That is a mighty large portfolio you've got there.

That was a thought provoking plot, thank you! I would say the green system is very different than the blue system; if I wanted to put together a pair of systems with low correlation, green and blue might be an excellent choice. They can't possibly be more than 35% alike, long term, because blue is in only 35% of the same markets at the same time as green. (And sometimes blue might be long while green is short; we can't tell from this plot.)stancramer wrote:One must be careful to distinguish between "number of active positions today" versus "number of instruments in the portfolio". They are not always the same.
The DMA system has an option to enable Stops. So this will put it out of the market at times.jankiraly wrote:By the way does anyone have a theory why the green line (dual moving average system) isn't perfectly pegged at 100.00 percent all throughout the test?

Jankiraly, I agree completely. I am glad you saw the implications of the three curves! I don't think we have mined all the gold out of this vein just yet.jankiraly wrote: ... if I wanted to put together a pair of systems with low correlation, green and blue might be an excellent choice.

Absolutely. The PGO system (and the Turtle system, but not the DMA system) has three states: Long, Short, and Out. Some of the markets I trade, happened to be Out on Friday Sept. 22.jankiraly wrote:The last point on the red curve looks like it is about 72%. If 72% of the portfolio equals 64 open positions, that means the portfolio contains about 88 to 90 markets, right?
There are two possible reasons. The less subtle one was mentioned by Tim A:.. have a theory why the green line (dual moving average system) isn't perfectly pegged at 100.00 percent all throughout the test? It it a reversing system after all.
However, I didn't happen to enable the Stops, parameter settings are shown below. The more subtle reason why it's not 100%, is a lot of fun to discover for yourself. Insert the code above, run the system, and puzzle over the results.Tim wrote:The DMA system has an option to enable Stops. So this will put it out of the market at times.
The trick of course was to get in to lumber Friday which requires a very short term trading approach. I doubt any LTTF would be in lumber yet, but they might be soon if it goes limit up again tomorrow - possible, it did this 2 days in a row last December.BARLI wrote:Lumber is limit up today.![]()
Anyone's trading Wheat? I am biased its going to 500 cents and then sells off, but we'll see
the problem with limit up days is that there are no sellersLeapFrog wrote:

your prediction is gutsy.
in general:
this structure means up this much.
that structure means no more.
but never this structure means up this much and no more.
i like to see wheat lock limit up again tomorrow.
