Boca & Dale, thanks for your MM comments! I'm getting on the real ride now, having taken the courage to move from tiny lots to positions that matter for true profit. I.e. I have ended up now using using the 1.8% margin for RTS and about half of that for VS and DMS, as the latter ones tend to be open longer and have bigger potential drawdowns. Currently my open trades total about 8% margin. I made a small number play about the potential loss if all my positions turned against me and hit the rock bottoms that I'm ready to take. In that case I would loose 25-30% of my account. I think that this exceeds the advised total risk that you should ever take, but on the other hand I think that the probability in ending up in such a situation is rather minimal, as all your trades should skyrocket in the wrong direction at the same time. Maybe that "total max risk" could be some sort of advisory measure as well, maybe setting the limit up to somewhere as high as 50%?? Using the margin for MM calculations is at least quite handy, much easier than doing some sort of inter-system/inter-pair weighing that I originally thought.

It's just an ordinary Finnish word, though perhaps not that common in this forum...
