Hi Bence,
You could use a demo account and just restart it every 14 days. What I did to get around the 14 day limit once FTMO lifted the time limit was to use a 10K Challenge and use 0.01 lots so the account balance will not change much.
When you switch from one demo account to another when the open trades on the FTMO account close the trades on FX2 should still close. Also as long as the magic numbers on the FTMO account does not change when you switch from one demo account to another demo account the EAs will still close any open trades when the EA gets a signal to close trades.
Alan,
I will be off line for the next few hours.
