Did you even read the book? The entire point is that some HFTs are given priority fills on orders that no one else has access to, even when the HFT quotes are worse, in return for kickbacks to the exchanges.
- NkVczPkybiXICG 13y agoEveryone on that exchange has the same access to the same types of orders. HFTs only get priority if someone gives them priority. If these order types are so powerful, why aren't everyone using them? Also, I will reiterate: HFTs NEVER get fills on quotes that are worse than any other participant on the same exchange. That violates RegNMS, and is straight up illegal.
- asdfologist 13y agoFalse - HFT firms have access to special order types. Example is Hide Not Slide, which is mentioned in the book and also here [0]. [0] http://online.wsj.com/news/articles/SB10000872396390443989204577599243693561670 http://online.wsj.com/news/articles/SB1000087239639044398920...
- consz 13y agoWhy do you believe only HFTs have access to hide not slide? That order type is plainly listed on DirectEdge's website, e.g. https://www.directedge.com/Portals/0/01Trading/Trading%20Products/Order%20Types/Order%20Type%20Guide.pdf https://www.directedge.com/Portals/0/01Trading/Trading%20Pro...

- NkVczPkybiXICG 13y agoWhen the orders were added, there was a modification to the FIX specification for the exchange. For example: http://www.directedge.com/Portals/0/docs/Direct%20Edge%20Next%20Gen%20FIX%20Manual.pdf http://www.directedge.com/Portals/0/docs/Direct%20Edge%20Nex.... It is everyone who trades on that exchange's responsibility to stay up to date with what's available, and how it interacts with their trading strategy. "concealed", in this context, just means "too lazy to carefully read the documentation".
- fr0sty 13y agoany exchange member may submit a hide-not-slide order. there is nothing secret about them.
- asdfologist 13y agoThey were originally concealed.
- doktrin 13y ago> If these order types are so powerful, why aren't everyone using them? An allegation made in Dark Pools was that the existence of the order types was initially deliberately concealed from most actors in the market. The claim was well substantiated, from what I could tell.
