For any Tradestation users: In time & sales window, the default color coding for trades is green for at (or above) ask, orange for at (or below) bid, but it claims WHITE is for "between bid and ask", which might make sense in some cases, but I see this constantly on LARGE (>50) lots in the YM, where the spread between bid & ask is 1 tick, so this is IMPOSSIBLE. Can anyone tell me what the WHITE trades signify? Very puzzled. Thanks in advance. W
