Author: Optuma Team Last updated: Oct 5, 2023 14:35

## Functions Table

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.

## A - Functions

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??).
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.

## B - Functions

Function Name Description
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.
BARROSSWING Barros Swing The Barros Swing is a trend indicator and can be used much like Gann Swings. Trading methodology associated with the Barros Swings is accomplished through attending seminars hosted by Ray Barros. For further information on courses offered by Ray Barros, you can visit his website.
BARSTRUE Bars True Used in conjunction with a Boolean variable. Will output the total number of bars the boolean criteria has been true over a set lookback period (10 bars by default, but can be adjusted).
BARTYPES Bar Types Allows you to search for specific Bar Types in a script (e.g. Outside Bar, Inside Bar, Higher than Previous Day, etc).
BB Bollinger Bands Bollinger Bands 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.
BBII Bollinger II % Data List Allows you to perform a scan using the Bollinger II % criteria devised by John Bollinger.
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.

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.

Function Name Description
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.
KST Pring Know Sure Thing Know Sure Thing was developed by Martin Pring to show the overall momentum of a stock, or other financial asset. Traders typically use KST for trade signals or to confirm trends.

LRINT Linear Regression Intercept The Linear Regression Intercept tool calculates the line of best fit to the market price, using the least squares method, and is plotted on the chart in a way that is similar to a moving average. However, rather than being a simple averages calculation, the Linear Regression Intercept tool represents a statistically fitted line which reacts faster to changes in price when compared to a Moving Average.
LRSLOPE Linear Regression Slope The Linear Regression Slope tool calculates a slope value of theoretical regression lines involving the current bar and the previous (user selected) bars, with the final value of the slope being normalized and displayed as a histogram.
LRVAL Linear Regression Value The Linear Regression Value function calculates the correlation of the closing prices around the linear regression line. Based on the Trailing Linear Regression tool.
