$ACE When the price was low, I already bought the spot, so when the price goes up, I’ll sell gradually. When it reaches a high enough price, I’ll enter a futures position. If the price rises, I’ll sell the spot; if the price drops, I’ll profit from the futures. As for this kind of order book, it can’t possibly be pushed up to 0.5, 0.8, or $1 within a single day. If I enter a long futures position and the price keeps rising, then usually when it drops, it also has to pass through my futures entry level—so I’ll be safe. For long futures, it’s just harder to swallow.
