Risktaker, you're reading way too much zero hedge to be healthy. Cut back man.
This is simply bullshit!Quote from risktaker:
Because they cancel their fake bids/offers and run like hell as soon as there are real orders hitting them, that's why. Their posted volumes are mostly fake.
Quote from nebulous:
And for anyone that doubts HFT adds liquidiy - watch what happens to the market when a major data provider goes down - think it was in June when the major cdn data provider crashed and the spreads opened up to 10x average with negligable volume for the entire .5 hour they were down. Considering there is very little investor activity in the market right now, the volume you see is mainly algo and prop, possibly a testiment to how much liquidity they do add.

There is no such thing as fake quote. If they are able to react to market changes faster then you are, that just means that you are slow.
Also, if you think that this liquidity is fake and it will get canceled, go ahead and start providing a real liquidity.
Look, if you see 50K shares at the bid, and you send one order at this price it will fill. If not, something is wrong with your infrastructure.Quote from Bob111:
as i said before-i see this "bullshit" every single day,when i unload large basket of stocks at the current bids. you can try this too. at any time during regular hours-calculate the spread between bid and ask then-sell 100 different stocks with average volume 50-250K at the bid and see what happens. spread will immediately change,you going to receive few fills ans lots of 1-2 shares partial fills and many of them will either back away from current bids OR someone else will step in and pick those orders and YOU will end up with nothing. i'm talking about simple situation,where 100 shares at $10 is displayed and you buy those 100 shares, not 10000 shares.
