I think what sahjan was asking for is this.
Most traders that use MG have a fixed amount they use when they trade like if 1 st trade is lost then 2nd trade is X amount and if 2nd trade is lost then 3rd trade is X amount.For example when I use MG I use 2.31 as my multiplier. Whatever my first trade is I multiply by 2.31 and that is for my second trade amount and so on
Also with MG you only want to risk a certain amount of your account balance. You also need to be able to stop if you have too many losses if you don't stop and you keep going then a very good chance you can lose all.
However in reading what you have wrote it seems like you do all of this intuitively meaning you do it on the fly so to speak.
Money management is a very critical part of trading even more so when you are using MG.
It's very rare to have a strategy where you have only a 61% ITM on first trades and never have lost 4 trades in a row
