Custom history period for signal provider

 
Good day all,
I as now want to be a signal provider here on the MQL5 web site, i need clear/delete/erase/not show... my history before and ONLY before May the 17th 2016.

In other word, i need to ONLY show the history from May the 17th 2016.
To only show my positive result after a long and very hard work on the market and myself.

For example, the feature is available in the myfxbook website (like the attached file).

How can do that here ?

Thank you
 
That is not possible in mql5 signal system.
 
Hello,
thank you for your answer.

I demand to my broker to delete my history...
Regards.
