How does Oil Club work?

The "Oil Manger" creates a new oil buy with a close date (usually in a week's time).  Everyone who has the site role of "Oil User" is sent an email to tell them about the new oil buy.  Those that want oil login and place an order before the oil buy close date.

UPDATE

With current situation with the Ukraine War leading to rapid changes in oil price then ordering is now shortened so the window to be caught in a price surge is reduced.  Orders are open Mon-Wed (maybe Sat/Sun-Wed).  Boilerjuice price is checked to set a benchmark and a limit over which the order is abandoned.  So if boilerjuice is offering oil at 80p then a safety cutoff of 90p is set (BJ+10p).  If the oil price rises during the open buy above this cutoff then the order is abandoned.  This would be on a Thursday so allows those who must have oil to place their orders direct with other companies or in time for Boilerjuice's buying weekend (Fri-Sun).
