The 28 level for WTI Crude is going to be vulnerable. When we look at the 4H chart, we can see that crude went through a period of consolidation. The consolidation structure is essentially a head and shoulders pattern, which is a bearish signal when it is found in the middle of a downtrend.USDWTI 4H Chart 2/10(click to enlarge)A couple more technical notes:1) Price held under the 200-period simple moving average. The bearish bias remains even in the intra-day, 4H chart.2) In February, the RSI dipped to 30, then rebounded but held under 60. It is again pushing below 30. This dynamic reflects the fact that bearish momentum has been re-established. It is quite possible price is going down to 20. The range of the consolidation was roughly 28-35 = 7. 28-7 = 21. So, when we project the range of the consolidation downwards, we would target the 20-21 area. We should also look at the 29-30 area as former support turned into possible resistance during this decline towards 20-21.Get ready for the slide. Best to avoid FCX, USO and anything oil related for now.
