Wouldn't worry ...since bid at .0009 and ask @ .0011 you were filled in the middle, was not a large purchase ...so take it as a good purchase!...can't beat these prices right now...wish I had dry powder ...I can't express how I would love to pick more up...but timing is everything!...and I have things to take care of!
Your brokerage, if they are worth their salt, will always get a lower price for you, when they can...totally normal and a great surprise when you are expecting to pay more...
