Yesterday at 11:45 Middle european time I noticed that the orderbook deapth of the bid side was very low. So i decided to place a couple of very low offers there. When i placed my first order of 2000 LTC @ 1$ it got executed within minutes and I saw the USD being deducted and the LTC added to my account. Everything fine so far. The order number of this is the following:
TXID: 4269089 2000LTC Executed @ 1.0(2000.0)
After this i placed another order at 1.5$ for another 2000 LTC. This order too was Executed within minutes and added to my account, the 3000$ were deducted immediately too. Everything looked right then.
TXID: 4269124 2000LTC Executed @ 1.5(2000.0)
You should not have been able to buy LTC at $1 each.
If this was caused by a software glitch at Bitfinex then it is reasonable for them to void the transactions - that is what NYSE and NASDAQ and any other exchange do.
Then you clearly have no idea what happend yesterday at bitfinex... It is not my problem that the traders that used leveraged positions got a margin call and had to sell everything with a huge loss...
