Technical analysis of crude oil: Crude oil staged a fierce roller coaster yesterday, with short-term repeated tugs of war91.0Falling under pressure on the first line86.23On the first line, the market regained its lost ground after a strong recovery in the late trading session, returning to the downside and closing at a high level, which is equivalent to a day of losses and recovering all the lost ground. The fluctuation base is large, and the sawing range is also relatively large, which is in line with yesterday's range. It's just a short ride out of the roller coaster. The daily trend once again bottomed down and rebounded at the closing cross, and the second bottoming and rebound enabled the short-term structure to break out of the double needle bottoming trend of bottoming and rebounding. The competition between long and short shows intense intensity. 4The hour chart is lowered to the lower track of Bollinger Road and stabilized before confirming the resistance of the downward channel through reverse pumping. The short line is in a sawing vibration and there is support underneath86.0-86.30.There is resistance on the trend line, and the short term is seeking breakthroughs. Yesterday's repeated tug of war also showed intense competition between the long and short sides. Currently, considering4小时布林道收口当中,日内短线暂时先在布林道上下轨之间做震荡,后市留意区间破位再决定方向的延续,未破之前,靠近上轨先空,靠近下轨短多,短线不排除来回拉锯持续的走法。综合来看,原油今日短线操作思路上建议以回踩低多为主,反弹高空为辅,上方短期重点关注94.5-95.0Frontline resistance, short-term focus below92.0-91.5Frontline support.
