Quote from SethArb:
are you experimenting with in Spot
mr gringinho ?
No, CME - short EuroFX 6E and long 6J USDJPY - essentially EURJPY

Also, margin requirements are 10% less on 6J when compared to 6E, but they both pay $ 12.50. If you play 1-lots, you should look into this kind of play - getting $25 on every EURJPY tick - with the same margin requirement. Needless to say - it's playing with fire considering slippage etc on rabid futures.

Right now, EURJPY is just above 134.55 which is trendline support which was breached earlier.
Just watch http://www.dailyfx.com/FinanceChart.html or something similar to see the EURJPY play.
