Read that in another forum: "I want to add the following observation. The WTI or Brent prices unlikely to go past $51.42 due to the fact that the high price above $51 will encourage the Shale Oil Rigs to be setup to produce Shale Oil that the Opec will want to see Shale Producers go bankrupt. It cost about $50 to produce a barrel of Shale oil but the Opec people can pump the crude oil at about $23. a barrel. This is not to say it definitely will not go up but any higher price is usually short live. This range will give us a lot of trades. The Saudis are very poor too as they cannot pay a lot of their business partners."
