Scottrade vs e-trade vs ??? [View all]

Here is what I want and it isn't obvious to me who offers what.

Let's say I buy a hundred shares of X at $10/share. I want to be able to "program" some trades so I can just relax and not have to watch every turn of the market. For example:

1) If the stock goes to $9/share just sell it all and exit that position

2) If the stock goes to $12.50/share, sell 25 shares

3) If the stock goes to $15/share, sell 25 more shares

etc

Does Scottrade or e-trade let you do things like this? Or would I have to resign myself to watching everything closely everyday?
