Adaptation to changing system

Guys,

Of major importance in this game in my view is adaptation. This could be evolving your systems, trading multiple systems / styles, trading different types of market structure etc.

Please share your thoughts / learnings? How have you adapted or managed changing markets? Or do you disagree that you need to and focus on 1 thing and do it well?

Good systems presuppose change. The trick is to find a system that is compatible with its user.
