2. Fishermen often participate in distant month contracts or quarterly contracts, and the transactions are relatively light. Due to the small transaction volume, only the fishing list will be left in the pending orders, and the pending orders of other investors will accidentally match the "fishing list" of the suspension board.
3. "Fishing list" takes advantage of the psychology that market participants are more or less eager to catch up. When the market trend suddenly changes, the market participants often hang up the market price list urgently. At this time, due to the small trading volume, it is often the fisherman who succeeds, and the investors who are caught suffer heavy losses.
