The following case is a special case, maybe just a case. I can't completely answer the question asked by the landlord, but I just provide a train of thought, because I do a lot of cash and little futures. Don't blame me for misspelling the terminology. . .
As can be seen from the second question, if someone buys it, someone will sell it. If no one sells it, no one will buy it. Capacity should be limited. Finally, even if it is delivered, it is decided by a few parties, not how much gold an aircraft carrier can sell. Moreover, this situation is also extreme. It is said that the daily turnover of the foreign exchange market is equivalent to one year's GDP in Germany, but this has never happened.
Suppose the current price of a mini gold futures market is ￥200/g, and the minimum trading unit is1g. Regardless of the handling fee and deposit, you can go long or short.
Start telling this story, again, just a special case.
There are only six rational traders in this market. Is it small enough?
A, B, C, look, there are 200,20/kloc-0,202 in each hand, that's all.
D E F bears also have 200,201202.
A buy 1g pending order ￥200 D short is also 200, so the current price is 200, D has empty orders, and A has multiple orders.
Similarly, when B and E enter, the price rises to 20 1. At this time, D has no stop loss and continues to hold empty orders. In the same way, A did not open a position.
Just when C and F hesitated, G suddenly entered this market. Unfortunately, G has 202,000.
Moreover, G was short, and an empty order of 202 yuan was hung up, and the hungry C took the order.
The price reached 202 yuan, up by 1%.
At this time, F is not bearish, but bullish, and D and E stop losses, so there are three 202 orders in the market (flat looks the same as buying-_-! ! )
G continue to be empty, accompany to the end, and take over everything.
therefore
More than 200 bills
B ￥ 2,065,438+0 orders
202 yuan more than a bill
D short position ￥ 199 cash
E short position of $200 in cash.
202 forint multi-order
G in short, there are many empty orders
D, e flips more, killing your eyes!
Two people bought it at the current price of 202 yuan, or maybe they wanted to take advantage of it and signed a bill of 2065438 yuan +0.
Then it's settled.
Now the price has become 20 1. The previous six people were all multiple orders, G was six empty orders, and everyone was Man Cang.
That's what the landlord said All the long money is used up, and the short money is still thrown in.
At this time, there is a problem: if A to F are all dead bulls and don't sell until the new high of 203 yuan, then the price is fixed at 20 1. Even if G is sold, no one has the money to buy it, and G can't finally close the position and make a profit.
