The range is formed by the 14.6 percent and the 7 percent retracements of the uptrend from $42.36 to $57.88. A break above $56.79 could lead to a gain to $57.88, while a break below $55.61 could cause a loss to $54.22.

The bias could be towards the downside, as oil failed twice to break a resistance at $57.93, the 50 percent projection level of an upward wave C from $51.23. These failures suggest the formation of a double-top, which is a trend reversal pattern.

The pattern will be confirmed when oil falls below its Feb. 26 low of $55.02. It indicates a target around $51.95. On the daily chart, a retracement analysis on a medium-term uptrend from $26.05 to $76.90 reveals a key resistance at $57.48, the 38.2 percent level.

Given that oil failed twice to break $57.48, it may remain below this level for a few days or retrace towards $51.48.
