The contract is riding on a wave C from $60.60. This wave could travel into a wide range of $68.77-$73.82, formed by its 61.8 percent and the 100 percent projection levels.

The resistance at $67.21 has been more or less broken. The next resistance will be at $68.77. Support is fixed at the Feb. 21 low of $66.69, a break below which could cause a loss to $65.65.

It must be noted that the wave C could end around either $68.77 or $73.82. As a result, the resistance at $68.77 may trigger a decent correction, which has not occurred ever since the wave C started.

Making such a correction more likely is another resistance at $68.33 on the daily chart, the 50 percent retracement on the downtrend from $86.74 to $49.93.

The pattern from the Nov. 29, 2018 low of $57.50 looks like an inverted head-and-shoulders. Even though it suggests a target around $78.05, a pullback towards its neckline around $64 has not been observed. This pullback may develop around $68.33.
