no dark pools report to cboe for equities. they have 90 secs to print.

no, sorry, ioi's aren't just 'pre-arranged' trading by another name. the reason: pre-arranged trades involve zero competition. ioi's, however,...
when YOU send the order YOU are "flashing" it to the darkpool (assuming it accepts IOI's). the darkpool doesn't "flash" anything. it's a choice...
