Sorry but the OP is a "Joker broker". You know the type of broker that says "I have a client wanting to buy 10m barrels of Crude/Mazut/D2/JP1 at spot price with letter of credit from HSBC" 🙄.
Better still this video explains clearly what a joker broker is. Spot the signs early 😉. Trust me this is how the conversation will go as it always does smi(&%.
