What exactly are ISI, BELZ, OES, etc.? Are they intermediaries between a firm and the exchange? Can't a firm just connect directly to SDOT, or do these provide some added value (other than being able to get multiple NX fills within the time window)?
Anyone know who Assent uses? My only route to NYSE/AMEX just says SDOT, and I haven't been charged any fees in the past.
