You don't have to buy as much as you want. Futures are for sale. No one sells it, no one buys it. This is completely different from stocks. These stocks are available first and put on the stock market for you to buy and sell. Futures were not available at first. There are two copies of all contracts. More than one bite. Not bad at all. So it's impossible to have what you said later. If you watch too much, no one will pay the bill. Because you can't write many bills at all. Then there is no limit to the daily limit or the daily limit. There will always be a price in the end, and people will disagree, right? At this time, both sides can open positions again.

Therefore, in the stock market, there may be cases where everyone makes money on the books or everyone loses money. It is impossible in the futures market. Always make half and lose half. If you can look it up in the computer of the exchange, you can trace back to the source of each contract and find out who gave you the money you earned or who gave you the money you lost.
