At 0750, 0850, 1050 ,1350 &1630 an Auction call starts on all SETSQX stocks. At 0800, 0900, 1100, 1400 and 1635 a scheduled auction un-crossing applies. During these 10 minutes each trading day (5 minutes at close) orders are visible on the order book (if you have level 2 data or Direct Market Access).
During these 10 minutes instead of having to accept a market maker quote you can participate in the auction to try to form a match at better prices than current market maker prices. A PME will occur if no match takes place and it would extend for 5 or possible further final 5 minutes to allow amendments/deletions.
In general use ignore PME's as they only benefit you if you have Level2 data or DMA
