Quote from ak15:
...IB keeps adding a penny before posting in order to add to liquidity and earn itself rebates.
1. Is the significance of this for situations that you place a big bid i.e. that with IB it's never "noticed" in the market? --while with another broker, it would first get "noticed"?
[Keep a close eye on Timber Hill their MM particularly when you place large orders. He will keep posting large size in the opposite direction of your trade. However, when he reaches the inside bid or ask he will back away to a few levels down.
2. It would be interesting to know if you would suddenly cancel your buy order and place an offer, would Timber Hill suddenly flip their position as well? Or if it may all depend on if they are net short or net long?
3. It seems I have witnessed the same syndrom happen, but have not known who is the counterparty doing this. How could one verify if it's Timber Hill, or if it's simply the shorts?
4. If IB is net short and their objective is to "contain" the stock price, are IB customers affected by this more than other retail traders?
He will keep repeating this process over and over again thereby sending a message to other MMs.
5. If this activity is monitored by another MM, is your point that it may become like the "sharks" seeing "blood" & they come and join?
