When market makers are buying/selling on the inside bid/ask, are they required to use their MM ID on one side or can they do it through INCA,ADFN, ARCA etc. on both sides completely anonymously?
e.g. GSCO buys through INCA on best bid and sells using ADFN on the best ask whilst his GSCO ID is displayed nowhere near the inside.
Also, what's the list of ECNs market makers can use to buy/sell.
Thanks
