exactly. what's this nonsense about sizing up?? haha. don't worry about it in something like the ES, you won't have any impact. you can trade a few thousand without moving it much at all at any point during the day. you think if you sell a 500 or even a few thousand lots the market is gonna move off of that? now, if you're talking something like the cocoa market then it's a little bit of a different story. anyway, if you have to ask you're not big enough where it will matter
