It's hard to say. This time it is obvious that a new wave of buying has broken through the pressure line. The most obvious thing is that the net copper is added to the warehouse, and the net clearance is reduced. I'm afraid this trend will continue in the later period. Coupled with the expectation of future economic recovery, it will stimulate the demand for metals.

There are several situations at present:

1, the main contract of zn is now moved to Yuanyue, with daily limit in recent months, lightening positions and increasing positions to Yuanyue.

2. There are also cases where the position of the same month is locked in the late session. Then it is better to close the position, or you need to pay a bilateral handling fee.

3. If you are bearish against the trend, in addition to spot hedging, the risk of shorting against the trend is slightly higher at this time.

4. Cross-month arbitrage. The more common method is: when there is a daily limit in recent months and far months, how far the month is and how empty the month is on the premise of being weak and strong and bullish. Lock the position for the whole month at the end of the trading day to avoid the risk of changes over the weekend.
