1. Futures are mainly not commodities, but standardized tradable contracts with certain mass products such as cotton, soybeans, oil and financial assets such as stocks and bonds as the subject matter. Therefore, the subject matter can be commodities (such as gold, crude oil and agricultural products) or financial instruments. The delivery date of futures can be one week later, one month later, three months later or even one year later.

2. The reasons for locking the warehouse are as follows:

The locked position means the closed position. After locking the position, the amount in the account will not change.

For example, at the price of 1700, we bought and sold primary gold at the same time (ignoring the price difference), and the price of gold rose to 1770, with a profit of 700 points and a profit of 7000 dollars. Empty orders lost 700 points and lost 7000 dollars. This account is very simple. Locking positions equals closing positions.

(1) reason 1: the need for strategy.

For example, both quantitative strategies and hedging strategies in foreign exchange include lock-in transactions. In addition, there are related varieties of hedging, such as Brent crude oil and American crude oil long-short hedging in foreign exchange transactions; Or in futures trading, rebar and hot coil hedge each other, and the price difference of these price-linked varieties will return to value after amplification.

(2) The second reason for locking positions is to avoid the stop loss problem in trading.

"Floating losses are not losses", and losses are declining. Many traders get psychological comfort through such transactions. It's time to stop loss. If you don't stop loss, lock the position first. Although locking positions is essentially locking in losses, it is more acceptable from the heart.

What is a futures lock?

1. Locking a warehouse is a way to lock in profits or losses without losing warehouse receipts. Lock positions are widely used in the futures market because ordinary investors can enjoy the two-way operation of short selling.

2. Quick Lock means that when you select one of your positions and press "Quick Lock", it will automatically help you close positions of the same variety and quantity, but in the opposite direction. Especially when you have a certain profit, lock the warehouse. At this time, you are a profit lock, and at the same time, you will not lose opportunities because of new price changes. There are many benefits when the funds are large, but there is little significance when the funds are small.

For example, if you empty a variety, the opening price is the limit, and you have earned a lot. At this time, you can open more orders that are the same as your empty orders, that is, lock the warehouse and lock the profit. The reason for doing this is that you are afraid that the price may rebound, thus reducing your profit, so that your existing profit will not change because of the price fluctuation when the price rebounds. When the price is pulled up, you can make money for the second decline by taking out your multiple orders, but if you take out your empty orders and make unilateral multiple orders at the limit, then if the price does not rise, but continues to open sharply lower the next day, then you will not make money but lose money. Of course, after this, you are likely to lose the profit brought by the second possible decline, but at least you won't lose money.

In short, if you do this well, you can reduce the cost of your position and have the opportunity to maximize your profit in a relatively safe situation.
