that's usually how it goes. historically, stocks returning on the grey market following a suspension lose 50 to 80 % the first day. it usually goes downhill after thet with volume drying up and people unable to sell at any price.
No no mad dash trading is limited on the Greys to match buy and sell and you can only trade through your broker. No MM's brokers have to match a seller with a buyer and that is the bottle neck no buyers!!!
