Hi Bence,
I cannot use the FTMO robots on my Oanda. com account because when they show profits in the FTMO Challenge I get nothing but losses in my Oanda account. So, the historical data can be quite different with various brokers.
As to your question, it is possible that on some weeks the two accounts may show the same trades but on other weeks you may see slight differences. One way to make them the same is to use a copy trader so you can copy the trades from FTMO to FX2. This is something I want to try myself but have not done so yet.
Alan,
