In July 2009, I made my Day at a Time (DAT) very short-term trading system
available to serious traders.
I offered a limited number of DAT systems, and they sold out.
DAT has done well, going forward with over 76% accuracy for over 2 years after release.
But there is always room for improvement, and that is where Andrew Black
from New Zealand has helped me!
I've had many requests for another very short-term trading system
in the form of an even better version of DAT that uses the VERY POWERFUL
Day of Week Pattern, which forms the basis of the DAT system.
As one of the best mentoring students I have ever had the pleasure to work with,
Andrew Black impressed me with his analytical and system development skills,
as well as his quick grasp of my trading ideas.
(see Andrew's bio at the end of this announcement)
Using his considerable skills as an IT expert and accounting software specialist,
Andrew was able to take the knowledge I gave him about the Day of Week patterns
and systems, and add it to his analytical expertise to develop and refine
my Day of Week strategy to many markets that had previously eluded my expertise.
Andrew did an outstanding job. His back test and forward test, and out of sample histories,
blew me away. I had to check them over and over to make sure I was seeing
what I thought I was seeing.
His work was so outstanding that I asked him to go over his procedures
and results several times to make sure he was developing the system correctly.
And he was right at every juncture.
The reason I asked him to check and recheck his work was because the
trade histories for 2011 were stellar even though 2011 data was NOT SEEN
by the program as part of the optimization process!
I asked Andrew to develop the system fully on 18 markets using % stops and $ stops
and to allow users of the system to compare both approaches.
