Very interesting.
I do not understand why people are so pessimistic here about Trading.
It is very feasible to make a 10-20% monthly return from it. (Depending on what you trade with). Futures are the most professional, regulated, "cheap" (in terms of comissions) and profitable products to...
https://ibb.co/guBuPd As the title indicates, I want to calculate the Probability of a stock price reaching a determined point, by considering the system as a random walk model, and after that, to compute the so called "maximal curves". I found the whole explanation in this article...
I am not sure. in slipping friction all the surface of the body is sliding against anotherone, in rolling, just a part is sliding.
is it?. Again, excuse my ignorance
Hello!
Excuse my ignorance. The forum is full of difficult questions so I even feel a bit ashamed of posting this, But that is the only way I can learn.
I do not understand some concepts stated below in the images, and I am not able to grasp what is being said. For instance, I do not know why...
First off thanks for your interest and sorry for delaying in responding, I was on a vacation.
The rim is made of steel or plastic. I do not have any standard deviations nor mean for the fall times, I do have for the falling position though (Which tends to be always at the same part of the...
I thought about it. There may be other variables which are not regarded by the model.. It is unlikely though, as the roulette I took the data from is covered by a kind of glass ceiling (thus less sensitive to the environmental conditions), and it is automated.
I think there must be any...
Hey guys!
I have been working on this project during some time.
First off, do you all think that this is possible? Of course, as we all may know, the roulette is a chaotic system, very sensitive to initial conditions, although deterministic.
This means that small errors in the...
which values for phi have you used? (I mean, for the second parameter to find out in equation 42) I already know its right phi value, which is 6.19
Still, using that value, my bisection does not work.
Thanks!
Oh of course, sorry.
{0.75, 64.36 }, //Time of a turn, final space in radians
{1.383, 33.50 },

I think the whole code would be a bit tedious to read. I have gone over it some hundred of times and there is no mistake in that.
here is the function that I have to minimize (43)

And here is the data. http://es.tinypic.com/r/d4l8j/9.
Altogether with the...
By the way. Can someone explain me what finding a root going downhill means?
And how can I minimize that function (.16) if its "y" values (I mean, fx) are all of the same sign? (they should have different sign so that bisection could be applied)
Is it possible to bisect in that case?
thank you all!
Perfect. I designed the algorithm to perform it in that way. The problem is though, that the signs of Fx for the different values of b to bisect, after just one iteration, are the same!. Then no bisection step is taken. I do not understand why this is happening as 1) the function I am minimizing...
Hey guys!.
I need to use this method of minimization.
The procedure to follow is explained here:
http://es.tinypic.com/r/35mmtg0/9
However, I do not fully understand. What do I have to do?
What I got from the paper is that I only have to minimize the equation 15.7.16, by using bisection. With...
Thank you all for your comments
Yes, I knew about the gambler's falacy. I am stating this question because it impacted me that dozens had the same probability as sectors, due to the physical reasons already stated.
What you are saying about the biased roulettes is interesting. I have a doubt...
