Futures lock-in means that investors open positions with the same amount but in the opposite direction when they participate in futures trading. In other words, if an investor holds five long positions in a futures contract and then opens five short positions in the same futures contract, a locked position is formed. This locking operation can lock the profit and loss of the account, and the profit and loss of the position will not change regardless of the market ups and downs.

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.
