FAQ
See Frequently Asked Questions.
Feedforward
An attribute of a neural network topology in which the values can bypass the processing in one or more hidden layers. Values that go through feedforward processing are combined with values that go through the hidden layers to produce a single value.
Field
One column of data in a data series. For example, the closing price of a stock is one field in the data series for that stock. Fields are used to hold data and calculate new values based on this data.
Field Delimiter
The character used to separate columns in a text file. Most text files are either comma-delimited or tab-delimited.
& For help with text files, see Importing Data into TradingSolutions.
Field Format
A set of formatting characteristics to use when displaying a field in the Spreadsheet View or the Portfolio View. Field formats are referred to by name and can be applied to one or more fields. For example, the Price format is used by default for High, Low, Open, and Close fields.
& For help with field formats, see Using Custom Field Formats.
Financial Indicator
A calculation based on the price and/or volume of a stock to determine a trend in those values.
Fitness (Genetic Algorithms Usage)
The evaluation of a potential set of values or settings during genetic optimization. Sets of values that produce better results than other sets of values are said to have a better fitness.
& For help with optimization, see Optimizing Signals and Predictions.
Fixed Width
A file format in which columns are assigned a fixed number of characters rather than being delimited by a character.
& For help with text files, see Importing Data into TradingSolutions.
Float
The number of shares outstanding for a common stock. Also, an abbreviation of floating point, which refers to a representation of numbers that allows for fractional amounts.
Focused Network
A type of time-lag recurrent network that has memory only in the input axon. An unfocused network also has memory in each hidden layer.
& For help with neural network topologies, see the Modify Field Dialog: Prediction Model page help.
Format
See Field Format.
Formula
The portion of a function definition that indicates how to process the inputs in order to produce an output. Formulas are also used when defining entry/exit system rules.
& For help with function definitions, see Calculating Values and Financial Indicators.
Four Digit Years
A specification that the year component of a date should include all four digits of the year, rather than just the last two digits.
Fractional Shares
Trading the ownership of incomplete shares, for example half and quarter shares. This is typically done to facilitate investing specific amounts of money. In actual trading, it is typically only available when trading mutual funds.
Frequently Asked Questions (FAQ)
A collection of common questions that arise about a given topic.
& For answers to frequently asked questions about TradingSolutions, see Answers to Common Questions.
Fully Recurrent Network
A recurrent neural network that does not include a non-recurrent feedforward processing path. Because of this, all data must flow through the recurrent processing.
& For help with neural network topologies, see the Modify Field Dialog: Prediction Model page help.
Function Definition
A series of mathematical calculations that take a set of inputs and produces a single output. A function definition is used when creating a calculated field. One function definition can be used in any number of fields and can also be used when creating new function definitions and entry/exit systems.
& For help with function definitions, see Calculating Values and Financial Indicators.
Function Group
A collection of function definitions. Groups are used to separate definitions during selection. Typically, the definitions in a group share common characteristics.
Fundamental Analysis
Analyzing securities by examining the earnings and assets of the underlying companies. This differs from Technical Analysis, which examines the trading of those securities.
