Looking for info on TASC "hysteresis" MA crossing of Bands method.

Hi all,
I read a few months ago in TASC (January 2009 I figure) about an article applying 'hysteresis' to an MA cross.

The basic premise of the method was to instead of rely on simply an MA Cross system. To replace the longer period MA with bands (either Bollinger or Keltner) to use this as a sort of a filter. Openin a position when the upper bands were pierced by the MA and then closing when the MA crossed the center line again.

Does anybody have more info on the article? the mag is off shelves now and I didn't get a chance to explore the articles more.

Has anybody had experience with something like this?

Thanks
Stuart

Hey, interesting idea. I looked up the word 'hysteresis' and the definition I found (wikipedia, a free site, not to advertise for them) said
If the system has hysteresis, then this is not the case; one cannot predict the output without looking at the history of the input, i.e., the state of the system for a given input. In order to predict the output, one must look at the path that the output followed before it reached its current value.
-- Exactly like chart-reading. Then it said
Human-designed systems will sometimes intentionally exhibit hysteresis. For example, consider a thermostat that controls a furnace. The furnace is either off or on, with nothing in between. The thermostat is a system; the input is the temperature, and the output is the furnace state. If one wishes to maintain a temperature of 20 degrees, then one might set the thermostat to turn the furnace on when the temperature drops below 18 degrees, and turn it off when the temperature exceeds 22 degrees. This thermostat has hysteresis. Let us say that the temperature is 21 degrees. Given this information, one cannot predict whether the furnace will be on or off; it's not possible to predict the instantaneous output of the thermostat, knowing only its instantaneous input.
-- Exactly like range-trading type of chart-reading.
So I looked at a band I like, JB Center of Gravity (no repaint), and a moving average (picked linear weighted at 34) and voila! Moving average is no longer a lagging indicator, it's now a midline for PA.

Oh, okay, I get what you're saying. Since the longer-term moving average can act like a midline, you make it into a moving-average band through making deviations above and below the chosen m.a. Is this a popular idea? Maybe someone has this already programmed.

ok, I got a copy of the article (Thanks by the way, you know who you are) and have had a chance to look it over a bit. will post a system under trading systems soon. Look for Hysteresis in the subject line.

Peace
