mas, can marketiva trading use InstaForex MT4?
If direct login doesn't work, the company names are already different. When you register at Marketiva, use the software provided by Marketiva, and the same goes when you register at InstaForex. Use the software (Mt4) provided by InstaForex. If you want to use Mt4 at Marketiva, then please open an Mt4 account with that broker.
Thanks
To Toif,
It is not possible. Because the MetaTrader application that is already labeled with a broker can only be used to log in to the trading server of that broker. It cannot be used for other broker trading servers. Therefore, in this case, you should use the official platform from the broker you are using.
Hope this helps.
