On the 4-hour chart, we've spotted the divergence between the Stochastic Oscillator with the crude oil price. This fact indicates there is a possibility that the Exponential 21-period Moving Average will be tested by the close as its dynamic support will try to break out and close below 70.50 and will target the next support level at 68.50 (as long as the price does not break out and closes above the 72.82 level).
