A break above $64.62, however, could confirm the progress of the wave c towards $65.56. This resistance at $64.62 is not working alone, it is strengthened by another one at $64.90 on the daily chart, the 23.6 percent retracement on the uptrend from $26.05 to $76.90.

Either the uptrend from the Dec. 24, 2018 low of $42.36 is peaking, or the correction triggered by the resistance at $64.90 is extending. In either case, oil is expected to slide more.

The correction may consist of three waves. The third wave labelled c is unfolding. It will be too aggressive to target $57.48, a realistic target could be the April 15 low of $63.03.
