From the link:
That slide into the close saved the trade for the day. After an initial draw down of $1500 (on a $10K buy-in on each trade), the overall net at the close was $7,900 for the day (or 79%) trading the weekly calls and puts (see the chart below for an illustration). Instead of saying the drop from 8 a.m. (PST) into the close “saved” the day, I guess it would be more apt to say it made the day-trade with this system once again great for the day.
