I just received an email from Cybertrader that states: "Please be aware that the NYSE & AMEX prohibit the unbundling of ARCA/NYSE/AMEX Listed round lots for the purpose of entering odd-lots. This notification is to inform you that your account xxxxxxxx exhibited this behavior on 08/01/2007. We understand you may not have been aware of these regulations. However, should this type of trading activity continue, your account may be subject to order-entry restriction to ensure compliance with exchange rules." I called Cybertrader and asked them what this means...and they simply stated that the exchanges didn't like me buying/selling in odd-lots and complained to Cybertrader about it. The representative said that it was a pain in the ass to deal with odd-lots and so they didn't want to have to deal with it. I think it's ridiculous, since most orders are matched electronically anyways...and I almost always rout my orders through the ECNs (ARCA or Instinet (NSDQ)) what difference could it make to take my order? Also...I've been trading the same way for years...only using odd-lots with high-priced stocks ala GOOG, what did I do to suddenly trigger such a warning? Is this a new rule? Anyone else get this warning before?
