I enjoyed your insights about time and sentiment, I agree.

As I listened to you, I had a flash back to my childhood of my mother playing the accordion.

The accordion would expand and contract as the tune was played out.

The interesting point of this metaphor is that with the accordion (time), the tune (price/sentiment) is played out when the accordion is expanding or contracting! And if you close your eyes, you can not tell if the accordion is expanding or contracting, as you listen to the tune being played out.
