Look back at the volume. A boatload was sold at 0001. Those have to be taken out, bought off the market {by someone} before we move to the 0002s and higher...
Your "test sell" as you put it at .0001 probably will not go through until the mm's get off the ask at .0001! They do not like competition and usually don't buy from you at .0001 until they up the ask to .0002 & then will buy yours from you once they have a buyer for them at 2! It's not like you "queue" yourself in line, they can sell all day long without touching yours!
