price for a specific period (default 20 bars). The result is then smoothed to produce the final value.
CLOSE	Close	The close function returns the closing value of each bar of the source data
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.
CMF	Chaikin Money Flow	Chaikin Money Flow, developed by Marc Chaikin, measures buying and selling pressure (Money Flow Volume) over a set period of time (21 days by default) oscillating between a value of 1 and -1.
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 Correlation Coefficient	The Pearson's 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 right-angled triangle) to the hypotenuse.
COSC	Chaikin Oscillator	The Chaikin Oscillator was created by Marc Chaikin, and is used to measure the momentum of the AD Line using MACD. The value of the Oscillator is the variation between the 3 day EMA of the AD Line and the 10 day EMA of the AD Line.

DOMENV	Hurst Dominancy Envelope	The Dominance Envelope is a pair of smooth zones bounding the upper and lower edges of the relatively long undulations in the price movement. This envelope encloses most of the price bars within a constant height channel. It contains within it the wave movements in the price action that are most visually evident. Requires the Hurst Module.
DONCH	Donchian Channel	Donchian channels were developed by Richard Donchian. The two outer bands are plotted as the highest high and lowest low for a set period with the central band calculated as the average of the two.
DRAWDOWNSTOP	Drawdown Trailing Stop Loss	Alan Hull's Drawdown Trailing Stop tool trails behind the most recent highest closing price by a given percentage (20% by default). Every time a rising trend makes a higher closing price then the drawdown stop loss will increase to maintain the 20% buffer. The trailing stop is prevented from going lower when the price activity falls, but once the stop loss has been breached for several consecutive number of bars (10 by default) then it will reset to the drawdown percentage below the closing price of the 10th bar.
DROSC	Derivative Oscillator	The Derivative Oscillator is a proprietary tool, based on the work of Constance Brown from Aerodynamic Investments Inc. For more information, please visit https://aeroinvest.com/
DTB	DGL Trade Bands	DGL Trade Bands are entry/exit trade bands. There are two bands for buying and two for selling. Buy 1 and Buy 2 bands are used to determine possible entry points.

It's many uses include: Location of wave troughs and crests during phasing analysis, Determination of price objectives, Assessment of trend by comparison of past-timeprice objectives with actual price movement, Price movement 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 be before the 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). Requires the Hurst Module.
FLOOR	Floor	The Floor function is used to round down.
FLVSCAN	Fixed Volatility Stop Scan	Allows you to scan for bars crossing the Fixed Volatility Stop line (Back Tester only).
FO	Forecast Oscillator	The Forecast Oscillator compares the actual price to the Time Series Forecast and calculates a percentage between -100% and +100%.

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.
FSVSCAN	Fixed Short Volatility Stop Scan	Allows you to scan for bars crossing the Fixed Short Volatility Stop line (Back Tester only).
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.

It is made up of two groups of exponential moving averages and is used to understand the strength and nature of the trend. The short-term group are 3, 5, 8, 10, 12 and 15 day exponential moving averages. The long-term group is made up of 30, 35, 40, 45, 50 and 60 day exponential moving averages.
GMP	Gann Mass Pressure	W.D. Gann's Mass Pressure is a selective or incomplete Decennial Pattern: Each value of this composite is derived from 6 past price values of the DJIA exactly 80, 60, 40, 30, 20 and 10 years back. Gann Mass Pressure and the Decennial Pattern often times look very much the same, and have identical turning-points. Requires the Gann tools.

HAP	Hathaway Average Price	The Hathaway Average Price tool is a proprietary indicator available with the Hathaway Tools add-on from Pattern to Profit. The tool takes the average closing prices from a designated starting point, which accumulates over time, as opposed to a simple moving average which averages the closing prices over a designated fixed period of time. Requires the Hathaway Module.
HARTSWING	Hart Swing	The Hart Swing is a trend indicator and can be used much like Gann Swings. The tool was developed by Joseph Hart of Trend Dynamics. Through the use of a series of time filters, the tool segregates price action into encompassable components, and in doing so filters out the noise of other time frames.
HBS	Hundred Base	Similar to the Relative Index Comparison tool however the Hundred base indicator differs by not dividing the source by an index. Instead the indicator sets a starting date and bases the value at 100 from that date (e.g. Left Screen Edge).
HBT	Hilbert Transform	The Hilbert Transform indicator is a linear operator, based on the separation of the cycle phase into two components, the Quadrature and InPhase and is designed to locate relative peaks and troughs on the chart.
HIDDEN	Hidden	The Hidden() function - in conjunction with an IF() statement - allows you to hide a plot until certain criteria are met.
HIGH	High	The high function returns the highest value of each bar of the source data.
HIGHERTIME	Higher Time Moving Average	The Higher Time Moving Average is a Moving Average that is drawn based on a different time period. For example, you can apply a weekly moving average to a daily time period chart.
HIGHESTHIGH	HIghest High	Allows you to search for the Highest 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.
HIGHESTSINCE	Highest High Since Signal	Allows you to search for the Highest value over x periods but only after a specific criteria has first been met. For example, a Moving Averages highest value in the last 30 days, after the Close price crossed above the MA line.
HLTR	Helion Transits	The Helion transits tool will plot the times that selected planets are at Aphelion and Perihelion during their orbit. Requires the Astro tools.
HMA	Hull Moving Average	A moving average (weighted) based on Allan Hulls published calculations. For more information, please visit Alan's website - http://www.alanhull.com/
HMMA	Hull Multiple Moving Average	The Hull Multiple Moving Average is a tool developed by Author and trader Alan Hull. HMA uses two groups of Moving average lines to track and filter price movements. For more information, please visit Alan's website - http://www.alanhull.com/
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.
HV	Historical Volatility	A measure of the price changes of a security over a specific period of time. Defined as the standard deviation of the continuously compounded returns on the security.
HVB	Historical Volatility Bands	Taking the Historical Volatility value and added positive and negative delta to it forms these bands that rise and fall based on the volatility of the security.
ICHIMOKUCLOUD	Ichimoku Cloud	The Ichimoku Cloud indicator was developed before World War II by a Tokyo newspaper writer. It is designed to display support and resistance levels, trend direction, and entry/exit points.
IF	If	Allows a script to produce multiple results based on which criteria is being met. For example, If the Close is Higher than a MA the script result is 1 otherwise it is zero.
IMPULSERIPPLES	Impulse Ripples	The Impulse Ripples tool uses a proprietary Optuma algorithm to identify 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&P 500).
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 to spot the cycles, this tool helps with that. Hurst often referred to this as an "Inverse HalfSpan Average". Requires the Hurst Module.
ISMEMBER	Is Member	Will show a true results when the underlying chart is a member of the selected index (S&P 500 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.
JDKFOREX	JDK Forex	Allows you to reference the RRG calculations specific to Foreign Exchange data. Requires at least a Professional services subscription or the RRG Module.
JDKRS	RRG Lines	The RRG Lines tool is a proprietary tool, based on Relative Rotation Graphs by Julius de Kempenaer. Requires at least a Professional services subscription or the RRG Module.
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.
