Hey Kris,
Glad to hear from you. In the course, I showed scaling with the EURUSD EA, which uses SL of 30 and TP of 60.
Now when the EA trades on multiple currencies, they all use different SL and TP.
However, if you want to use the scaling with 1:2 you can set SL of 30 and TP of 60 to any of the EA. It will have a worse backtest but it will be easier for you to manage it.
