ex.4 file made by compiled on MetaEditor5 can run on MT4?

 

My MT4 has be updated yesterday auto; and now I find that my MT vesion is still 4 build 600; and MetaEditor vesion is 5;

my question is that now I open mql4 file before and modify it by MQL4 and then compiled it to get ex4. file; now does this ex4 file can run well on MT4 pair chart?

 

In addition, if I made an EA on MetaEditor 5 by MQL5 and compiled it to get the execution file, does this execution file run well on MT4 pair chart?

Thank you!

1. yes in most cases. But if you find any problem ,please search or ask in mql4 forum .

2. no, I think you can't run an ex5 EA on MT4.
