I was commenting on your post to Zeev, "I got out of a situation like that by having my broker put in a "not held" order (their suggestion). They take the entire order you want to sell, but they somehow don't show the quantity for the ask."
At TradeStation it is routinely available and is called an Iceberg order, I suppose because all that one sees is the tip, while the bulk is hidden beneath the waves.
So, I answered your question, now it's your turn (LOL): what about NEM, 3-gap play?
