I put in an order to buy 100, shares. Now they know I need shares.

I put in an order to buy 200 shares. Now they know I need shares badly.

I put in an order to buy 300 shares. Now they know I will load up at cheap prices.

I put in an order to buy 400 shares. Now they know to trade it sideways at my price.

I put in an order to buy 500 shares. Now they know to make me pay GAP premiums!

But then.... I put in my order to sell all my shares at $7.00 and they all knew they were up S/C w/o a paddle!
