# how does tick exactly move?(tape reading)

I'd like listen to your comment on how exactly the quote tick moves. I suggest there must be many kinds of motion of tick with different causes. I would shrug on a general statement saying it is simply all because of demand and supply. I noticed there were wonderful threads about tape reading. I like to extend the topic with concrete examples in discussion.

Let me start with an example which is the motion drive by normal demand and supply. For simplicity, let's make the assumption that there is only one exchange.

Okay, let's roll the tape.
T+0: P+0 10x10 P+10
T+1: P+5 1 x10 P+10
T+2: P+5 6 x5 P+10
T+3: P+5 5 x 4 P+10
T+4: P+8 5 x 4 P+10

In this simple case, the outside buyers drive the tick&last price up given the fact that the market make do not insist to hold the offer.

I know there must be many cases and interpretations in the real-world. But let's start with simplified cases to understand the ticks. Please present your favorite examples, either simplified from your memorable trades or watch, or a hypothetical one. Thanks. And similar academic or nonacademic references on the topic are welcome.

Thanks.

you wasted people's time to read 4054 digits among which there are:

182 0
821 1
421 2
56 3
750 4
494 5
583 6
566 7
54 8
127 9

Which of you finger likes the '1' key?

4. ### bungrider

see, you're getting better at this already..

5. ### qdz2

yeah, i bet it one of fingers on your left hand

7. ### qdz2

Someone would say it is just demand and supply. Well, that's right in many if not just some cases.

Let's see.

T+0 P+0 2x2 P+10
T+1 P+5 2x2 P+10
T+2 P+5 1x1 P+15

Demand doesnot increase. But it is the guy move the bid up and cancel out a supply.

8. ### bungrider

i think more people might reply to this if they understood what that meant...??

i'm not sure what your T&S up there really means...?

9. ### chasinfla

I've noticed that it goes up and down, though seldom at the same time.
