The US dollar surged after consumer prices rose faster than expected last month. The euro’s rally came to a halt in the supply zone around 1.0190, then a fall below 1.0090 forced leveraged short-term long positions to close out. After the RSI sank into oversold territory, some traders could be tempted to buy the dip between 0.9950 and the parity level. 0.9870 is a critical floor and its breach would invalidate the current rebound and send the single currency below 0.9800. On the upside, 1.0090 has turned into a resistance.
