Just a simple guage around expiration week for ES... Look at the previous session's option settlements and where the 5 point puts and calls are... should give you an approximate swing range for the next session... ie.. 9/18 1130 - 1190. Today... Watch it tighten and scalp away
New range: 1115 - 1165 at noon on 9/18. 50 point swing this afternoon... dip first and checkup at close or checkup first and nose dive at close?
