I've developed a service which can clone trades from FXTS2 to MT4.
Also, any indicators/strategy with alerts could be easely adapted to execute orders in MT4 (FXTS2->MT4, MT4->MT4, MT5->MT4, TradingView->MT4). FXTS2 executer under development as well (so you can execute orders sent from FXTS2, MT4, MT5, TradingView in FXTS2).
This software is in a closed beta stage for now. Let me know if you want to try it out.
