This is very interesting. About 6 months ago I also began experimenting with just such a system. However the "factor" is based on the Fibonacci sequence.
I implemented it as a software program and ran some backtests that had promising results. However it still needs tweaking. I haven't had a chance to add the tweaks yet as I've been busy with quite a few other projects.
It's good to know others have independently come up with similar systems. That gives me even more confidence in it and just might push it up my priority list a bit.
I'll look forward to seeing your respective systems.
It sounds like a whole lot of people been on the same wavelength.
>What do you base your progressive factor on?
It's a tough one to explain. The factor was and still is a way to curb buying and selling. It's kind of like SAFE. At first it became apparent that I could run out of cash or shares if I didn't have a governor of some sort. The big problem and bugaboo is: What to set the Factor to? That is still a problem. I wish there was a way to have a variable factor that would adjust itself to the portfolio value or maybe share-value-to-cash ratio.. This could be done I'm sure but it would have to be done by someone much smarter than me. I cant seem to figure it out.
These numbers I'm using could be wrong! So be careful out there. I must do more testing.
