IDK that much about the finer parts of trading, since I just approached it from a ML perspective.

eh, if you've got the money to be worrying about moving the market, you're using brokers' advanced execution algos and darkpools.

These aren't silver bullets. Both cost more, in fees, and have a habit of leaking order information across informal channels. They're also, generally, slower--there are, on average, fewer buyers and sellers for a given security in a dark pool than in the open market.
