Are you trying to say you gotta look at the data and be flexible? Sounds like you are turning onto the discretionary highway. Have you made a wrong turn? Best make haste and get back to the arctic circle and the frozen algos
Not really. Just redundantly emphasizing that no free lunches exist. Discretion has its place in strategy design and research, but no place in the heat of battle. An algo is pretty much dogshit without expert discretionary input.
