Has anyone successfully implemented this? What does it really mean to trade "100% strategic and 0% tactical"? After spending hundreds or even thousands of hours developing edge-based models I finally got tired of this and started pondering what the hell is strategic trading and where is the actual difference from tactical trading? Strategic vision is supposedly finding out what happens in the market, i.e. what type of behaviors exist, and creating simple trading strategies to exploit each of them. Now if you take any simple strategy, targeted at some common behavior, it most likely won't have any edge (won't beat 70% of random entries consistently) and to make it edge based you add filters and patterns and similar stuff to weed out trades where targeted behavior does not "happen". What happens is you end up with edge based trading model which is very "tactical", i.e. gives too much attention on when to buy and when to sell. Here is an actual Acrary's quote that's particularly interesting: Does this imply that those simple strategies are not edge-based? I wonder how strategic trading really looks like and guessing it is a collection of simple strategies (not necessarily edge-based) and a central model (or algorithm) that decides which strategies and how much of them should be currently traded. Acrary mentioned immune response model a few times, but no more details were disclosed, so a lot of stuff is left for free interpretation of what strategic trading really is in practice. What do you think?
