How late can an out of market fill be broken? Does it depend on the ECN? Is it possible for a trade to be broken the next trading day? thanks,
nothing should be able to be broken the next day.... that's total BS. ARCA/INET usually require the erroneous trade to be reported within 30 or so minutes. But they can take a couple hours to be actually broken (depends if it goes to ruling, appeals etc...) mnx
