Hi,

Regarding to this topic, there is already a v3 out there.

On the other hand, this piece of code is the work of a user. Try to contact him if you have issues with it.

I used as you me suggested JForexExcelV3 End users.
It's OK. The file is created when I stopped strategy.
But I want writing lines on file opened that data arrives.

Hi,

As I said, try to contact the user who have created this. You can send him a PM...

On the other hand, after a quick peek on the source I can say that the contents (tick data) are flushed from time to time to the output file. Try to decrease the 'limit' parameter. By default it is 1000, which means that the content will be updated after a 1000 tick or bar has been processed.
Try to set it to 10-20, so after 10-20 ticks/bars are process, the content is flushed to the output.


Success!
