Overnight & ETH Levels
By LuxAlgoApr 27, 2026
Overnight & ETH Levels is an indicator on Vela, our next-generation charting platform, written in Pine Script®.
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 each high and low through untested, tested, broken, and faded states, marking ON Mid as reached once price touches it.
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.
