Same thing happens to me when i play the market. I think I have figured a reason why guys like us always get screwed.
It is a simple reason, there are smarter and more sophisticated investors that have the resources, money and technology, to know what the average investor (you and me) is thinking and will do and knows how to make (take) money from us.
They are smarter and they will almost always win. They have the money to move the market where they want. You can't beat them, they know yours and the markets psychology very well.
Well hope this is understandable and makes sense.
