Technical analysis:

Crude Oil did setup perfect bull flag of the middle Bollinger band, which is good sign for the further upside movement. I expect further upside movement towards the levels at 52.50 and 54.30.

Buying the dips on 1h-4H seems like great strategy according to the current condition.

MACD oscillator did show big decreasing in momentum to the downside in the background and bull divergence, which is confirmation for our long bias.

Resistance levels are set at 52.20 and 52.50

Short-term support levelis set at 50.80
