Futures contract exchanges are bound to leave gaps because of price differences, which can be replaced by contract indexes from the perspective of technical analysis.
There is nothing you can do about it. That's just the price shown in the chart. If you want to invest for a long time, you need to choose a forward contract to open a position, and then you can hold it for a long time. If you do it month by month, you need to change the month. There is something wrong with the quotation system.
In general, the forward price is higher than the recent one, because the farther the storage and normal loss are, the higher the price is.
