I have made a limit order to buy MASC (sells OTC) at 1.76. That price is higher than what online systems are saying is the current bid is. This was done early this week yet the highest bid shown is 1.71. (It's a very thinly traded stock so it this doesn't change much). I contacted my discount broker who confirmed that the order has been sent and says that "it sometimes happens that bids don't appear". Is this true? Sounds odd to me. How would a potential seller know that there is a better bid out there if it's not shown?
