I have a question, hope it can be answered as currently it’s baffling me. I have long positions in NatGas which I’ve held for a while now. Nothing marginalising but having seen the recent drops I opened my account after a good month of not looking. To my surprise my position was still clearly fine within a safe margin but my equity had gained £800. Usually longs cost fees to hold overnight so was shocked to see this. I phoned my broker and they said it was due to the disparity against futures price and cash value provided by there market price, the difference they provide a credit to my account. Based on if this variance stays the same (probably won’t) I’d gain 9600ish for the year but by holding my position. It feels like a cheat code but want to know if anyone has encountered the same?
