Sometimes my trading acct uses UBSS, most of the time they use NITE. I placed my order, they routed to NITE - if they would have routed to UBSS, They would have moved from $.07 to $.08 on the bid. Thus, making it look like a bigger wall.
I did it to provide strength in the bid. I have a decent amount of shares. I'm ok with adding 5,000-10,000 here and there. But if I can make that bid hold for a week or two then I can "afford to buy it more". If I buy it today I can't hypothecate that money elsewhere. So, if I get it today, im okay with it. If it sits there unfilled I'm okay with it. At least I know by bidding I'm making it look better, which in turn only helps the shares that I have already accumulated.
I see this going into the $.30s on the right momentum and news.
