Ticked at me

One of high % setup is to fade a gap fill. Just about 5 mins ago, YM was coming to fill the gap, so I placed an order to fade it (short). Yesterday's close was 11955 I think, so I placed a bit higher than that at 11960. I patiently waited and it finally came up, but guess what. 11960 was traded but I didn't get filled. If you know YM, sometimes there are lots of orders sitting, but mostly 5-15 lots. I put 30 pts stop and target. In a matter of 30 secs, the target was hit. It could have been a stopout trade, but I feel like when I don't get in, it is a winner.
