try this - its has worked earlier for me(but now since using ver 2 am not aware whether it will work or not)
On trade tiger 2 save a chart template. Longer time frame chart template can be saved as ver 2 allows good intraday backfill as compared to previous version.
This file is saved in a folder called Graph template --> Intraday chart.
Its a file with dot TML extension.
Copy, save that file and keep.
Downgrade to a lower version(if you really want to),
Open the chart and try loading the chart template that you have saved from ver 2.
I have done this before upgrading to ver 2.
If any queries pls feel free to ask.
