>>How was the hour shifted?<<
This experiment was performed on a very sophisticated platform, not TS. I do not know how it was coded up.

Mark,
Now we are getting somewhere.
This has been my experience empirically. I have a system that trades on 45
minute bars that CAN NOT enter until 10:00CT. I can see the action in the
market as it anticipates all of the "systems" kicking in. It will either run
up in an up trend or run down in a down trend, making the system entry less
effective or necessitating wider stops to account for this. So I agree that
phasing a system could increase performance. I just havn't been able to test
it with 2000i.
How was the hour shifted?

In this experiment, the same system was run on the same data, however, each
time it was run, the hour was shifted by 1 minute. So in the first run ,
the hourly bars were on 9:00, 10:00, etc. On the second run, the bars were
set on 9:01, 10:01, etc. In total, sixty runs were made.

etc. You get superior performance when the bars are phased out by 20
minutes or so, that is, when the bars are 9:20, 10:20, etc.

potential profits with a very large crowd. Does that make sense? Any other
viewpoints?
