Let's talk about the general situation first, and then Luo Shu, he is a little different. )

For example, suppose A buys goods from B, but has no cash (or doesn't want to trade in cash for the time being).

Two people talk about the price first, and B gives the goods to A. At the appointed time, A pays at the original agreed price.

There are two situations:

If the commodity price rises within the agreed time,

A buys at a price lower than the latest market price, and A makes money.

If the price is lowered,

B sells at a price higher than the latest market price, and B makes money.

Lawrence is a little different. Contrary to the general situation, he asked Amat to pay first and deliver the goods the next day.

Because Amar has a lot of pyrite in his handle, most of his capital is in this shipment.

Uncle Lawrence's greatest purpose is, of course, for Holo (nominally a duel)

But this is actually setting a trap for Amat.

Uncle, after reaching an agreement,

Immediately set about lowering the price of pyrite (manipulating the market), which caused Amat to suffer heavy losses after the agreed time.
