answer 1: This is explained in the cheat sheet you can download from the FTMO course, However, I will explain how I would use the scaling plan for a 10K account. When I would start the challenge I would start with a lot size of 9.3 lots. Once I have $300 profit I would increase the lot size to 0.9 so that the next time the EA entered a trade it would trade with a lot size of 0.9 lots. Then once the account reached a profit of $900 I could increase the lot size to 2.7 lots. The idea about how much to scale up is so that if the EA hit the SL the account would be reduced to would not exceed the daily amount of 5%.
answer 2: This IS done by how you set up the first 4 lines in the FTMO EA properties.
answer 3: The TOP 10 Forex robots do not adhere to the 1:2 loss/win ratio.
