The Dukascopy wiki has a good example of how to write tick data in a MySQL database:
https://www.dukascopy.com/wiki/#Write_ticks_in_MySQL

I would like to use the above example to write tick data in MySQL,
and then read this data back as the source data for the Historical Data Service (IHistory).

Is this possible, and if so, please could you kindly provide an example?

Many thanks,
Nic

You can't modify historical data that the JForex-API or the platform uses.

Thank you for the quick response!

To clarify:
I do not want to modify the history data - I want to change the storage and retrieval mechanism that is used for the data.
I.e. I would like to replace the .bi5 files with a database.

Would this be possible?

Our previous answer also implies that you neither can change the data source.
