Started this day trade based on SPY at the open.
Each of the updates in blog entry were posted on Twitter throughout day in a fairly timely fashion.
From the link:
FINAL UPDATE: the last entry in the puts rode the sell off to the close, netting approximately 55%, $5,500 per $10K in the trade. So the disappointing, even with the first stop loss, day in puts turned out to be just fine. See final updated chart below.
