The daily chart of the Crude Oil (WTI) shows a bullish trend in the last 6 months that has good chances to resume if the $104.00 support will hold.
The stochastic oscillator signaled good buying opportunities when it crossed below the oversold border (at 30) while is evolved for longer periods in the overbought areas, typical for a bullish trend.
The month of March formed a bearish channel that is, the most probable, a corrective move for the up-trend. However, if the stochastic oscillator is to be considered, than the buyers should initiate their positions when the fast %D brakes below the 30 level.
