This was a technical trade, trying to trade the range. The price has broken out to the downside on EUR fiscal worries and JPY strength based on Chinese tightening and rising risk aversion. Perhaps one to short tomorrow.
Technical range trades have not gone well for me. The problem is that markets are fuzzy around the extremes of the range; if you have a wide stop to get around that, the risk-reward on the trade looks poor because the upside potential is limited by the size of the range.
