When a sharp directional move in a news trade ends, it can behave in ways which are random. But it can also show a pattern formation. This is typical of market behavior. The prevalence of patterns and the unpredictability of movement suggest both an order and an randomness.
When a news move ends, it enters an entirely new phase where its direction becomes contingent on underlying order, but as this order creates surfaces upon which it moves against, the direction becomes random. The move can reverse sharply, but sent there by the end of the move.
Can it be considered that this retains an influence on the move as it reverses. It may, and may determine what happens next. Thus again, the direction is random, but the underlying order creates a pattern. Hence why patterns are only clear after the event, and as they form, may take different outcomes.
