Hi Wayne,
Nope. I'm a big believer that one of the reasons so many people lose at trading is because they make decisions based on what they think they know based on what they read or hear. And what they read and hear is pessimistic news designed to gain readership. And of course pessimists don't make money.
And it just so happens that Greece is back in the news at a time when we are seeing a short covering rally in the euro. Whoops...now you've almost drawn me into thinking about it.
My trading plan as you know is one page and there isn't anything about Greece in it.
