For exchanges that support hidden limit orders is there ever a reasin not to use them? Why would I show a visible limit if I can do a hidden instead?
The visible display size theoretically gets priority over hidden, but with the explosion of so many new order types at the request of HFT, maybe that's not true anymore?
I'd like to see a discussion of all the new order types. It's quite vexing with so many exchanges and the various broker implementations of them.
yep..hidden order have no priority whatsoever. and anyone can trade thru it on other exchanges. right now it's doesn't really matter ,if you are retail trader. specially when you right about price direction in short time frame. you hide your order-lose priority(no fill),you show it-you will be screwed by subpenny HTF at your price(no fill).
i am referring to the specific orders. every exchange calls them something different and treats them differently. You provided no info; why did you even post
