You export EA to MT5 in the exactly same way as you do it to MT4. However, there are several differences:

1. MT5 doesn't show the exported EA directly in the experts list.  You have to open the MetaEditor, to find the expert in the Experts folder, to open and compile it. After that, you can return to the MT5 terminal and to run the expert.

2. MT5 doesn't support independent trading of different charts of one symbol. If you do it, it will apply the trades to a single position. For that reason I removed the "Magic Number" from the expert properties to be sure that someone will not try on different charts with different magic numbers.
