Hello traders,
I just shorted 5 (five) pieces of BDX, as suggested by the PnF/RSI system. (Do you think I diversify enough?

) I wanted to know if I really can submit an order for less than 100 pieces. Sure I can, serious slippage, though... I wonder what difficulties I will have, when I want to liquidate this position...
Anyway, I looked at the bids and asks of this stock, and found the following:
BID ASK
Price Size Time Price Size Time
49.81 1000 10:35:11 51.63 1000 10:35:11
49.80 1000 10:35:13 51.62 1000 10:35:13
then these are cancelled, and the new one:
BID ASK
Price Size Time Price Size Time
49.96 2000 11:35:20 51.78 2000 11:35:22
I guess there is one person behind these orders. If so, why would someone do that? Any effects on price?
Have a good day!
