It's actually Monday night: I've been asked to check the WTI OIL and I found the task a bit hard.
After taking a bit dive to $35.50 from $147.50 in 2008, the commodity is sitting now at $92 which is exacly 50% of that range.
As you can see by the weekly chart below the WTI performed 3 waves up, reaching $115 (wave 3). Now the question is: why 3 waves only and not 5? A plausible explanation could be that it's now unfolding "major retracement wave 4" (out 5 waves up).
In its simplest espression, "major retracement wave 4" is a big zig-zag made of 3 to 5 retracement waves. The OIL so far performed 2 of those retracement waves and now it's trying to complete wave 3 down.
On its way down, it stopped on the most important support. Hence, it might bounce back for a while (rally) before resuming the downtrend and breakout the channel on the downside.
If this happens, the target could be $97-$98.5. Then down again to $80. Also, the channel was touched 4 times and this prelude to a bounce back (rally) usually followed by a breakout on the downside.
This could be confirmed by the 3 red candles down that usually indicate a bullish reversal formation named "the ladder bottom".
