As far as I understand, if you are betting on the daily future it will close automatically at the end of the day but based on the November future price not the spot price.
If you are betting on the actual November future contract then it will close on the expiry day in November based on the futures price. If it is a spread bet then it is cash settled meaning it will automatically close at the settlement price at expiry and your account will be credited or debited according to your position profit/loss.
