Futures lock-in has the function of locking future trading income and futures investment risk. In the actual transaction, you can also lock the position first and wait for the next day to close the position to avoid the high handling fee caused by closing the position on the opening day and avoid the substantial increase in transaction costs caused by closing the position on the same day.
Futures locking is usually used in speculative trading, which can lock in profits and avoid retracement in trend trading. In addition, futures lock-in can effectively reduce the market risks that investors should deal with, and give full play to the professional risk speculation ability of futures investors, so as to achieve the purpose of investors obtaining stable income and reducing economic losses.
