Syntax

Public function TradeVolumeIndex(ByRef Data As Database, ByRef Source As Field, ByVal Volume As Field, ByVal MinTickValue As Double, Optional ByVal FieldAliasName As String = "") As RecordSet

 Overview

The Neural Indicator uses a neural network (an advanced form of artificial intelligence) to analyze non-linearity that may be hidden in technical indicators.

Interpretation

The Neural Indicator output most closely resembles an oscillator. Values may have a wide range and are seldom the same for each run through the neural network (due to random initialization) unless a very strong relationship between future price and the indicator being analyzed exists, or the network has been overtrained.

Note

The NeuralNetwork class is different from other TA classes. This is not a standard technical indicator, but rather an advanced form of artificial intelligence. The NeuralIndicator function may take several minutes to complete, depending on argument values. LearningRate is a double value specifying the neural network learning rate (0.1 to 1+), Epochs is a long value specifying the amount of neural network learning to perform (1 to 32,000 – 500 or less is recommended), and PercentTrain is a double value specifying the amount of data to be used as an out-of-sample neural network training set.
