"For simplicity but without loss of generality, assume there are n past price changes, each of which is either UP (1) or DOWN (0)."

You know, this is the kind of thing that makes me wonder about how much quantum computation is going to change the game.

Where we aren't just calculating ups and downs but superpositions between the two.

Digital is a framework built on top of analog. Boolean logic is the foundation of all of our modern computing, and so we built all of our circuits around the ability to handle HIGH and LOW signals. What your describing seems to me like you're saying that leveraging an analog signal is the benefit of quantum computation. If so, I don't really agree. If not, then I misunderstood.

Either way, I suspect that the superposition between the change in value and the change in time, in relation to all of the other superpositions in value/time changes, is the true computational power of quantum technology.
