Metrics accelerate reactions, but destroy sequence.

Metrics create a sense of constant feedback. Any change seems like a signal to act, and attention gradually shifts from planning to reaction. Thus, discipline begins to depend not on the structure of decisions, but on fluctuations in indicators.
The problem is that metrics change faster than the logic of the market itself. Following them leads to fragmented actions: decisions lose coherence, and the strategy turns into a set of reactions to external stimuli.
