Si Yang, I think you might want to stick with your previous idea that price ceiling of crude will more likely around 43. REASON: 1. Fib retracement (0.618 point) of last the downfall shows this retrace might not higher than 43.5; 2. 43.15 area will be considered as a resistance; 3. The momentum and 4hr rsi wont support this as high as 44.4;
Best luck on your trading.
