Error Adding Security, "Add or change would duplicate an existing security"

Last modified 08:56, 3 Jun 2015

Overview

Upon initiation of data distribution to a metastock database you may recieve an error message as below:

Error Adding Security, "Add or change would duplicate an existing security"

Symptoms

You will notice that the Metastock distribution does not complete all steps. Upon opening your security within your metastock viewer you notice that the data has not been updated.

Resolution

This error message most commonly appears when the metastock database file has entered a locked state.

This can happen if you have attempted to perform a read function on a file whilst it has opened for a write function.

First try closing down any software that would be accessing the metastock database and try to distribute data again.

If this does not work then it is possible that .LCK files have been created within the database structure.

Navigate to your Metastock database folder, within the Metastock folder run a windows search for any files in any of the subfolders contained within that have an .LCK extension.

If any are found then simply delete these files and attempt to run a distribution to your metastock database once more.
