Thanks for your responses and thoughts on the issue of stopping out or circuit breaking. Here is where I have progressed to (progress is not arrival at a final destination):
You cannot risk manage your way to making money over the long term. If you've got no idea of how to make money, risk managing that doesn't make you money.
Sometimes, when things go down in value, it just means that they have become cheaper and you should be alright with that. Those with a long term viewpoint should stay involved because the purchasing power of your holdings have not changed...if the underlying value of the holdings have not been seriously impacted.
If you have balls of steel and sufficient foresight to make long term valuation assessments, particularly on diversified portfolios, it may be best just to hold on if you can survive the market to market.

My mentality is that I am not trying to time the market beyond saying that I am prepared to be exposed to this investment but may need to circuit-break if something goes against my expectations. I see the concept of pulling a trade under this circumstance partly as risk management against an acute thesis breakage and partly to avoid the boiled frog problem.
Last time I walked through an airport metal detector, I believe my balls were on my person at the time and no alarms were triggered. No item by item strip down occurred either. I conclude that my balls, such as they are, are not actually made of steel. That's what the data says anyway. I am not a Marvel comic hero billionaire playboy philanthropist genius with an iron man suit. I am short one iron man suit, and at least one zero, from that list. That puts me at a disadvantage.
It is one thing to have $50bn in net wealth and see it compress to $25bn when everyone else is marked to market. Who cares? It is another when your lifestyle would be compressed if your asset base is cut in half and you had doubts as to whether the underlying value was fully preserved. If the price moved, part of it may be animal spirits, part of it may be bad news and part of it might be something that never crossed your worried mind before.

I think it is not realistic for me to believe that I can act in that fashion with high confidence. I am not actually in the position that permits, essentially, risk-neutral thinking, for large exposures. I also know that bad outcomes mess with your thinking and it is often best to circuit-break to snap you out of it. Decades of experience have shown me that this is the case even with highly seasoned investors of the mortal variety.
I like this from a book with Ryan_C recommended ("If you can" Bernstein):
We act differently when something big happens and you don't know where that trigger is and how differently you will act ahead of time. Neuro-anatomy and psychology tells you this, unless you have one heck of a well developed Vagal Nerve. You don't even know that you are impaired in those situations.

Nothing stops you from putting on the trade minutes after you get stopped out. What stopping out does is cuts you away from thoughts about what you bought in at to some degree and resets your mind to a position of taking risk again from a zero position. Mentally, that is a better place to be when making calls. This is something I have seen so many times I cannot ignore it.

The option replication concept I use is pretty funky stuff. Calculating it and updating the positions takes about 10 minutes per market. All of the calculations are codified.
In more recent times, though, the rapid rise in markets more recently and huge whip-sawing has caught me flat footed. You sell at the lows and buy on highs with this stuff - that's option replication. Buy-hold would have done a lot better in this highly mean-reverting environment. The price of protection has been large recently.
What now?
