Forgive my ignorance but could someone please clarify what pass through exchange fees are for those of us who are uninformed. Most of that stuff I dont understand since I am only familiar wth an all in bundled fee structure. Is it anythng to do with ECN passthroughs? That is what I would like to know. Those passthrough fees really add up and I would dearly love to cap my fees at 500 dollars a month. I suspect probably not but if anyone can tell us exactly what pass through exchange fees refers to Id like to know.
