Abstract
We show that externally-verifiable characteristics (inexpensive for a third-party to verify) of traders or orders allow pro"table purchasing of order flow and internalization. We introduce total trading cost, defined as the effective half spread plus the broker's per share commission, as a measure of execution quality. We use this measure to reinterpret prior empirical studies of: (1) execution quality across trading venues and (2) cream-skimming by purchasers of order flow. Finally, we show brokers can use their direct relationships with customers to assess internally-verifiable characteristics (inexpensive for direct verification) in order to increase profits extracted from customer orders.
