Are you saying that meaning after a 10K order the price may go up or down, so wait and see if that happens then place 10K more if it stays the same or goes down, etc.? I don't think you're suggesting a 10K order would influence the price, you're just saying wait and see where it goes throughout the day(s), I agree. No sense blowing it all at .10 and then seeing it's at .09 an hour later.
