Hi Lydia,
I know the video shows Petko installing 30 EAs. Just do what he does for the first EA. Yes, the EA has to be used on the EURUSD chart and the H1 time frame.
Note: This EA has not been working for the FTMO Challenge since March 2023 as it has been losing since then. Petko updated the EA in his FTMO course but it too has been losing recently. Petko has not updated the EA recently!
