Quote from atticus:
Sure Barry. I assume you meant "arbitrage" but this trade doesn't qualify. I am long the 152/160 DNT and long ES hedge as a proxy. The hedge is sized to lose no more than 20% of the exposure taken on the DNT under 2 sigmas on ES/SPX. I can take heat on ES down to 1290 before I take a loss of 20% of the notional exposure on the EURJPY exotic. So my hard-stop is at 1290.
The 900% return was the result of a modeling error at Oanda. It's no longer exploitable and that 900% was the result on trading short gamma European binary range trades, unhedged. The hedged accounts did ~300% over four months.
