The following prop firms have blocked access to their DXtrade APIs, therefore it is not possible to add accounts in Duplikium.
- InstantFunding (dxtrade.instantfunding.io)
- MyFundedFX (webtrader.myfundedfx.com)
- FTMO (dxtrade.ftmo.com)
In the meantime, we can recommend you look for prop firm supporting cTrader, as with Duplikium Trade Copier you can mix all MT4, MT5 and cTrader.
