In this way, no matter how the price of methanol fluctuates, there will always be losses and gains, and because the number of lots is the same, the losses and gains are always equal.
Locking positions can lock in losses, or lock in profits, saving fees, and also can lock positions urgently under special circumstances to prevent the market from jumping and exploding positions. This is the role of locking positions.
One of the reasons for the need to lock the warehouse is that the closing fee for some varieties is relatively expensive, and the closing fee is cheap every other day. Therefore, if you want to close your position in one day, you can switch to lock your position and close two orders the next day, which will save some handling fees.
For example, the Shanghai and Shenzhen 300 stock index futures, the opening fee of 30 yuan, the closing fee of 450 yuan, but the closing fee of the next day is only 30 yuan.
If you trade a CSI 300 futures today and want to sell it before the afternoon closing, the handling fee is * * *.
30+450=480 yuan.
If you lock the warehouse and sell it the next day, the handling fee is
30+30+30+30= 120 yuan, is it much cheaper? In fact, many domestic futures varieties are like this, and such liquidation methods can be adopted.
The second reason is to prevent high opening or low opening gaps from causing positions to explode.
It is easy for domestic futures to open higher and go lower after a long holiday, because some varieties with strong correlation, such as crude oil, soybeans and iron ore, etc. , all closed in China, while the international market fluctuated normally and did not stop trading.
It can lock the position, even if the position is opened higher or lower, the profit and loss of the position will remain unchanged, and there will be no penetration or explosion of the position.
