when orders are sent from broker to market makers or to the nasdaq what info is sent?

A fact. And besides that, MM don't care about the identity behind the Public Customer orders.

 

a fact that you got from where? and how u know they dont care?

 

I'm not here to convince anybody.
In a place like here, you have to separate the wheat from the chaff.

 

@Overnight , it’s not about being paranoid or about complaining, it’s about fairness and transparency. I don’t know for a fact what, if any, info is shared, but I know for a fact that if your flow is toxic, your orders will be eventually segregated. Of course if you are using your friendly retail broker, your orders will not be toxic by design. Talking strictly US equities, but pretty sure options even worse.

 

what is a toxic flow?

 

please leave this post and dont comment.. i am not interested in your answers ... you are being toxic

 

OP is talking about private info being gleaned from an order placed and executed at a broker, that market-makers will somehow exploit. I do not agree with that theory. I believe that is unfounded paranoia.

 

ok u said what u think from the first hour i posted the thread... now i want to know from someone who has some kind of proof... like some pdf of the api that is the brokers use to send to market maker... or some interview with someone... i am not intersted in what u think ... so please just leave this thread... maybe u just like to post stuff to get more post count and likes for some kind of benefit.. i dont care ... just stop commenting on my post... or i will report u for attacking me twice

 

Basically orders which make it hard for MMs to make money on. MMs still have best execution obligations and don’t want to trade against someone with some advantage be it informational or technological. They want all “dumb” money, none “smart” money.

 

interesting... how do you know this? i want to read more about this
