As a trading instructor, the question I probably get asked the most is in regards to time frames.

In my last two articles, I wrote about the equivalence between two popular option positions ? the short put (with no stock position) versus the covered call (long stock and short call). Today we?ll finish that up and talk about out-of-the-ordinary situations.

A common complaint from traders is that they seem to exit from profitable trades too soon.

Wal-Mart, Tesco, Costco, Sam?s Club, just to name a few. These are some of the biggest retailers in the world, huge operations that make fortunes in revenue. How do they do it? What is there big secret?
