Question: Mechanical systems easier to follow on EOD basis?

["Bryan Finnegan" <TeamData@xxxxxxxxxxxxxxxx>]

Like many others, I have written what I believe to be fairly decent
systems.  Most of my focus has been on an intra day basis trying to get on
board 2-5 day swings in the S&P and bonds.  Some of these systems are very
good if you have the ability to blindly follow them.  My problem is that
during intraday trading I find myself with so much time on my hands that I
inevitably try to apply myself by questioning every move my system makes. 
Of course the second guessing always kills me, I know this but I can't keep
from overriding the system.

Questions:
1.  How have others dealt with this?
I know there are brokers who will follow a system for me, but I don't trust
giving them my ela code.

2.  Is it easier to switch time frames from intra-day to end of day?
Maybe switching to EOD will limit the time span I focus on the market,
which perhaps could minimize the temptation to meddle with the system.  

3.  How have others dealt with this demon?
