1.6670 is currently broken and a return on 1.66 is expected. The parity is moving in a big bullish channel and the lower band could give support to the price if the current movement continue. We will however advise to trade only long positions as far as the parity is into its channel. We will wait a reversal on 1.66 or on the lower band to enter long. However, if an exit of the channel occur, this will give a sell signal.
