The OP has stated and backed up his goals for letting a system make money for him as he does other things.
Two others have commented on how it is from their point of view:

Quote from pismo10:
For 1 min EURUSD over the past year it works sort of. For one year on the ES it loses huge. You can play and optimize the rest of your life and get nowhere. Works great on 15m ES but not at all on 5 min ES, how good is that? Is that ESZ08 or @ES (which isn't real)?? Maybe 23 trades over the last year on an hourly chart, so watch it for 15 years to see if it really works....This is the story of mechanical systems more often than not. Nonsense.

and j:
Fundamentally, this is a one-minute breakout system. That sort of system is quite robust when used with markets that trend more often than not.
An index market is primarily mean-reverting due to hedging activities, using a trend-following system there is suicide.
The OP is probably out of luck at the PA level he is considering. For FX as cited there is more than less trending (the condition for the OP's notion to work)
As others felt and have expressed, I thought the thread was dealing with an actual retail apporach instead of just a notion.
I practice, meaning trading, a trend following system in an index market. I do notice that there are players who use mean-reverting systems. I monitor market drift since it relates to the mean- reversion "tells" I front run. From these factors I conclude that mean reversion strategies are played on index trends. The relative size of change in price (where money is made) is larger for trends than it is for mean reversion.
What would idealized waveforms of trends and mean reversion look like? The trend waveform is the carrier of the mean reversion. So money is made in different ways for each endeavor. Trend following is just a matter of trading price movement; mean-reversion is more sophisticated and pairs of instruments are used.
A key question is how money is made all the time in either approach. Mean-reversion does employ one of the OP's principles: being in the market all the time. Big capital cannot lay idle.
The results of each approach is generally not known to the public and especially retail traders. Several graphs were presented that centered on the OP's notions. They proved that money can be made in trending markets and money is lost in non trending markets (for which the OP made no provisions).
Mean-reversion does not depend upon trends since the pairing that is done eliminates trends but not drift, basically. Drift is the variation in the index and its underlying. When the drift hits 4 units (smallest trading variation, tics) usually BOTs (and in the past floor traders) kick in activily and tug the drift back to 0 and overshoot it momentarily.
I really appreciated ironfist's contribution on how he approaches his PA trading and how it related to the OP's difficulties in "non trending" situations as non trending was defined by the OP's system performance.
What this brought out was that on various fractals (three were mentioned) there were 8 combinations of trending possible. This is what makes trend trading so much more rewarding than mean-reversion trading. It is also what makes it possible for a retail trader to use an ATS that does not require attention and which is operating in the market all the time during RTH when liquidity exists. More than PA is required, however. That is more or less OT in this thread.
I slowed down the OP's trading turns (reversals) by a factor of about 5 by going to one fractal slower and that fractal was contained in the slowest fractal envelope. Slowing it further by at least one third more would have just yeilded 1 trade over the duration examined. pismo 10 points out the same aspects occur by just using the OP's approach on slower and slower fractals.
By slowing any approach down more and more, more of the places where losses occur are eliminated as we see. This is a good path to follow for the potential learning trader.
We also saw that this was not possible for the potential learning trader. We all can agree on that. This line in the sand that occurs where differentiated beliefs do not allow a person to explore any more is difficult to address because it is automatically and permenantly kept off the table.
I feel the OP made a good objective first pass on a huge opportunity. And anyone can be oriented to want an unattended system that makes money based on not wanting to spend time at a display. It looks like going out and purchasing such a solution would be the thing to do.
Also it is not difficult to see why a purchase isn't possible: no one here has one(See sponsors) and those who do (See expert traders), do not have them for sale.
If the OP can make the start he and others did, then how would such a person proceed to finish the job. Add the necessary parts is the answer.
One of the most exciting things in the world is to go through that process. I hope the OP does and I hope others do, too. It turns out to be a very counterintuitive process. At every choice along the way, journal the choice and when you proceed to a dead end, retrace your steps back to the place you made the wrong choice and take the counterintuitive path.
Draw out the answer first as ironfist did roughly. Maybe refine the rough out a little. That is the answer: all profitable trades one after another. You know, collectively they are being done; the T&S says so. How does one entity (person or ATS) do these trades in the market and be in the market all the time? In the limit, all exits are entries in the opposite direction at that moment.
Why do people look at the axis they do? Why can't people look at the other axis instead? Price doesn't matter. Time is what matters. Price measures value. What measures timing? People are what is measured; the other time based variable.
A person comes to a fork in the path. He choses Price instead of people or both Price and people. He goes to the Price dead end. He will not come back to that decision, ever, which he made at that fork.
