Someone here must swing, or has swung a decent line, yet no one cn answer my question......
here is an example, i go to send an arca market to hit 6k shares, the offer is 0.38(700 shares island), 0.39(1800 shares arca),
0.4(3500 shares ADFN), somehow i hit 700 arca and miss the rest, point is it will hit level 1 and miss everything else, obviously i dont consider myself a high roller just that i take on more shares than 90% of this board, wether that is good or bad should be another debate, but what can i do to hit all this without them dodging once i hit the L1 quote?
This is the one of the many things i hate about comps!!!
They generate a totally false L2 which they have no intention of ever taking on.
There is no nasdaq floor so how am i being consistently gamed?
NITRO?
Porn,
Some of the problem is a speed issue, but the real problem is that the NSDQ order matching system is extremely inefficient.
Even in super liquid stocks (DELL, INTC, etc.) I noticed that whenever I would swipe a out of a block (say 25k shares), even if there were multiple bids totaling 100k shares, I would often just get a partial fill and the order would reroute down to the next penny for the rest.
After months of me complaining to our tech staff they finally got to the bottom of the problem. It wasn't our platform or a speed routing issue, it's that the NSDQ system is set up in such a way that the bids/offers on the book are able to be pulled before their own internal system can hit them.
Here's an example...
NSDQ aggregated quote is showing 30,000 shares on the bid.
Those 30,000 shares are 5 different orders in this sequence..
100
1000
800
25000
3100
Assume all those orders were box programs with top tier speed...
If you sent an order for 30,000 shares, you would immediately get the 100 on top and probably the next 1000, but the 800, 25000, and 3100 would all be able to pull before the shitty NSDQ system can hit them (and forget about routing through ARCA or another ECN....that would be even slower).
How in the world this is allowed to happen is beyond comprehension.
Hope this helped. PM me if you have any other questions.
