Yes. There seems to be a common thread here. You are taking on way more than you, or really anybody, can handle. I mean, seriously---a program to model the stock market? That's why everybody else keeps bailing out. Anyway, if you get a bit more realistic (don't read: less ambitious), then I'm sure you'll be a lot more successful.

Failure is actually a good thing, as long as you learn from it. And it looks like you've got plenty of material in that regard.
