It's been asked, so I'll add that one account gained 880% [5.1K to 45K+] on initial balance for the four month period. They were trading the mis-pricing w/o hedge. The edge was North of 25bp on 3-4 day bets, when discovered.
A decade later: Oanda was pricing touches as digitals and blamed Dodd-Frank for killing Box Options. In fact we hit them for ~$120K that day. Dodd nor Frank were trading Box Options on EUR/JPY that day.
