You don't need to rename ind4to5.mqh to ind4to5.mq5. Neither you need to compile it.Sir pls correct my mistake i really need it to change
MMA_W3Adeviation.mq5 is the file you are trying to convert, it should be inside the MQL5\Indicators\ folder. You also need to add the line
#include <ind4to5.mqh>to its code - somewhere near the top. Only then, you should try compiling it.
