Well "Check Spelling" wouldn't have helped, since wining is also an accepted English word.
Which probably answers your question, for me at least. Basically, after a certain number of months trying to make a consistent profit trading, and finding it nearly impossible, the frustration is enough to make anyone an alcoholic.
So, having turned to wine (red, white, I'll try both depending on mood) out of exasperation from the stock market, I spend my days wining, and if I'm lucky, also dining.
Of course, I could spend my time complaining about how difficult it is. But that would be whining, which is not what he wrote.
