Field Messages

ˇ Internal Error. Message

Messages that indicate "Internal Error" should not occur while using TradingSolutions.

Action: Please contact NeuroDimension for assistance, indicating any additional information in this message.

ˇ One or more input fields, trading style fields, or desired output fields cannot be processed because they contain errors (or their inputs contain errors).

This message appears when an input field or desired output field required for this field cannot be calculated, causing this field to not be available. It can also appear when the trading style used by this field references a field that contains an error.

Action: Examine any other messages for indications of which field may be encountering this error.

ˇ One or more input fields, trading style fields, or desired output fields cannot be processed because they no longer exist.

This message appears when an input field or desired output field required for this field has been deleted. It can also appear when the trading style used by this field references a field that has been deleted or was never created.

Action: Examine the input fields associated with this field, along with the trading style if applicable.

ˇ One or more input fields or desired output fields did not contain data.

All of the input fields and desired output fields for a date must contain values for that date to be used in the training set. This failure may be reported if a field is empty for the entire training range, or if percent change is being used and the value is zero for the entire training range.

Action: Check the values of the inputs and desired outputs of this field. For predictions, the inputs and desired outputs must be set for at least part of the training range.

ˇ The definition for this field contains an error.

This message appears when TradingSolutions cannot load this field to calculate this value.

Action: Double-click on this message to access the field definition and determine the source of the problem. If you cannot determine the cause of the problem, you may need to delete the field and recreate it.

ˇ The learning rates resulted in the cost evaluating to infinity.

Neural networks use internal weights to mathematically modify the input values to produce the output value. In some situations, it is possible for these weights to increase or decrease until a mathematical error is produced. Possible situations where this may occur are the step size or momentum being too high or the desired value being constant across the training set.

Action: This will typically not occur with the default settings. If you have adjusted the step sizes or momentum settings either directly or using genetic optimization, you may need to lower these values or re-optimize.

ˇ The neural network for this prediction could not be loaded.

This message appears when the neural network associated with a prediction cannot be loaded. It typically appears when a field uses a Custom Solution Wizard DLL and that DLL file has been renamed or deleted.

Action: Double-click on this message to access the field definition and examine the settings. If you cannot determine the cause of the problem, please contact NeuroDimension.

ˇ The selected network is recall only.

When using a Custom Solution Wizard DLL, the necessary components for learning must be included on the neural network breadboard. In addition, the Developers level of the Custom Solution Wizard must be used to generate DLLs for TradingSolutions.

Action: Replace the selected Custom Solution Wizard DLL with a DLL capable of learning.

ˇ The training samples could not be divided into exemplars based on the samples per exemplar setting.

When using a Custom Solution Wizard DLL with a dynamic network, the number of samples in the training set must be evenly divisible by the Samples/Exemplar setting of the breadboard. This setting can be found in the properties for the dynamic controller on your NeuroSolutions breadboard.

Action: Double-click on this message to access the field definition and determine the number of training samples that are being sent to the neural network from the Modify Field Dialog: Training Analysis page. Then, set the Samples/Exemplar setting on the NeuroSolutions breadboard appropriately and regenerate the DLL.

ˇ The training weights could not be saved.

When a neural model is trained for a prediction, the weights associated with that training are saved to a file. If the disk drive that holds your TradingSolutions work is full, these weights may not be able to be saved.

Action: Check the amount of space available on the disk drive containing your work directory, then try retraining the prediction.
