"no emotion or angst involved"
yeah, it's a beautiful, never lose mechanical strategy that will pave the way to financial freedom - the holy grail.
whatever, it's an edge and that's it. do you hold when it gaps againt you half a point and look to get out even, or maybe a profit (don's the king at this) ??? do you take profits at 20 cents or hold out for 50 cents? if you do hold out, and it gaps down 50 cents (WHICH THEY WILL), will you experience any angst?
