Hi, I set up recurring purchases of SPY and VTI on Robinhood a few months ago. I noticed that I was getting pretty crappy fills almost every order. I chatted with support last night and they stated that since I wasn't buying in even lots of 100 shares, they had to fill my order by purchasing odd lots. I'm assuming there's a market premium that they charge for purchasing odd lots. Is it like this for all brokers when setting up recurring purchases? Thanks.
