GNCP - Immediate fill by CDEL today, with immediate reporting to the L2 quoting system. No delay in reporting...No "seq" trades...
The "seq" and the delays in reporting only happen when there is a consorted effort to close the PPS at $0.000001 after a $0.000001 trade, no matter how many buys at $0.0001 happen thereafter.
Keeping track of which MM's fill those "seq" trades immediately on the client/broker side, but delay the reporting in order to "justify" a "seq" trade...
