Not totally sure I want to get into this but I disagree. Hence probability theory, stochastic process, discreet time, Bernoulli process, Brownian motion, and on and on. Time interval might be the single most important factor in taking advantage of random process.

There isn't? Say you're hosting a party and need to go get some beer. Are you really going to patronize the store again if the clerk tells you that you need to make ten separate purchases for the 20 cases of beer you want?
The size of your purchase is immaterial, it's a single transaction.
It's atomic.
Same with a tick. If you're plugging those ticks into relational database how do you reference the same tick across two different rows because of some arbitrary size limit?
You don't, because the tick is atomic. It's a tuple consisting of three inviolate elements, time, price and quantity.
There's no way to know that each single lot transaction is a separate trader. They could all be coming from someone who's hiding size behind a show-only order.
No chart is better than any other. Any attempt to say otherwise is just a rationalization because any two dimensional chart will always be a visual approximation for the three vectors of price, volume and time.

Prove that statement
Quote from Bullverine:
Ladies and Gentlemen:
I was wondering if anyone could share the market cycles that they have observed and learned from their own experience. Things that seem to happen same time every year/month (example: option expire same time every year or things seem to always go up/down before the X holiday) . Its possible that this might have nothing to do with experience and is public knowledge which I am not aware of, but I would appreciate if someone could shed some light on this.![]()

You're perfectly correct Prof. I was just wondering how you arrived at your conclusion.
Oh and jprad is perfectly correct too.
Prof what you observe is correct in one dimension.
Some good comments in this thread
Quote from ProfLogic:
Many years ago when I was in corporate my field was problem solving and there was only ONE way to begin to solve ANY problem.
Start at the beginning.
&
Break all problems down to their smallest components.
Starting anywhere but the beginning and you are doomed to failure from the start. Start without breaking down the problems to its smallest components and you are doomed. These are standard practices of problem solving which most people don't utilize in their trading which they should.
