    I am automating my system, and I am finding that alot of my rounding is really skewing things more than i want. For equities, How many of you round to the nearest 100 shares vs. 10 shares? Does this cause more slippage? Any other concerns? I am currently rounding down to nearest 100 shares, but am thinking about rounding down to nearest 10 shares -- concerned that it might be more trouble than its worth. i use all market orders....
