The bullish slant has been broken and gave us a buy signal. Then, the resistance at 0.7198 has been reached. We will now advise to trade only long positions as far as the slant is support. The break out of 0.7198 will give a new buy signal. However, the bullish potential will be limited given the fact that the upper band of the bearish channel is close. But, the break out of this line will give a strong buy signal.
