Yeah, that's why I said in the extreme case you have to participate in all the volume. Of course randomly trading doesn't prove that you achieve VWAP, but I'm just saying that it's probably not terribly far off.
- fr0sty 15y agoAnd how far is "not terribly far"? Pennies? Nickles? Dimes? Dollars? I can say with a great deal of confidence that a "random" VWAP algorithm would, on average, suck.
- joncooper 15y agoFor context: Many brokers will guarantee an execution at VWAP. It's a competitive business. The last time I put in such an order, I traded a double-digit percentage of the day's volume and paid 10bp commission (0.10%).
- fr0sty 15y agoBrokers guarantee VWAP only if they also are paid a very healthy commission. They generally lose to VWAP, but makeup for it in premiums. Plus, if you are dealing with a large broker they may just cross your order with an offsetting order (or their own position, execute nothing in the market and keep the entire premium.
