Am hoping to learn as I go as i've read tons but am running up against a gap between knowing and doing. To start, I want to create and application that will go grab historical information for a set of stocks and then daily grab the closing information as well. I then want to calculate certain technical indicators such as certain moving averages and buy/sell indicators that use these averages. Then I'd like the application to "pick" a stock based on the data set. I have a bunch of other stuff I want to do but first I want to get some or all of this happening. I believe this small set should help cement my head knowledge and get me moving in the right direction. I'm hoping it is finite enough to be relatively easy for a network geek turned management who now has some time on his hands after about 15 years and wants to get back to some technical work. From what I read the xCode platform provides the ability to do this within the Mac framework. I have an ADC membership through my company and am fairly comfy in the UNIX environment but past shell scripting and some limited Perl/MySQL stuff I'm trying to forge a new path. make sense? I've read much of the ADC tutorial and architecture documentation. I read, that's what I do but I want to start... Can you guru's shed some light? Thanks in advance.
