And if this order is not being pulled out by the owner, can it be eaten in pieces or will a potential buyer need to fullfill this order in total?
In pieces, could take hours, or minutes... depending on the dump and pump whales

So basically, if the owners intention is to really sell at this price, he'd be better off slicing the order up into pieces making each piece more expensive to gain more profit? but since he didn't to that this can be flagged as an on purposely-set-wall to keep the price under 300 btc?
