ALL or NONE - up until january 2009 there used to be an option called ALL or NONE that i found very, very useful. one could place a buy / sell order, check A o N and forget about it. now my broker splits my buy / sell orders, regardless of the size, into two / three / four or even five orders and charges me commission as many times. on the other hand there are the HFT (high frequency traders) who can buy / sell shares by the 100s of millions / billions in matter of seconds and pay just one commission. is it fair? especially because A o N is opened to the US traders but not to the canadians.
