Rob: To do the overlay, you have to go back and make two new indicators with two separate names, one with the standard deviation line: Std(((h+l+c)/3),28) and the other with the cci line: (((h+l+c)/3)-mov(c,28,s))/(.015*Std(c,28))
Then put the cci line in a window by itself. Then go to the other indicator and put it in the same window, after checking Add Indicator and Overlay.
I don't know what thrilling insights it'll yield, but who knows?
David: I took a look at this indicator, which you posted: mov(c,21,s) - tsf(c,134)
I tend to dismantle systems first and look at the indicators that make them up. You mentioned Dahl's primary trend, and your indicator bears some resemblance to that, doesn't it? They're based on the same principle -- though yours subtracts Time Series Forecast instead of an older moving average -- and plot a similar line.
I tested the system, and with some stocks it missed some long-term uptrends, declining and going under 0 when the stock was still moving up. I'm guessing that this can be fixed by changing some of the variables, as you suggested, and I'll experiment with it.
Still, I'm beginning to think that "mechanical" systems that work consistently will probably be like DNS, which looks for several key things happening with a stock. As I begin yearning to hatch from my newbie egg, and poke my beak against the shell, I see the beauty of his system, with its perfect use of the If formula.
One of my newbie failings is that I'm fascinated with formulas, but it's a superficial fascination because I haven't really looked into the meaning of the indicators. I sometimes wonder whether it would take a mathematician to do justice to that task. I feel almost as if I were abusing the system right now, with my button-pushing profit testing, as if I were painting by number or playing jazz with sheet music. The language of WOW formulas isn't hard to learn, but learning exactly what the indicators really are, how they were conceived, that seems like an enormous task. In a way, WOW makes everything too easy, because I can just plug everything in and busily test everything until dollar signs flash, but I don't really know much more about TA.
So much for newbie philosophizing, newbie soliloquizing. |
