Is it common for prudent traders to use much leverage?
I'd always heard it is to be avoided, cos of risks of wipeout.
I imagine it should be kept pretty low...
What is the max sensible leverage for a competent trader?
In air combat, the old saying is that "speed kills." For the combat pilot, speed is leverage. You would not remove speed from the trained and skilled combat pilot, no more than you would remove leverage from the trained and skilled trader or money manager. In trading and/or money management, leverage fuels optimized geometric revenue growth.
The problem is not leverage. The problem is education or the lack thereof. The problem is too many people trading into naked positions leaving themselves exposed to a
single point of failure. Any good systems engineer will tell you that one of the primary architectural elements of a good system is,
Fault Tolerance. Yet, so many traders out there engage in SOP (Single Point of Failure) methodologies, that it has now caused the CFTC to make knee jerk reactionary decisions that are not based on a correct understanding of the underlying problem.
Basic aircraft design 101: Make the Aircraft Fault Tolerant in as many areas of design as possible. This is why some of the better aircraft designs have dual ignition systems, duel power-plants, flight control redundancy, avionics redundancy, fuel system delivery redundancy, etc.
The vast majority of our flights are uneventful and profitable. The vast majority of our trades
can be uneventful and profitable, when we start taking seriously the design of our trading methodologies and include at least some degree of fault tolerant trading into our daily lives.
Most highly successful traders and money managers already know and implement this into their routines.
