It's only $300, but then again, there's no such thing as ONLY $300. We are in a business that requires attention to detail. That's why I constantly stress that you double check symbols before placing orders, etc.
Fortunately, my $300 oversight was just in the typing of a column posting -- not in the real world. This could have been an expensive boo boo.
So, the actual profit figure on the QQQQ closeout (see previous post) should be $750 instead of $450. The return on risk is now about 16.4%.
Sorry about the miscalculation. I learned from it. Let's hope we can all learn from it.
Take care and trade smart!
