Anyone write a Visual Basic program to help their trading?

Agree, VB is easy.
Interfacing to a trading API is quite easy also (about 100 lines of code).
To show what is very difficult just one example from the list:
What is quite heavy: To formulate this in a mathematic form that can be understood by a computer.
What means "effect"?
- Simply "going up" / "going down" (binary)?
- Some correlation?
....
For going up / down: Perhaps 200 lines of code.
Correlation: 500 lines and above.
Same thing for all the other points on the list.
Rough estimation: To implement the whole list 5000 lines of code may be needed and 1-2 man-years!
The main difficult thing will be to
formulate properly your ideas in a mathematical way.
That is a quite difficult task.
Add up sums, and sums of squares, and plug them into a simple formula -- that takes 500 lines of code? Wtf?

wasting time on coding useless indicators in VB is pain in the ass. you can use something like wealth lab to test basic ideas.
even biggest pain in ass is check the code itself, to be make sure that all calculations are correct
here is a good stuff for those with the money.
