Quote from walterjennings:
So let me get this straight. You are advocating the SEC force whoever sold those 3000 to take your worse bid and pay 60 cents more for the trade to make it 'fair'?
If someone wants to undercut you, they should be allowed. Otherwise you are no longer dealing with a free market.
That being said. You should be allowed to bid anything you want, including 3.1699, you should do some research into ECNs and figure out who allows it.
YOU HIT THE NAIL ON THE HEAD and you are 1000% percent right with that statement.
BUT that is NOT how it is working with HFT. They are NOT bidding or offering inside the market, they DO NOT decide they want to bid higher than you are sell stock cheaper than you UNTIL the order they are reacting with is coming in.
Have you EVER seen a stock over $1.00 quoted in sub-pennys???? NO NO NO NO
Do you know why?????
Because it is illegal that's why
SO answer me this, if you cannot quote in sub - penny increments, and the sell order I electronically enter get executed in milliseconds, how exactly is someone who cannot have a quote in between the market reacting to my sell order and micro penny improving the market????
BY HAVING A " FIRST LOOK" at the order flow!!!!!!
The NYSE had this until a yr ago when the SEC made them take it out of the system.
FIRST LOOK, means that your trading ALGO is LIVING inside the brain of the system, residing between the clearing house and/or orderflow pipes and getting a look at the order before it actually hits the published bids/offers it is intended to.
So the order coming in is being diverted from it's original destination ( i.e. the 3.19 bid you intended to hit) and it is being bought at 3.1901, with a whopping .001 of risk, and then sold .001 better than the published offer, all the while collecting .35 per 100 share LIQUIDITY rebate!!! WOnderful game isn't it.
The people who completely MISS THE POINT and say that the few pennys don't matter need to take their head out of their asses. It's not about penny's, nor is it about the spead..
HFT TRADING GOAL = NET ZERO TRADING
Wash all trades for even money all the while collecting REBATES!!!
TOLL COLLECTING WITH ZERO RISK
THAT IS HOW HFT GO 4 YRS without a losing day
HOW EXACTLY do you get your orderflow to reside within the realm between the orderflow entry pipes and the orders they are meant to interact with?????????
BY KICKING BACK TO THE CLEARING HOUSES!!!!
That one for another time
Have a nice day, try to defend that one, it's about time the public knows what really goes on
