The Modify Data dialog allows you to correct data that is incorrect for any file that NeuroShell Trader is able to read. The folder tab describes what kind of file the folder tab is representing, below that is the path and filename for the file on the selected folder tab, and below that is the data that the selected file has in it.

In order to modify a specific data value:

1. Select the folder tab that represents the file that you want to modify.
2. Move the cell in the grid to date and column that you want to modify.
3. Type the corrected value in that cell.
4. Select the OK button to save your corrections.

In order to restore a specific data value to its original value:

1. Select the folder tab that represents the file that you want to restore.
2. Move the cell in the grid to date and column that you want to restore. (It will be marked in yellow or red with the original value placed in the Original Value box).
3. Select the Restore button.
4. Select the OK button to save your corrections.

NeuroShell Trader doesn’t modify the selected data file, but rather saves the corrections that you have made and replaces the data you have corrected any time that the corrected file is loaded in the future. This means that if you attempt to use any other program that the corrected data file will not have the corrected values in it.

Additionally, the uses several colors to inform you of important information that is associated with the colored grid cell. The following describes the color scheme for the cell backgrounds:

• Red – you have just modified this cell and changes will be saved when you select the OK button. (Restore value is shown in the Original Value box when cell selected).
• Yellow – you have previously modified this cell. (Restore value is shown in the Original Value box when cell selected).
• Gray – NeuroShell Trader uses this data for possible split information only. The method that NeuroShell Trader uses to combine files has chosen another file to get the data from. Any changes made to a gray cell will be saved, but it will not be reflected on the current chart, unless it changes the split information that NeuroShell Trader needs to combine files.

Finally, NeuroShell Trader uses newer file information to decide whether a split has occurred in the older file. If any overlapping data doesn’t match, NeuroShell Trader applies a split to an older file. If a file has a split applied to it you will see a note at the bottom of the selected folder tab that explains that there has been a split.
