it would be known that if you put your BID is with "ALL OR NONE" then it will not show up on L2. It's what some that understand how this stuff works would call a hidden BID
Please sell some of your shares to the BID and find out for yourself what I am saying is true
If you don't pick "ALL OR NONE" when you place your BID you risk the chance of get hit by a tiny paint down fill. You still have to pay your broker fees even if you only get 1 share on that fill. I got tired of paying $8 every day for all the tiny 100 share fills I was getting.
All IMO. You should NEVER make ANY financial decisions based on my opinion. You should pretty much always do the opposite. I do this for fun. Losing money is NO FUN! Please do your own DD
