Extension files .ex4

Everybody
Any hints how to upload such files (with indicators) to meta trader? It is not recognized by my system!

Jeff, these are MT4 "executables" rather than "extensions".

Simply copy them to the appropriate folder (explained below), then quit and restart MT4. Then when you press Ctrl-N to open the Navigator, open the "Expert Advisors", "Custom Indicators" or "Scripts" trees, and drag the appropriate EA, indicator or script onto your MT4 chart.

Here are the folders into which to copy the objects:
Expert Advisors: c:\program files\<mt4 broker name>\experts
Scripts: c:\program files\<mt4 broker name>\experts\scripts
Custom indicators: c:\program files\<mt4 broker name>\experts\indicators

More info on MT4 here. In particular, see the section titled "Adding custom-defined indicators to MT4".
