Just getting a bit more info here, so hopefully, someone can help. I've always used ARCA, INET, SDOT, Direct+, etc for routing, using mostly Limits. In experimenting with some very new ideas, I'm looking at other routing possibilities. A helpful member here (thanks, K!) alerted me to BATS, which, unless I misunderstand, just recently got exchange status. Anyone hae any experience routing to NITE and CSFB? Are fills and liquidity adequate, or only on highly-trade stocks? Any other routing possiblities worth looking at? I'm looking for places to execute more thinly-traded, high volatility stocks, but NOT BB or real cheap stuff. Thanks for any help!
