I have already a much more powerful and effective MM system ready to be built in an EA (that basically do the same as you say, following a loss use a more aggressive lotsize, and following a win use a less aggressive one).
That is only half however of this equation, the other half is to loe a system which would somehow have at least 50% winners (with let us say 1:1 rr).
Now it seems like it's simple to reach the 50% mark, simply buy or sell randomly, tp and sl same size, the outcome will be 50% right?
Incorrect, you still may have 5-10-20 consecutive losses which would destroy your account.

Not Simple!
