What do you guys think about being able to copy signals between mt4 and mt5

 
Try doing a survey that users prefer to use mt4 or mt5 platforms, and why it is impossible to copy signals between these platforms, is that limited or not.  The interface is completely new and superior to mt4. I want to use mt5 to trade but the signal seller uses mt4, it hinders copying, who has any suggestions to remove this barrier?  is not?
 
You can look at the Market (use this link) because I saw some tools related to it.
By the way, the discussion about the Market products is prohibited on the forum sorry.
