To summarize, it is not a matter of using one definitive measure to assess a system, but by identifying which factors are important to you and then targeting systems that fit your requirements.

Are you a conservative trader that likes to use low leverage?

If so then a system with low max positions is more suitable.

An aggressive trader on the other hand can use systems with a higher number of max positions.

A trader who likes holding trades for days can target a system with long holding periods and so on.

Many traders look at reward before risk but it is an important mindset to put risk before reward, and by using the maximum drawdown data, the client has the ability to assess previous losses the system has
encountered and allow for these losses when planning their portfolio.
