You can buy shares on uncleared funds, you just cannot resell them without causing a free ride. Even free rides only mean that you might get a suspension on trading with margin or uncleared funds.
MM's have Level 3 so they can see where the stop losses are and manipulate the price to trigger them. Sorry to hear this happened to you. If the ticker change doesn't hit until the 7th or 8th as others have proposed, you may be ok.
