Just realized the example was wrong, I'm so use to showing how a buy order is passed. Yours was a sell and you changed your order before your original order was reached. But I hope everyone gets the idea. Every time you move your order, you get at the back of the new line. Buying or selling.
I often say if you make your mind up to change your mind, in a fast moving stock, put it a couple clicks above ask or below bid. You did this, but it was so fast you still didn't close.
