# need help with Inertia for an technical indicator

Hi guys
I am currently programming indicators in Easylanguage Powereditor for Tradestation 2000.
Now I heard that some guys are using Inertia as an indicator. Now I did read thru some formulas and do not understand it.

Is there someone that can help me.

I am not sure just what is your question.

My understanding is that your question is not about the programing language itself but is about some of the concepts which you wish to program.

What is inertia? Basically it is the mass of an object which determins tha amount of acceleration which the object undergoes when a force is applied.
It is related to momentum, a quantity which is conserved (unchanged) during interactions.

What are the formulas which you have difficulty understanding?

Inertia is a very well understood principle of physics.  It's been tested in at least hundreds of experiments, and found to match experiment to within miniscule tolerances.

Nobody has a formula for what drives stock prices.  It's tempting to try to model stocks with physics-like equations but In One's Humble Opinion, that's about as accurate as reading tea leaves, perhaps less.

If you think the rich guys have access to better predictors, remember the Hunt brothers who blew over \$1B on silver a few yrs back?

a = r A
T = F r = m r a .
T = m r a = m r (A r ).
T = (m r 2) A.

f = force = ma                   \
t = torgue                           -----   is this correct ????
m = mass                          /
A = angular acelleration     /
a = linear aceleration       /

linear aceleration ...... where or how do we work this out ???
angular aceleration ...... never even heard of this???

you need to learn Newton's 2nd law

linear aceleration : when all the movments and forces are limited/directed in a line,each object moves only in one path (maybe in 2 direction on the same line, like objects under a spring)

angular acceleration : when some of the objects moves in circles, or even part of circles (pendulum, carousel)

The equations are correct
-
"linear aceleration ...... where or how do we work this out ???
angular aceleration ...... never even heard of this???"

acceleration is the change in velocity per unit time. How you work this out depends entirely on the specific problem you have.
angluar acceleration is the change in angluar velocity per unit time.

If these concepts are new to you and you really want to use them you MUST learn some physics. Talmash had provided a good starting link.

Ok thanx
I'll get started with the link that you guys psoted.
