"What does that mean? Are they going to halt trading? TIA."
No, they won't halt trading in general, although some brokerages, particularly the ones that clear through Penson might only allow you to sell now, rather than buy. Zecco are often quoted as refusing to deal in chilled penny stocks.
Other brokerages may now charge much higher transaction fees - in some cases several hundred dollars. This is because trade-for-trade dealing is much more difficult - and therefore expensive - to arrange.
With some other brokers currently it doesn't make any difference - I've heard that you can trade such stocks through Scottrade and TDA without difficulty or extra cost. I've alos heard that all brokerages will move to refuse to deal with such stocks in time, but I have no idea if that is true or not.
Finally, you will get a lot more FTDs reported on MILV. As the bimonthly figures will show, these will not represent short interest, but just the difficulty in settling trades for stocks that are DTC chilled.
Hope this helps.
BTW, the DTC chill is DTCC's way of saying "CAVEAT EMPTOR!"
