Saudi Aramco Base Oil Company is trading within a potential broadening wedge formation, with both the lower and upper ascending trendlines supporting the price. The immediate support zone represents an optimal buying area before the price advances towards the targeted 180 level. Short term approach can be consider initially around 152-153 and secondary approach around 165. The internal demand zone is identified around 143 as a favorable accumulation point. On the flip side, if the trend line breaks then more bearish momentum can be seen. Use stop loss below 140 to manage risk.
