I always see lots of discussion on this forum about consistency - whether it be consistent systems, trading methodologies, etc
the simple facts [ not an opinion] are that if you look at the most successful traders and investment managers in history [ i.e. a track record of at least 20 years compounding somewhere around 20% per anum - incidentally only 4 exist above 20%] then the one feature they all have in common is consistency is not achievable for long term success. In fact one could argue the more consistent a strategy is over the short term the less likely it is to work in the long term. The simple reason is that its likely to be optimised and curve fit.
Robustness is far more important than consistent and the 2 are not related
