Hi Miguelacho,
The reason why you are getting incorrect data coming out is because you have selected "{Timestamp}" which is a field relevant only when outputting tick data (as opposed to bar data which you have selected). Instead, you should use the token {BarBeginTime:yyyyMMdd} to display the bar's begin time.
You can get quickly up-and-running by starting with the pre-defined "Generic bar format (comma-delimited)" and then, once you are more familiar with the process, you can tailor this template format for your needs by subseqently selecting 'Custom'.
There is a full description of all the fields in the manual, and you can also check out our video on this topic here:

Make sure you switch on YouTube's "Close Captions" (CC) so you can see a description of the process as well.
Regards.
