The ticker thing has seemed to be inaccurate with these kind of things, what do the charts at bitcoinwisdom or bitcoinity say? Often the ticker will show a much lower low than any trade that actually went through...no idea why but it was already doing that many months ago before I stopped using them.
The charts from BitcoinWisdom show the dips below my buy order.. I learnt ages ago that the MtGox chart was useless. I messaged MtGox support about this yesterday and I see this morning my ticket is still awaiting assignment!!
I've since cancelled my buy order and will be transferring all my funds out to a *real* exchange..
What a steaming pile of ______!!!
