Yes. Local Trade Copier™ works with Metatrader 4 and Metatrader 5, and you can copy trades from MT4 to MT5 and MT5 to MT4.
It is necessary to understand that the MT5 and MT4 come as separate computer programs because of the different architecture between Metatrader 4 and 5. But you’ll get both programs with the same subscription.
Note that copying from MT5 to MT4 or MT4 to MT5 will have some limitations. For example, MT4 does not have “BUY STOP-LIMIT” and “SELL STOP-LIMIT” pending orders like in MT5, so these cannot be copied. But of course, the regular pending orders like “BUY STOP,” “SELL STOP,” “BUY LIMIT,” and “SELL LIMIT” can be copied between MT4 and MT5 and vice versa.
