Rudd...for all I know you're a decent person. there are lots of sites online where you can learn the basics about markets and trading. maybe you have lots of money and it doesn't matter to you, but if not and if money does matter, you need to brush up. the stock market can be brutal even for those who know a great deal and have a wealth of experience. based on your posts, you are cruising for a big bruising. by no means are you alone in this way and it is not in any way shameful. having at least an idea of what you don't know is one aspect of wisdom...
It's not the buying and the selling, but the market makers who set the price, the bid and the ask, as I understand it. They can do whatever they want. It's usually based on supply and demand, as I understand it. So you're barking up the wrong tree, as I understand it.
