huge limits on the market depth

look at the sell limit side of the market depth. this can generally mean two things
1. manipulation of the market makers - as the price moves towards them, they will disappear and the price runs up to find buy-stop orders of sellers (stoprun)
2. fond´s/bank´s sell offer - these are real and as the market will fill them all and find no interest on upper prices, it falls afterwards

here the case no 2. happened
