Generally odd lot - otherwise everything eventually will print. If not an exchange then upon a TRF, but still hits the tape. FINRA has a time limit to report.
Are you sure this makes sense? I already know td order flow gets routed to hft firms like citadel, virtu, etc.. But its an executed trade lol. its in time and sales.
As a side note, its the best fill in that 3 or 4 minute time span. So perhaps this price improvement that is advertised is real, although it was a limit order so idk. Went to citadel btw..
What was your order ? A limit to buy 15 @ 117.92 ? Limit orders aren’t shown on the T&S We can see selling happening at your price, These sellers are the ones that filled your limit. If you want your order to be displayed on the tape, You need to execute market (triggering) orders.
