FXStreet (Córdoba) - Crude oil prices failed to sustain early gains and settled lower on Monday as growing tension between Saudi Arabia and Iran triggered volatility across markets. West Texas Intermediate crude for February lost 0.8% to settle at $36.76 a barrel on the New York Mercantile Exchange, after oscillating between a high of $38.39 and a low of $36.33. WTI technical view “Technically speaking, the daily chart shows that the price is now a few cents below a flat 20 SMA, while the Momentum indicator maintains a neutral stance, flat around its 100 level. The RSI indicator however, heads south, now around 43, anticipating some further declines”, said Valeria Bednarik, chief analyst at FXStreet. “In the shorter term and according to the 4 hours chart, the downside is also favored as the price failed to establish itself above the 20 and 100 SMAs, while the technical indicators head slightly lower around their mid-lines”.
