PLATTS WINDOW * Indications are free on board (FOB) unless marked as cost, insurance and freight (CIF) or delivered at place (DAP). * There were two deals, a trade source said. * Forties: Vitol bought November 6-8 from BP at cash BFOE December plus $1.20 on a FOB Basis Hound Point. That equalled to dated Brent plus $1.63, according to Reuters calculations. That was up from the last deal at dated Brent plus $1.20 last week. * DUC: BP bought a cargo from TotalEnergies October 18-20 at dated Brent minus 50 cents FOB Fredericia.
