Brent oil is having a tough time.For 40 weeks now, Brent quotes cannot or do not want to leave the corridor between the levels of 70.83-86.32. And it looks like now the decline is possible to the lower limit. The nearest level that can provide resistance now is 84.40. I propose to pay attention to it, and after the breakdown, it is very likely that we will get the opportunity to open a sale.
