What do you mean by changing hands with bulls, changing hands with bears, opening positions with bulls, closing positions with bears, and closing positions with bears and closing positions on both sides? Multi-position transaction refers to a trader who originally held multiple orders and wanted to close the long position, and then took the initiative to sell and close the position at the current price (purchase price). At this time, the bills they match are all multi-warehouse receipts (of course, the number of lots of multi-warehouse receipts and multi-warehouse receipts is the same at this time). Because the number of positions has not changed during the whole trading process, long positions have only changed from one trader to another, so it is called "multi-position change"

Short selling means that the trader who originally held an empty order wants to close the position, so he takes the initiative to buy and close the position at the current price (selling price). At this time, all the orders he matched were short warehouse receipts (of course, the number of hands to buy closed positions is the same as that to short warehouse receipts). Because the position has not changed during the whole trading process, the short position is only transferred from one trader to another, so it is called "short position changing hands".
