ATR levels from the previous close: trigger lines, Golden Gate 38.2% and 61.8% levels, full ATR range, extensions, signals and dashboard.
Overview
This community script plots ATR-based levels around the previous period's close. It draws the previous close, call and put triggers, the 38.2% Golden Gate level, 50%, the 61.8% gate target, 78.6% and the full plus or minus one ATR range, with optional extensions beyond it.
It can also show previous period and premarket highs and lows, a 10-minute EMA8, entry and exit labels, Golden Gate candle colors, shaded trigger and gate areas, a dashboard, an info table and a legend.
How it works
The levels use ATR(14) from the period you choose (day trading by default) measured from the previous close. The trigger sits 0.236 of an ATR from the close by default.
Signals mark a confirmed close through the trigger (enter), a close back through it (exit), the gate opening at 38.2% and completing at 61.8%, pullbacks to the trigger or EMA8, and a first-hour reclaim of the previous close. Entries per direction, cooldown and buffers are adjustable.
One mode adds statistics researched on SPY/SPX on the 3-minute chart during regular hours; a universal mode keeps the same levels on any market and hides the statistics.
How to use it
- Use the levels as a daily map of how far price has moved relative to its average range.
- Some traders watch the 38.2% to 61.8% zone after price crosses a trigger.
- Use the dashboard to see distance to the next level.
- Switch to universal mode on other markets so the SPY-only statistics stay hidden.
These are ways some traders read it, for learning. They are not trade signals.

Notes and limits

- Levels reset each period based on the session setting.
- It draws many labels; Simple Mode keeps only the main levels.
