As most of you already know, ECNs will sometimes bonify their rebates and reduce their fees when their client hits a certain volume threshold. Ex: ARCA : Greater than 30 million shares added and greater than 60 million shares total (added, removed, routed) in Tape ABC ... will get you a better rebate and cost you less to "take" My question is : How are these figures calculated ? Prop firm by prop firm ? Or by b/d ? Or clearing firm ? If Prop firm A and B and C all work with Penson for example, is the daily volume calculated from what goes through Penson as a whole or is each firm's volume taken on their own in the calculations ? Thanks
Whoever has the membership or agreement in place with that particular exchange/ecn. It just depends on what memberships your firm has vs. what Penson has. If they are using all of pensons memberships then they will be off pensons umbrella.
