Suppose you are given a 70% accurate egy (r:r = 1:1)

How can you decrease your risk further?

Can you select pyramiding?
Can you select clustering?
Can you select some-sort of averaging?
Can you split up your first entry-amount re-enter at better prices(pullbacks)?
Which risk-management technique will probably be most acceptable for this circumstance? (taking probability fixed r:r into account)

What are some of the most usual position-sizing egies to decrease risk?

The objective of this discussion :

Its hard to increase probability of the majority of mechanical systems , after a certain point. Should you join a 70% accurate egy with a different 70% accurate analytical-stuff, the systems probability gets decreased. So most egies can't be enhanced via more technical-analysis.

Subsequently, money-management is the only method left to lower the risk which signifies improvement to the machine (if there's any room for this).
