I have read a good bit about various command lines that can be modified for orders to various ecn's/exchanges which affect routing options, but have not seen any way to implement this in Realtick. Is it possible? In order to postnopref on nsdq, for example, I am still having to pref INET (not pref nsdq, it rejects it!). Is there a resource compiled with the various command switches for some or most ecn's/exchanges I can be pointed to? Also open to criticism of the realtick platform if that is an issue as well. Thanks,
