Ed,
When the Heikin-Ashi work first came out I spent a lot of time going
through the formula. Since we had not figured out how to master the
display in Metastock by formula or DLL at that point, my only
recourse was to use an altered excel file of the data. Crude but it
worked.
Taking a closer look at the work I came to the conclusion that a
couple of short term moving averages worked just as well. Sadly, that
is the case with most of the TA methods that I have come across.
Somewhere we have been led to believe that all we need to make a buck
is the holy grail of indicators and we too can make millions. Not the
case at all...neither the indicator nor the million.
If you are planning on making money trading you will have to include
fundametal analysis and opportunity. At a recent Senate hearing on
the toxic funds debacle there was a testimony given by a well known
hedge fund CEO. His statement was a real eye opener. He basically
said that once his firm had found something that they planned to
invest in that they would wait for months until the right opportunity
came along before putting their money in. Their returns by the way
were one of the best in the industry.
As far as a Kalman, here is one that I found:
{Kalman Filter}
{Advantage Systems: www.advantage.online.pl}
PRICEE:=C;
Smooth:=.13785*(2*PriceE - Ref(PriceE,-1)) +
.0007*(2*Ref(PriceE,-1) - Ref(PriceE,-2)) +
.13785*(2*Ref(PriceE,-2) -Ref(PriceE,-3)) +
1.2103*PREV - .4867*Ref(PREV,-1);
SMOOTH;
I've never heard of Difussion Indicators so I really can't comment on
them.
Your Modified Heikin-Ashi looks very much like a stochastic of the
daily typical price with the open included.
