Hi Boyan,
If you are not in the United States MT4 it is still available right now. MT4 is not available in the US. I have to wonder how much longer MT4 will be available at FTMO outside US. Also, some of the prop firms are no longer allowing US traders. The prop firm business is in a state of change and has not yet matured.
I know trade copier developers are working on MetaTrader to DXtrade apps but I don’t know of any at the moment. I have been researching for them myself. There are trade copiers between MetaTrader and cTrader and some prop firms are moving to ctrader.
Alan,
