Overnight & ETH Levels

Overnight & ETH Levels freezes the overnight and ETH levels (the extremes formed outside regular hours) at the regular-session open and extends them across the day. The overnight window (18:00–09:30 New York time by default) supplies the overnight high, low, and midpoint (ONH, ONL, ON Mid); an optional pre-market window adds PMH and PML. While a window forms, its running extremes draw as dotted developing lines, and a dashboard classifies where the regular session opened relative to the overnight range and walks every level through untested, tested, broken, and faded states.

How to Trade the Overnight & ETH Levels?

  • Open above ONH / below ONL: an out-of-range open: watch for acceptance or the fade back inside; both open-location alerts fire at the bell.
  • Broken: a close beyond a level is acceptance in the break's direction.
  • Faded: a close back inside after a break is the failed-break read, the classic cue for rotation back across the range.
  • ON Mid reached: overnight inventory corrected back to the middle of the range.

Each level carries test and break alerts, the overnight extremes add fade alerts, and the midpoint has a touch alert.

Overnight & ETH Levels Settings

  • Regular Session (RTH) (default 0930-1600): where the levels freeze and are tracked.
  • Pre-Market Session (default enabled, 0400-0930): also track PMH and PML.
